Robert Downey Jr. once told Anthony Russo and Joe Russo about how one of his children said "I love you 3000" to him. The directors liked the phrase so much that they decided to include it in the film.

Shot back-to-back with Avengers: Infinity War (2018) over a period of 200 days.

The idea of showing the autographs for the original The Avengers (2012) actors in the end credits came from Star Trek VI: The Undiscovered Country (1991), which was also a finale for its cast.

In the scene where Black Widow coordinates the remaining Avengers, her ballerina shoes can be seen on a chair. This is a nod to Natasha's past in the Red Room where she was trained (Avengers: Age of Ultron (2015)).

Robert Downey Jr. officially surpassed Hugh Jackman's record for most appearances in film as the same superhero, with ten. He set this record in only 11 years, whereas Jackman did it in 17.

Natalie Portman's appearance in the film was created with leftover footage from Thor: The Dark World (2013), and she also did voice-over work for a scene when she is talking in the distance. Although Portman didn't shoot any new scenes, she attended the film's premiere.

Evangeline Lilly and Paul Rudd were filming Ant-Man and the Wasp (2018) and this film at the same time.

Robert Downey Jr. was the only actor who read the entire script.

The final cameo by Stan Lee in a Marvel film.

When Avengers: Endgame (2019) passed Titanic (1997)'s box office total, James Cameron sent a congratulatory message to Kevin Feige and Marvel Studios on dethroning his film - with a photo of the Avengers 'A' being the iceberg that sinks the Titanic.

As they did with the previous film, the Russo Brothers wrote a letter to fans, asking them not to spoil anything about the movie, as part of a viral campaign on the internet. The hashtags were #DontSpoilTheEndgame and #ThanosDemandsYourSilence.

Even though Captain Marvel (2019) was released one month before this film, Brie Larson shot her scenes for this movie first. The scene at Avenger's Headquarters was Brie Larson's first day on set as Carol Danvers. The directors of Captain Marvel had to be present on-set during the filming of her scenes to ensure consistency of portrayal.

Director Joe Russo's daughters Ava Russo and Lia Mariella Russo portrayed, respectively, Hawkeye's daughter (Lila Barton) and one of Professor Hulk's fan wanting autographs and selfies.

This is the first (and, given his announced "semi-retirement", presumably the only) film where Robert Redford has returned to play a role for a second time. In his 59-year career, Redford has otherwise never played the same role twice in a franchise.

This film earned $60 million in Thursday night previews, breaking the $57 million record held by Star Wars: Episode VII - The Force Awakens (2015).

Avengers: Endgame (2019) became the biggest pre-sale title ever on Fandango and Atom Tickets sites, causing them to crash minutes after the sales were announced. It accomplished this feat in only six hours. Some theaters across the globe had so many sold-out showtimes on the opening weekend that Cinemark, Regal, and AMC theaters chose to add new overnight screenings so that they would be working around the clock to accommodate extra shows. Endgame would go on to become the highest grossing film of all time, at little under $2.8 billion worldwide.

Marvel Studios President Kevin Feige credited "Star Trek: The Next Generation: All Good Things... (1994)", the series finale episode of Star Trek: The Next Generation (1987), as inspiration for this film.

Filming officially began on August 10, 2017. It was shot after a three- to five-week break once Avengers: Infinity War (2018), which started filming on January 23, 2017, wrapped.

"Avengers: Endgame" is the first film to reach over a billion dollars during its opening weekend in theaters.

Avengers: Endgame and its predecessor, Avengers: Infinity War (2018), were filmed entirely on digital IMAX cameras, making them the first Hollywood films shot entirely on IMAX cameras, in an exclusive open-matte aspect ratio of 1.90:1. Unfortunately, standard theaters and Home Media Releases of the film are cropped to the Letterbox ratio of 2.39:1.

Scott Lang's storage unit number is 616, which is the same number used for the primary continuity (Earth-616) of the Marvel Comics Universe.

Tony's extreme weight loss was done through VFX.

Sometimes Robert Downey Jr. would bring musicians on set to play during lunch.

Robert Downey Jr. hid his own personal snacks all over set. The scenes where he's eating snacks and offers them to his costars were all improvised.

Upon the memorial for all the snap victims is the name Roberto de Costa AKA Sunspot. The first real confirmation of an X-Men character in the MCU.

In September 2018 the Russo Brothers posted a picture on social media of the film's set with the caption "Look Hard." This led many to speculate that the title of this film was hidden somewhere inside the photo. (In fact, the film's subtitle, "Endgame," can be made out by the shapes and layout of the objects in the image.)

Marvel Entertainment titled the first trailer as "Marvel Studios' Avengers - Official Trailer," without the film's title in the name of the video, in order to surprise the fans with the title's reveal at the end of the trailer.

This is the fourth time the MCU movies visit Norway, and the third time visiting the Norwegian city of Tønsberg. Tønsberg appears in Thor (2011), and is the place where the Tessaract is found in the beginning of Captain America: The First Avenger (2011). In Avengers: Age of Ultron (2015), Tony Stark visits Oslo, the capital of Norway. Tønsberg is the oldest city in Norway, dating back to 871, and has roots in the Norse era.

When we see Hank Pym in his lab in the past, we can clearly see a large, rounded, metal helmet with eye holes and antennae. This helmet resembles the Hank Pym Ant-Man's helmet out of the original Ant-Man comics and Avengers comics.

The North American release date was moved up a week earlier, from May 3rd to April 26, 2019, after the first trailer and title released on December 7, 2018. There was much speculation that Marvel Studios would do this, as they moved Avengers: Infinity War (2018)'s release up a week as well, in order to reduce the possibility of major plot leaks from countries that released the film earlier.

Korg (Taika Waititi) is seen wearing the same Hawaiian print shirt that Waititi wore at San Diego Comic Con while promoting Thor: Ragnarok (2017).

The Quantum Suits are entirely created with VFX.

This was the twenty-second film to be released by Marvel Studios for the Marvel Cinematic Universe.

The 573 area code shown for Laura Barton's phone number suggests that the Barton family farm is located in central/eastern Missouri, as this is the area code for most of the eastern half of the state outside of the St. Louis metro area. This is confirmed when we see a truck at the Barton farm with a Missouri license plate.

This film marked Chapter Ten of Phase Three in the Marvel Cinematic Universe.

The jokes about "America's ass" were apparently the most controversial in the film. "It was hotly debated."

Paul Rudd never actually wore the Ant-Man suit while filming, it was added with VFX. This is a lie

In Marvel Comics, there was a period of time where Bruce Banner's consciousness embodied the Hulk's physical body. This however, was achieved through a joint effort of Doctor Strange and Bruce's longtime friend, Dr. Leonard Samson (who was also irradiated by gamma rays). The result, however, was different than what's seen in the film. Instead of a balanced Bruce Banner/Hulk as we see in "Endgame", Samson and Strange managed to merge the three consciousnesses of Hulk (Green), Joe Fixit (Grey), and Bruce Banner so that whenever Bruce was in control, the Hulk's body would surface. But if he lost his temper and the Savage Hulk persona came out, he would transform into the diminutive body of Bruce Banner. In another storyline, Samson and the villainous Ringmaster merge the of Banner's separate personalities into a being who closely resembles the film character. Banner's intellect controlled a body that looked more like Banner than the Hulk's monstrous form.

Carol's new look after the time skip is inspired by the comics on two counts. Her short hair has been carried over from her modern design, as has the red sash she wears as a belt. Her new red costume with black shoulder-pads is lifted directly from Captain Mar-Vell's, Carol's predecessor. Additionally, it's subtle, but Carol showing concern for Rhodey and telling him to be safe is a reference to their recent romantic relationship in the comics.

The opening Hawkeye scene was originally conceived as part of the finale of Avengers: Infinity War (2018). However, because Hawkeye had not been featured throughout that film, the Russo Brothers moved the scene to the beginning of this movie.

Much of the dialogue in the debate scene about time travel came from conversations with real quantum scientists.

Karen Gillan appears in the scene where the characters discuss all the films that have involved time travel. She later said she wished she had thought of making a reference to Doctor Who (2005), on which she had appeared. The "Time Heist" premise is the title of a "Doctor Who" episode, and Bill & Ted travel around in a phone booth, similar to the Doctor's TARDIS.

Thanos being Iron Man's antithesis and personal archenemy for the MCU lies on Thanos's original appearance as an Iron Man villain back in 1973.

This is the first film in the series to feature the original line-up of the Avengers from the comics: Captain America, Iron Man, Thor, The Hulk, Ant-Man (Hank Pym) and The Wasp (Janet Van Dyne).

The scenes in New Asgard were shot in St. Abbs, a village on the southern coast of Scotland.

Opening night tickets were resold on eBay for thousands of dollars, with a pair of IMAX tickets in New Jersey selling for $15,000.

As declared by himself on set, Robert Redford's last movie role. The legendary actor declared this was his final acting performance the day he arrived for filming.

Back to the Future is mocked very often in this movie. Alan Silvestri, who scored every Avengers movie (Except Avengers: Age of Ultron (2015))including Avengers: Endgame, also scored the Back to the Future trilogy.

The subtitle "Endgame" had been speculated due to the phrase "We're in the Endgame now" by Doctor Strange in Avengers: Infinity War (2018). This theory seemed to be confirmed after someone looked up cinematographer Trent Opaloch's profile and noticed "Avengers: Endgame" in his list of projects; however, that was automatically changed and the Russos denied the title. The first trailer released on December 7th, 2018 officially confirmed Endgame to be the title.

The Russo's find value in serialized storytelling with scenes like Stark giving Rogers his shield as part of his apology and their renewed friendship. "If you make choices that take years to resolve the audience feels that because they too have waited years for this to resolve."

This film marked composer Alan Silvestri's fourth time composing a movie in the Marvel Cinematic Universe, with his first three being Captain America: The First Avenger (2011), The Avengers (2012), and Avengers: Infinity War (2018).

After the five year time skip, Natasha gets a report from Okoye about an earthquake under the Atlantic Ocean. In the Marvel comics, the Atlantic is the home of the underwater kingdom of Atlantis, ruled by the Marvel hero Namor the Sub-Mariner. When asked if this was meant to reference the character, co-writer Christopher Markus confirmed that it was unintentional.

The Russo's love that genre films and technology can allow this kind of storytelling. "You have the opportunity to take a son and put him in a scene with his own father where the son is older than the father, the son has a child so has more experience in parenting than the father whose wife is pregnant with the son."

Iron Man's Mark 85 armor resembles a somewhat modernized but otherwise completely accurate recreation of his classic Mark 2 Armor (the first red and gold one) in the comics, while Cap's new suit finally incorporates the classic chainmail design of his comics outfit. The Mark 85 armor also has a built-in energy shield that resembles the one Iron Man has in the Marvel vs. Capcom video games.

The Russo Brothers thought of making 2014 Thanos massacre all the Avengers in another timeline and decapitate Captain America, then bring his decapitated head In the original timeline to taunt the Avengers. However, the thought was considered too violent and was ultimately dropped.

Athens, Georgia, brewery Creature Comforts is featured in both the trailer and the movie. Thor is seen drinking an Athena Berliner Weisse and later seen drinking a Tropicalia IPA. Joe Russo was paying homage to his favorite local brewery in Georgia (where the movie was filmed) by featuring their beer in the movie.

Scarlet Witch's powers are directly influenced by her internal struggle. She has grown more powerful as she deals with the death of Vision.

The Russos praise the writers for crafting dialogue that continually feels true to the character speaking it. "If you find yourself having your character say something anybody in the room could have said then it's time to go back to the drawing board."

The end of Infinity War left the writers trying to write their way out of a corner, and while they considered time travel as the answer they also knew that was "the stupidest idea" they could possibly have. The Ant-Man films argued otherwise, though, as they offer up the seeds of a time machine, and ultimately it won them over as time travel allowed for multiple scenes highlighting the emotion of loss, reunion, and redemption.

The first poster released featured Okoye, but did not include Danai Gurira's name among the rest of the cast members' names at the top of the poster. That poster was quickly recalled and replaced with one that did include her name.

The Smart Hulk appearance originally occurred in Wakanda during Infinity War which had him rip out of the armor suit and beat the crap out of Cull Obsidian. They canned it because "the movie could not handle this weird success." The film needed to stay focused on losses, so they cut the sequences out of Infinity War even as they were editing Endgame. A handful of preview audiences saw it before the scene was cut and apparently didn't love the tonal confusion.

The Stan Lee cameo is based on his own actual look in the 1970s. They used Lola Visual Effects to de-age Lee back to his 70s self.

When the Russo Brothers tweeted out a photo of the re-shoot cast, Yvette Nicole Brown from Community (2009) was in that photo, making her at least the fourth cast member from "Community" to appear in a Russo Bros. MCU film, following Danny Pudi and D.C. Pierson in Captain America: The Winter Soldier (2014) and Jim Rash in Captain America: Civil War (2016). (Fellow "Community" star Ken Jeong also appears in this film, as does Brie Larson, who guest-starred in a few episodes of the show.) Before their work with Marvel Studios, directors Anthony Russo and Joe Russo were known for their work producing and directing TV comedies, including "Community", where they served as executive producers during the first three seasons. (Elsewhere in the MCU, "Community" star Donald Glover appears in the non-Russo Bros. film Spider-Man: Homecoming (2017), as Aaron Davis, the criminal Spider-Man tries to interrogate about the Vulture's weapons ring and uncle of future Spider-Man Miles Morales.)

The Asgardian soldiers in pursuit of Rocket call him a rabbit, just as Thor did in Avengers: Infinity War (2018).

On September 11, 2017, the production of the movie was temporarily shut down because of Hurricane Irma.

This is the final cameo of Stan Lee in an MCU film.

During an event for Guardians of the Galaxy Vol. 2 (2017) in April 2017, Zoe Saldana revealed the title of the film as "Avengers: Infinity Gauntlet". Following this, James Gunn announced that was not the title.

Not counting her cameo in Captain Marvel (2019) or the recycled footage in Thor: Ragnarok (2017), "Endgame" marks the seventh time that Scarlett Johansson plays the character of Natasha Romanoff/Black Widow in the Marvel Cinematic Universe, following Iron Man 2 (2010), The Avengers (2012), Captain America: The Winter Soldier (2014), Avengers: Age of Ultron (2015), Captain America: Civil War (2016), and Avengers: Infinity War (2018).

One of the Russo's favorite shots in the film is seeing Captain America/Steve Rogers go to space for the first time.

A lot of scenes had to be left on the cutting room floor. including an aerial battle, which would have featured Sean Gunn's Kraglin. Kraglin is a quirky side character in the Guardians of the Galaxy franchise, played by James Gunn's brother Sean (who is also the stand-in for Rocket during filming). After Endgame was released, a set photo was revealed of Sean Gunn filming as Kraglin, revealing that the Ravager leader was somewhere in that final battle against Thanos. He recently opened up about that deleted sequence, saying: "All I can tell you is really what we shot. Obviously, some of the fragment footage was cut from the final battle for good reason. From a narrative standpoint, they didn't want to cut to the Battle of the Sky, which makes sense, but I all I can say is that Kraglin was wearing his fin. He had the Yaka arrow on him, but it was sheathed and remained sheathed. So, I think all of that qualifies as canon, and the rest of it is up to anyone to speculate on that one." Not only did Kraglin have a deleted role in Avengers: Endgame, but we also would have gotten a brief appearance from Youndu's signature arrow. Even if he didn't actually use it in the battle.

Thanos uses his discarded armor as a scarecrow, just like at the end of "The Infinity Gauntlet".

Screenwriter Stephen McFeely has stated that at one point during development the story would have seen Tony Stark visiting Asgard during the events of Thor: The Dark World (2013) as both the Aether (Reality Stone) and the Tesseract [Space Stone] were located there at the same time. He went on to add that as part of this sequence Stark would have had an invisible stealth suit and had to fight Heimdall Idris Elba who could see him despite his invisibility. Ultimately the Russo Brothers decided to set the main time travel events of the movie during The Avengers (2012) and this plan was abandoned.

Robert Downey Jr. was born in 1965, making him 54 (and only just at that) at the time this film was released. Tony Stark was born in 1970, making him 53 when this story takes place.

The very premise of the Avengers splitting up into several smaller groups to travel across time and space seems to have been inspired by Kurt Busiek's "Avengers Forever". The official sampler that Marvel released for new readers who might be interested in getting into comics after seeing "Endgame" even listed "Avengers Forever" alongside other stories that were relevant to the movie, like the original "The Infinity Gauntlet" mini-series.

When Tony calls Rocket a Build-A-Bear, Rocket says, "Maybe I am." Rocket is a raccoon-like mammal that was torn apart and rebuilt...in essence a mad scientist's version of a Build-A-Bear.

During the scenes set in 1970, Howard Stark mentions Arnim Zola, revealing that the former war-time enemies were working together at S.H.I.E.L.D. at this time.

Natasha pulling Clint out of his murderous spiral is payback for his having saved her from her own life as an assassin.

The film was formerly known as "Avengers: Infinity War, Part II."

There was a version of the scene written that saw Hawkeye attack Hulk out of anger after being pulled out of the past.

The Russo's were thrilled once they hit on the idea of revisiting past films through the "time heist" because it offered opportunities to talk about and comment on them directly. "This is a good example, Thor: The Dark World (2013) has a kind of confusing back story."

Mantis can be seen swaying during the funeral scene, which is a thing praying mantises actually do.

Half of the instruments used in the opening title card to Avengers: Infinity War (2018) are not present during the "Endgame" title card.

The post credits scene that is added for the rerelease of this film consists of a tribute to Stan Lee, a deleted Professor Hulk scene, and a sneak peek of Spider-Man: Far From Home.

The line "I am Iron Man" was suggested by the film's editor Jeffrey Ford.

In the 2012 elevator scene, Agent Sitwell mentions Dr. List. This was Baron Strucker's lead scientist seen in the end credits scene in Captain America: The Winter Soldier (2014) and at the start of Avengers: Age of Ultron (2015). He was not identified by name in either film, but this was revealed when he made a series of crossover appearances on Agents of S.H.I.E.L.D. (2013).

The opening Tokyo shot was filmed over two nights in Atlanta.

Barton being the first person after Scott to enter the Quantum Realm via shrinking is a nod to his time as the size-changing Goliath.

Banner managing to join his consciousness to the Hulk's bodies has happened multiple times in the comics, most notably with the "Merged/Professor Hulk" incarnation from Peter David's run.

Brie Larson as Carol Danvers/Captain Marvel has less than ten minutes of screen time. Screenwriter Stephen McFeely explained that they purposely limited the character's presence, because they wanted to focus on the old Avengers coping with the events of Avengers: Infinity War (2018). Another reason was that when Endgame was filmed, Captain Marvel (2019) had not even been written, so Brie Larson hadn't fully developed her character yet.

The opening scene with Hawkeye's family disappearing was originally intended to appear at the end of Avengers: Infinity War (2018), but they felt his sudden appearance was "too disorienting." Here, though, it works to re-establish the emotion.

It's meant to be understood that Captain Marvel's arrival outside the spaceship carrying Iron Man and Nebula occurs after she's visited Earth, spoke to the remaining Avengers, and then followed a homing beacon emanating from the ship. This reveal wasn't part of earlier cuts, and instead, they had her first appearance as she brings the ship to Avengers headquarters.

On the planet Morag, Natasha kicks a squawking alien rat, just like Star-Lord did when he first landed there in Guardians of the Galaxy.

Cap refers to Spider-Man as "Queens" during the race to retrieve the Nano Gauntlet, calling back to their playful banter from Captain America: Civil War.

The suits that the Avengers used to travel through the Quantum Realm are similar in design and color-scheme to the space suits worn by the Avengers from The Avengers: Earth's Mightiest Heroes (2010).

Rocket wears a new outfit that is very similar to what he wore in the beloved Guardians of the Galaxy run by Dan Abnett and Andy Lanning.

Haley Atwell, who plays Peggy Carter in numerous Avengers projects, shared with IGN whether or not Chris Evans' Steve Rogers would have told her character about kissing Sharon Carter, Peggy's great-niece. "Probably, in a very awkward way, that probably meant there was a domestic," Atwell explains. "Words were said, voices may have risen. Wouldn't that be hilarious? If they had a proper argument about it and she just slams the door and he goes off fishing for the weekend for something, I don't know," she says laughing. See gallery Atwell continues, "Because it's the '40s I think it can have such a beautiful, wholesome, kind of screwball comedy tone to it, rather than a soap opera. Let's write it now, let's do it," she adds

Of all the infinity stones to appear in the entire Marvel Cinematic Universe both the Space and Mind stones make the most appearances with seven and six movies respectively. For the Space stone, Thor, Captain America the First Avenger, The Avengers, Thor Ragnarok, Avengers Infinity War, Captain Marvel, and Avengers Endgame. For the Mind stone, Avengers, Captain America the Winter Soldier, Avengers Age of Ultron, Captain America Civil War, Avengers Infinity War and Avengers Endgame.

Joe Russo had a talk with Google about his career and his hit Marvel Cinematic Universe film. During the audience Q&A, one person compared Avengers: Endgame's success to the backlash of Game of Thrones' final season, and wanted to know where the Russos went right. "Obviously Endgame was an amazing movie," the audience member began. "The culmination of a ten-year storyline that either met or exceeded the wildest expectations that we had. There's another series that just recently finished, Game of Thrones, which actually followed a very different path did not meet any expectations-" "That's your opinion," Russo interjected. "I just want to make that clear. That is not my opinion." "Where do you think you went right with the Avengers storyline and where did Game of Thrones go wring," they asked. "This is like 20,000 headlines for the next three weeks if I answer this question," Russo joked. "Look, it's interesting being an artist in today's world with social media because it's an unprecedented level of ownership that the viewer feels over the material. When I grew up, Ernest Hemingway wanted to write a book, he wrote a book and you read and went 'that's great' and 'amazing' and 'thank you, Ernest Hemingway, for writing an incredible piece of literature.' You're very grateful for it. Today, rightly or wrongly, there is an intense amount of ownership and opinion, and opinions fly fast and furious. I've learned this about social media, that there's a minority of opinions that are very loud, and they tend to drive the media cycle in a way where it's not healthy because you're not getting a true sampling of everyone's opinion." He added, "It takes energy to go online and bitch about something, you know, and not all of us have that energy or care to do it. You know, it's also a little bit of narcissism that's involved with getting online to complain about something, so you have to have the combination of those things in order to do that and I don't think that's evocative of a large segment of society. I'm sorry, I'm not answering your question directly. I'm trying to give you a version of an answer." However, Russo did conclude with his own opinion about the final Game of Thrones season: "They made the choices that they wanted to make with that show and people felt, what I think that they felt, was that they didn't feel it was seeded properly throughout the series," he shared. "I loved all the choices. I thought they were crazy and unexpected, and that's what I want out of a narrative, but I see where people feel like they were upset." "I'm glad we didn't get as beat up," he added with a laugh.

Thor has Hulk and Iron Man PEZ dispensers in his room next to Stormbreaker.

As of July 21 2019, "Avengers: Endgame" has become the top grossing movie of all time (inflation not adjusted), beating out Avatar (2009) (which has made $2,789,700,000) after its re-release, with $2,790,216,193.

They had been debating how to handle the Thanos side of the story this time around as he's "comically powerful" and has already beat them silly once. "What is a two-hour movie where you're playing cat and mouse with that guy?" The comics work past this by essentially having Thanos "tie one hand behind his back," but they didn't want to go that route here. The answer came from producer Trinh Tran who said one day, "Kind of really wish we could just kill him." That opened their eyes and ultimately allowed for a different and unexpected film.

One sequence cut from the second act took place while the team is watching the Battle of New York. Rocket makes a crack asking Rogers "how long did you fight these guys?!" Rogers replies that it took a couple hours and Rocket gives him grief for not immediately blowing up the mother ship.

Bruce was called "Smart Hulk" throughout the shoot.

Rogers fighting his slightly younger self is meant to influence the decision he makes later in the film "because he sees his past self and what a hard nut he is."

Three actors from Avengers: Endgame (2019) have portrayed Sherlock Holmes. Robert Downey Jr. (Tony Stark/Iron Man) starred in Sherlock Holmes (2009) and Sherlock Holmes: A Game of Shadows (2012). Benedict Cumberbatch (Dr. Stephen Strange) was BBC's Sherlock (2010-2017). And James D'Arcy (Edwin Jarvis) appeared in the TV movie Sherlock (2002).

Brie Larson (Captain Marvel/Carol Danvers) and Chris Evans (Captain America/Steve Rogers) had previously starred together in Scott Pilgrim vs. the World (2010) before either of their appearances in the Marvel Cinematic Universe. Larson played the rock star Envy Adams (Scott's (Michael Cera's) ex-girlfriend), and Evans played the action movie star Lucas Lee (one of Ramona's (Mary Elizabeth Winstead's) Seven Evil Exes). In addition, that movie was directed and co-written by Edgar Wright, who wrote the original screenplay for Ant-Man (2015) (a character who also appears in this movie), but dropped out as director for that movie due to his creative clashes with Marvel Studios.

Smart Hulk was originally supposed to come out during Marvel Studios' "Avengers: Infinity War", but was removed during editing.

The writers and directors toyed with the idea of giving Hulk his rematch with Thanos. Concept art for the scene idea was shown at the D23 Expo. A fan took a photo of the artwork and shared it to Reddit, along with similar artwork for other scenes, including one showing Iron Man, War Machine, Rescue, and Spider-Man flying into action and another showing a battlefield kiss between Tony Stark and Pepper Potts. In an interview, writers Stephen McFeely and Christopher Markus explained why the rematch didn't happen. "The battle had all sorts of stuff in it. I don't know how long that battle is now, but it's not as long as you might think," McFeely said. "I know a lot of people were saying they can't wait for [Hulk and Thanos'] rematch. Well, that would've made sense had he not become Smart Hulk. He's a whole different thing, and that's not what drives him. So we never thought, 'Oh, he really is trying to get a crack at Thanos now.'" At San Diego Comic-Con, the writers revealed they'd planned to introduce Smark Hulk at the end of Avengers: Infinity War. They nixed that plan because they felt it was "completely the wrong tone for that moment in the movie," according to Markus. "It was this victory when we were headed toward a crushing defeat, and it was tone-deaf," Markus said. "But we had already shot Endgame, where he was already Smart Hulk." "Imagine the first act of Endgame, he's Smart Hulk in all of those scenes -- meaning when he goes to kill Thanos when they're sitting around the compound when Tony's returned -- so that required some adjusting," said McFeely. "And it also meant that we could use the five years as the transition, hint that he's got problems coalescing, and in the five years he figures it out. You have a couple of lines about gamma radiation and he's eating pancakes, and off you go."

The look of Tokyo was inspired by the movie "Black Rain".

Hulk holding up debris to save Rocket and War Machine was inspired by Hulk lifting a mountain in the comics.

They give a shout out to Russell Bobbitt, Marvel's resident prop master, for the vintage Ant-Man helmet seen at (1:42:10).

One fan on Reddit has zeroed into one of the funnier moments in the movie and theorized that Cap might have turned himself into a HYDRA agent accidentally. The poster then goes on to explain how this development could tie into the upcoming Disney+ Loki series. Fans will remember Steve Rogers using his knowledge of the future to his advantage in securing the Tesseract back in the past. The hero was in an elevator full of Hydra agents and caught them all off-guard by whispering "Hail Hydra" when they asked what he was doing with the staff. This of course results in Cap having to fight a past version of himself, as the older version believes that his future self is Loki in disguise. Rogers knocks his double out with the scepter and goes on his way. ConstantCompile proposes that by using the stone to knock out past Cap, the hero could have put himself on the road to becoming a double agent in that timeline. Those Hydra agents on the elevator could end up finding him laying there and take him back to their headquarters for debriefing. The poster even goes so far as to wonder if Captain Americacould end up being an antagonist in the Loki Disney+ series because of this small exchange.

Screentime for every character between Infinity War and this film Tony Stark/Iron Man: 50 mins., Thanos: 37 mins., Steve Rogers/Captain America: 35 mins., Thor: 31 mins., Bruce Banner/Hulk: 25 mins., Gamora: 21 mins., Natasha Romanoff/Black Widow: 18 mins., Clint Barton/Hawkeye: 16 mins., Scott Lang/Ant-Man: 14 mins., Rocket Raccoon: 14 mins., Peter Quill/Star-Lord: 14 mins., Dr. Strange: 12 mins., Rhodey: 10 mins., Peter Parker/Spiderman: 9 mins., Wanda/Scarlett Witch: 9 mins., Vision: 7 mins., Drax: 6 mins., Pepper Potts. 5 mins., Ebony Maw: 5 mins., Samuel: 5 mins.

The most time spent during the editing process was spent trying to balance the story during the time heist sequence.

When asked how does it feel to know that "Endgame" is the top-grossing film of all time, Anthony Russo stated: "It feels surreal; it's a very hard idea to process. Somebody wrote recently that for the first time in 45 years, the highest-grossing movie ever was not directed by [Steven] Spielberg, [James] Cameron or [George] Lucas. Those are all our heroes; those are all people [who] we grew up watching their movies, and studying their films to learn how to become filmmakers, so it's weird. It's hard to process."

The final showdown between Thanos, Captain America, Thor, and Iron Man was inspired by the end of Once Upon a Time in the West.

That's not newly shot footage of Jane getting out of bed, it's an outtake from Thor: The Dark World (2013).

The Infinity Stone to make the fewest appearances in the Marvel Cinematic Universe is the Soul Stone, which only appears in Avengers: Infinity War and Avengers: Endgame.

During battle, Thanos grabs Captain America's wrist because he isn't worthy of holding Mjolnir.

Elizabeth Olsen knows her character could take down Thanos by herself, as she explained in an interview with IMDB while appearing at D23 Expo. "Yeah, he brought out the big guns he didn't even mean to bring out. I was getting him good," Olsen said. "Hello, someone was angry, and had somethin' to say about it. And it was this one right here," she added, pointing to herself.

Given how the Russos along with Marvel Studios President Kevin Feige fought tooth and nail to incorporate Tom Holland's Spider-Man into the MCU, they're sad to see him go, but enjoyed the ride. "We were extremely passionate about it. This is something we really wanted to happen, and fought a long time internally at Marvel to make it happen," Anthony Russo says of bringing Holland's Spider-Man into the fold. "It wasn't easy," adds Joe Russo. "Kevin [Feige] went through a lot. There were a lot of ups and downs, and he kept walking into our office and we'd go, 'Look, we've got to do it with [Sony],' and he'd go, 'OK, I'll figure it out,' and walk back into his. He was looking for the way out. He wanted to open that door and have us go, 'We figured it out! We don't need Spider-Man!' because it's a lot of work to get two major corporations to play nice with each other, and the fact that it happened at all, we should all be dancing and celebrating that we got that little bit of time." "I think that's why Joe and I are not so devastated or surprised that there's been a falling-out, because it was so hard to make it happen in the first place," offers Anthony Russo.

The "Five Years Later" text is followed by a cooler, grimmer color timing meant to highlight the grief of five years gone.

McFeely added a personal Easter Egg with Stark's mention of bringing sauerkraut to his pregnant wife as his own mother craved it while pregnant with him.

The intention behind the self-help group meeting is to show that the snap has affected everyone, not just heroes.

It was Kevin Feige's idea for the end credits to feature a curtain call for the original Avengers.

When Captain America picks up Mjolnir to fight Thanos. Thor's proud exclamation "I knew it!" calls back to the party scene in Avengers: Age of Ultron where Cap almost succeeded in lifting the hammer. Back then, Thor was worried, but by now he's grown enough as a person to feel nothing but pride in his comrade's worthiness.

This is the first film to get a theatrical re-release and extended version before the DVD and Blu-Ray release. Head producer at Marvel Kevin Fiege opted for this to top Avatar (2009) in the global box office.

The scene at Avenger's Headquarters was Brie Larson's first day on set as Carol Danvers, it was shot before Marvel Studios' Captain Marvel went into production.

Early cuts had the reveal of Captain Marvel held off until the moment she arrives on Earth.

First live-action film appearance of Spider-Man after the deaths of his co-creators Steve Ditko and Stan Lee, and the second overall, after Spider-Man: Into the Spider-Verse (2018). Ditko died in June 2018 and Lee died in November 2018, both coming after Spider-Man's appearance in Avengers: Infinity War (2018) (April 2018), but prior to the release of "Spider-Man: Into the Spider-Verse" (December 2018).

Josh Brolin, who played Thanos, has the most screen time in "Infinity War" and the least in "Endgame".

Above the stage at the support group meeting is the inscription "For God and Country, In Memorial to Chaplain Matthew Haggerty". Matt Haggerty was the 2nd assistant director for both Avengers: Infinity War (2018) and Avengers: Endgame (2019), as well as Arrested Development (2003) in which the Russo Brothers directed several episodes.

Rhodey mentions Star Trek in his list of films about time travel. The Marvel Cinematic Universe has featured several actors from the Star Trek franchise: Damion Poitier, Miguel Ferrer, Chris Hemsworth, Alice Krige, Karl Urban, Benedict Cumberbatch, Idris Elba, and Zoe Saldana.

The Russo Brothers begin shooting days with rehearsal, which allows for script changes to be implemented by the time of shooting in the afternoon.

Each of the three Captain America movies features a moment where a battered Steve Rogers stands up to an enemy and says, "I can do this all day." Endgame subverts it by having a circa-2012 Cap say it to his older self. Apparently, Cap isn't fond of having his catchphrase thrown back at him.

When Thanos faces Scarlet Witch he says "I don't even know who you are." Josh Brolin and Elizabeth Olsen, who played the respective characters, also starred in "Old Boy", a crucial plot development of which was that he doesn't know her true identity.

There was a brief time during the writing stage that saw Thanos returning to Earth and tossing 2012 Captain America's head on the floor.

Iron Man had the most screen time in Infinity War and Avengers: Endgame at 3,001 seconds, which breaks down to a little less than an hour between both movies at roughly 50 minutes of screen time. Thanos came in second place with an impressive 2,272 seconds (nearly 38 minutes of screen time). Third is Steve Rogers, who ended up with 2,121 seconds for third place, giving us a screen time of just over 35 minutes. Bruce Banner picked up a lot of extra seconds in the latest installment too, as he is in fourth place at 1,528 seconds, just 25 minutes. The character with the fifth highest amount of screen time is Gamora with 1,275 seconds, or just over 21 minutes.

When we see 2012 Thor mention going for a "bit of lunch," it's a reference to the post-credit scene from The Avengers, where the group is seen eating shawarma.

This was the first MCU film to feature both the Hulk and Ant-Man. Paul Rudd previously appeared in I Love You, Man (2009), which also featured the original Hulk, Lou Ferrigno. Ant-Man (2015) also featured a cameo by Garrett Morris, who played Ant-Man on a Saturday Night Live (1975) sketch that also featured John Belushi as the Hulk.

At one point, Nebula tells Rhodey that she's not been always like that. Rhodey answers that neither has he. This could be a nod to the character's actor replacement after the first Iron Man film, but more likely is a reference to the bionic leg braces Rhodey wears to walk since his accidental paralysis in "Captain America: Civil War" (2016), which was the second MCU movie to be directed by Joe and Anthony Russo.

When we see the young Hank Pym, he is roughly the age that Michael Douglas was when he starred in The Streets of San Francisco (1972). His hair on that show was his normal blonde color, whereas in this film it is dark brown. However it is the same exact hairstyle.

James D'Arcy, who plays Stark's butler Edwin Jarvis, is the only actor, as of yet, to go from television to the films.

An eagle-eyed fan pointed out how Brie Larson's 2023 superhero suit pays homage to the first Captain Marvel. After the surviving heroes of Infinity War learned Thanos prevented them from ever undoing his decimation by destroying the Infinity Stones, Endgame jumps ahead five years into the future and offers audiences a glimpse at how the world is trying to move forward. When viewers reunite with Brie Larson's Captain Marvel during a team meeting scene, the heroine is seen wearing a new suit with an inverted red and blue color scheme. Many suspected Brie Larson's updated costume was paying homage to the original Captain Marvel suit worn by Mar-Vell in the comics and one fan posted two photos allowing fans to compare both outfits

Star-Lord's happy reunion with Gamora is cut short when Gamora viciously knees him in the groin, making it clear she's not the same woman he fell in love with. This moment also calls back to the first time Peter and Gamora got intimate in Guardians of the Galaxy, which ended with similarly painful results.

The death of Black Widow, was highly criticized by fans and critics alike. Many felt her final decision left her arc incomplete, as they never actually knew what drove her to sacrifice herself. Others criticized the move by stating her actions were only used to push forward the narratives of the men in the Marvel Cinematic Universe, instead of herself. And almost everyone could agree that her absence from the final fight against Thanos' forces was disappointing. Still, despite the criticism, Scarlett Johansson stands behind the decision to have Black Widow killed, claiming that her death made sense. "It felt in-character that she would sacrifice herself," Johansson said in an interview with The Hollywood Reporter. "Of course for humanity but actually for her friends, for the people she loves. It was bittersweet." Johansson first learned about her character's death from Marvel Studios President Kevin Feige, who called her to tell her the news just as she was about to start production on Avengers: Infinity War.

Tony Stark makes a subtle, heartfelt reference to his late father when he returns to the New Avengers compound and gives Cap back his shield, calling back to a scene in Captain America: The First Avenger.

Thor nearly kills Thanos with the business end of Stormbreaker in Infinity War, impaling the Mad Titan. He nearly repeats that feat in the climax of Endgame, but this time Thanos proves too strong for the weapon to hit home.

The People's Choice Awards nominees were dominated by Disney and HBO's fantasy epic "Game of Thrones," E! announced on Wednesday. "Avengers: Endgame" scored seven nods, with fellow MCU films "Spiderman: Far From Home" and "Captain Marvel" grabbing multiple nominations as well. On the TV side, "Game of Thrones" led the group with eight for its final season, with The CW's "Riverdale" and Netflix's "Stranger Things" landing seven nominations apiece.

took in $2,820 at 110 locations on September 1st 2019, and $16,000 on Labor Day. The likely suggests that it is playing to a lot of mostly-empty theaters, but that there are still at least a few people who would rather see it on a big screen than go buy the Blu-ray, which is readily available as of this writing.

In an interview with Variety, screenwriters Markus and McFeely tell the audience why Endgame was codenamed Mary Lou early on. Markus thought it would be an interesting exercise to see what happens when things don't go well for the heroes, "Most of these movies have ended with a win. We wanted to see what happens to their personalities when they don't. When they very very definitively lose." "When we have tested this, with various secret audiences, they always said, 'The first part is the slowest.' We went, 'Well, we know that,' but I guarantee that if we cut it in half even if we could, when Cap picks up the hammer, the [Falcon] says on your left, it wouldn't resonate as much because you hadn't gone so dark before," McFeely continued. As all fans can recite from memory by now, "Part of the journey is the end." The writers wanted both the heroes and their audiences to be put through the proverbial wringer. Many of Endgame's reviews pointed toward that gradual buildup as something strange for these movies. It was all by design as the creative team was gearing up for that massive payoff in the third act. "We really want to make them feel that we value these characters as much as they do," Markus would follow up with. Then, McFeely would spell it out, "The watchword was 'Stick the landing.' Right? That's why the codename was Mary Lou."

David Dastmalchian, who plays Paul Rudd's gypsy-phobic cohort Kurt in the Ant-Man films, stopped by ComicBook's studio at San Diego Comic-Con and explained that he has a big beef with this one aspect of the movie. "First of all, Endgame's genius, it's one of the best movies I've ever seen, it's cinematic history, it's incredible, blah blah blah. Russos, you know you're amazing, everybody knows what an incredible film it is," said Dastmalchian. "Why did a rat have to run across the computer to pull Scott out of the Quantum Realm. Why couldn't it be Kirk, like, playing with computer. Couldn't I have just shown up for an hour, playing with the computer? That's my big beef." He added that he was joking, explaining that he loves and is friends with the writers and directors on the film.

The events of 2017's Thor: Ragnarok marked a notable shift in how the Marvel Cinematic Universe's God of Thunder was depicted compared to his earlier appearances. While the revitalization of Chris Hemsworth's character at the hands of director Taika Waititi was well-received (for the most part), it also posed a problem for Avengers: Endgame writers Christopher Markus and Stephen McFeely, as they had to depict Thor in their own special way for Avengers: Infinity War and Endgame. As McFeely recalled: "Remember, we were inheriting a Thor from Ragnarok who was very well and radically re-toned from the previous Avengers movies. So, we had to fly in Hemsworth and Taika Waititi word was getting out from Australia, 'You guys understand what we're doing with this movie?' We're like, 'No, I don't know what you mean. Are you making him an idiot? I don't understand!' Between taking more advantage of Chris Hemsworth's comedic chops and Thor speaking more like a denizen of Earth due to spending so much time with the Avengers, the God of Thunder definitely behaved differently in Thor: Ragnarok compared to his first four MCU appearances, although obviously the original spirit of the character was still intact. But for Christopher Markus and Stephen McFeely, they had their own plans for Thor and initially had trouble understanding what Hemsworth, Taika Waititi and the Ragnarok team had done to him. Ironically, while Ragnarok is the funniest of the Thor movies (and one of the funniest MCU movies overall), it's also arguably the most tragic for the main protagonist, as he lost so much in such a short amount of time. Fortunately for Christopher Markus and Stephen McFeely, they were able to take advantage of all this loss, particularly when it came to Avengers: Endgame. Markus added in their conversation with Vanity Fair: "In Ragnarok, he loses his kingdom, his father, his sister and his eyeball. We just thought about what would happen if any one of us sustained this loss and horror. You would probably get incredibly depressed and retreat from the world. That is a comedic performance with a lot of pain behind it."

Despite starring in several of the same films as him, Gwyneth Paltrow didn't realise Samuel L. Jackson had been in any Marvel releases right up until she shot a scene with him in this film. Speaking to Empire during a live Q&A, Marvel Studios boss Kevin Feige reflected on the scene that saw almost every single character unite for the funeral of a main character He explained that the scene was shot in October 2017, ahead of the release of Infinity War, with many actors unaware that several other A-listers had signed up to appear in future films. "Tom Holland [was] coming up to me, saying, 'Is that Michelle Pfeiffer? What is happening?'" Feige said, before adding: Gwyneth Paltrow [was] asking why Sam Jackson was there, and the other actors [were] jumping in saying, 'What are you talking about? He's Nick Fury! You've been in movies with him.' But it was really something special.'"

Thanos' first death in Endgame was a late idea Dealing with Thanos as a threat was big problem. "We have a villain who has the power of a god," McFeely laments. "So we're faced with telling a story where even if you don't defeat him, how do you even start?" It was producer Trinh Tran who suggested, according to McFeely, "I wish we could just freaking kill him." And that's what made sense, since Thanos' task is done. That allowed for the time jump and the drama of characters living with the consequences of The Snap, rather than the threat of Thanos and the arc of Endgame became how to make things right.

They did talk to actual quantum physicists, when addressing the idea of time travel, the writers started with google, but Markus also revealed that they consulted actual experts on quantum mechanics and time travel who confirmed that said "If it could happen, that's one of the ways it could happen." also, the sequence of the Avengers figuring out their time travel routes is pretty much a recreation of what it was like for the writers.

The writers also had some great insight into the writing of Depressed Thor and Tony Stark's death and funeral, and what moments make them choke up.

NoobMaster69 trolls Korg as he attempts to play a quiet and peaceful bout of Fortnite. But his trolling actions only serve to earn the ire of the God of Thunder. And based on this meme, the true identity of NoobMaster69 makes a ton of sense, and they definitely would not want Thor to tell their father what's going on. Loki; of course it would be the God of Mischief making his brother's life a living hell. Perhaps we'll find out the truth about Loki's identity as NoobMaster69 when his Disney+ solo series finally premieres on the upcoming streaming service. Hiddleston previously spoke about the difference between his early tenure as Loki and what he's doing for the new show, explaining to MTV News that it will be satisfying for longtime fans while exploring different aspects of the character that we have yet to see. "I know this character now. I feel that the audience knows him. And playing him -- and playing him truthfully, but presenting him with new challenges, which then I'd have to change him in different ways, is the most exciting aspect of it," said Hiddleston. "You've got his very specific gifts. His intelligence, treachery, his mischief, his magic, and then seeing him come up against more formidable opponents, the like of which he has never seen or known. I wish I could tell you what happens, but I can't." And while the show will pick up after the events of Avengers: Endgame, when Loki was still a hardcore villain and before his eventual rehabilitation, it will still explore some of his heroic aspects. "It is a constant source of surprise and delight that these films have connected with people, Hiddleston said to the Hollywood Reporter. "I knew he was a complex figure. Intelligent yet vulnerable. Angry and lost and broken and witty. I thought it was an amazing opportunity and it's grown into this network of movies. I could never have expected it."

In the scene where Scott Lang returns to his van in a storage locker, Ken Jeong has a cameo as a security officer.

Mark Ruffalo and Scarlett Johansson share a birthday, November 22. That date is also connected to several time travel films: 11.22.63 (2016) involves traveling back in time to prevent the JFK assassination, while the films Back to the Future Part II (1989) and Star Trek: First Contact (1996) were released that day, and it was also the day before Doctor Who (2005) premiered, a show that later would feature Karen Gillan.

In 2012, a handcuffed Loki briefly shapeshifts into Captain America to annoy Thor. Some time later, when present-day Steve is about to walk out of the compound with the Mind Stone in the scepter, his 2012 self sees him and immediately thinks he's a disguised Loki.

The ladies of Marvel shot showing all the female heroes sync up and come together at the same time may seem like pandering, but it was "just a chance to show off another amazing aspect of the Marvel roster, and there are just so many great female characters."

Both Avengers Endgame and X Men Days of Future Past events takes place in the same year 2023

Beat out Oscar-winning Bohemian Rhapsody, and its own predecessor Avengers: Infinity War, to become the UK's fastest-selling digital download film. According to the Official Charts Company, Endgame was downloaded 335,400 times between August 19 and August 27. Meanwhile, the Freddie Mercury biopic racked up 265,000 downloads in the same time frame back in February. Infinity War is said to have been downloaded 253,000 times. Hellboy which sees Stranger Things star David Harbour take over from Ron Perlman as the titular hero, currently occupies second place on the chart, with Shazam! in third position, Disney's live-action remake Dumbo in fourth and spy thriller Red Joan in fifth. Interestingly, Avengers: Endgame is now the only Marvel entry in the list's top five as the Brie Larson-fronted Captain Marvel drops to number six.

Dring a recent talk with Google Joe Russo explained why he and his brother Anthony don't have any regrets about their decisions regarding their final bow with Marvel Studios. Per Comic Book, Russo addressed the topic after one of the fans in attendance asked him about whether or not he and his brother had wanted to go back and edit Endgame after the fact. "If we regret anything by the end of it, then we did not do our jobs right," he began: "As we're making the film, we're shooting a year. So something we shot two months in we can watch three months later in the edit room and decide we don't like performance, we don't like the tone, we didn't get the joke right, we didn't get the emotion right and we reshoot it."

Tony figures out his time traveling model after he draws "mild inspiration" from a photo of him and Peter, in which they're holding an inverted diploma.

There has been speculation as to why Captain Marvel was given a limited role in Avengers: Endgame and the writers of the movie have finally set the record straight. Marvel writers Stephen McFeely and Christopher Markus spoke to Vanity Fair about their time working on the MCU and the build-up to Avengers: Endgame. According to Markus, the character of Captain Marvel presented problems for their plans for several reasons. "Well, she was always going to be in it but we didn't have much to go on. They had cast her and that was it. It is a tough balance to strike when you have a character that powerful who you're going to bring in, and you don't want it to seem like, well we just brought in this person who can clean the house that we couldn't clean in the previous movie. So, we had to decide on a balance between not making it feel like a cameo but not having her around so much that she solved all of the problems for everybody" McFeely also pointed out that Captain Marvel's powers had the potential to fix all of the problems in the movie, and the purpose of the story was to focus on the original members of the team. "It also wasn't the point of the movie, the point of the second movie was saying goodbye to the original six Avengers, so their stories were gonna be way up here. It was not fair to the other six Avengers to have Captain Marvel come in and solve all their problems, it didn't seem like good storytelling"

The very first time Thor and Star-Lord meet in Infinity War, the two are butting heads in a show of alpha male dominance. The ending to Endgame makes it clear that rivalry hasn't cooled one bit in the five years since.

Before the MCU, Robert Downey Jr. and Mark Ruffalo starred together in Zodiac (2007), which also starred Jake Gyllenhaal, later to be cast in Spider-Man: Far from Home (2019).

An earlier draft included a scene "where Thanos opened up a large portal on the battlefield walked up to them, and tossed 2012 Captain America's head on the floor."

Between Avengers: Infinity War (2018) and "Avengers: Endgame", there are two Infinity Gauntlets: one created by Eitri (Peter Dinklage) and one created by Tony Stark. Dinklage also appears on Game of Thrones (2011), which also features a family named Stark. His character in X-Men: Days of Future Past (2014), based on another Marvel property, is named Trask, which is an anagram of Stark.

One reason behind the five-year-jump is that "it allows all those characters to get really close to being 'quote-unquote' complete people."

Jeremy Renner and Elizabeth Olsen also starred together in Wind River (2017).

Michael Douglas and Robert Downey Jr. previously appeared together in Wonder Boys (2000), which also featured a previous Spider-Man, Tobey Maguire. Douglas also appeared with Don Cheadle in Traffic (2000) (along with fellow MCU veterans Benicio Del Toro and Miguel Ferrer) and Gwyneth Paltrow in A Perfect Murder (1998).

YouTuber Shinya Kogami, studied each minute of the two films and tabulated how many seconds each major character earned, with Tony Stark's total being 3,001 seconds, which is roughly 50 minutes, while Thanos only earned 2,272 seconds, which is roughly 38 minutes. Check out the full breakdown of each character's screen time above. Interestingly, one of Iron Man's signature lines in the films is, "I love you 3000," with Kogami noting in their description, "I wanted to manipulate the data to show 3000 but that would be not the right thing to do, so I have left it as it is." When focusing solely on Infinity War, the data shows a different story, as the villain earned 25 minutes of screen time, with Gamora earning 17 minutes and Tony Stark earning 16 minutes. Combined, the two films have a run time of five hours, with this data confirming just how sprawling of an adventure these films were.

The Ancient One forces Bruce into an out-of-body experience exactly like the one Stephen Strange experienced when he first encountered the Sorcerer Supreme.

When we first see Howard Stark in the Camp Lehigh sequence, he's wandering the lab calling out for "Arnim." This is a subtle reminder that Arnim Zola worked for SHIELD after WWII, setting the stage for one of the key scenes in Captain America: Winter Soldier.

When Tony relays some of his father's helpful advice to his father, Howard inadvertently calls himself "a smart guy." Tony responds with "He did his best," which calls back to an early scene in Captain America: Civil War. Tony's BARF system shows a younger, digitized version of himself telling Howard, "I know you did your best."

Iron Man and Rescue take center stage in a shot where the two characters stand back to back and unload a huge arsenal against Thanos' forces. This is similar to a scene in Iron Man 2 where Iron Man and War Machine make their final stand against Whiplash's drones.

A conversation between Scott and Hope during Ant-Man and the Wasp is referenced during the final battle.

Vanity Fair spoke to Stephen McFeely and Christopher Markus. It was there the screenwriters broke down how they went about dissecting the film's big deaths. "I think really all we were handed was Thanos, which necessitates the use of the Infinity Stones - which are this, this, and this throughout the MCU - and 'if you want to get rid of people, you can, but you're under no obligation to just kill them willy nilly.' And that was just about all," Markus said. Of course, the pair did not decide to kill people on a whim. McFeely stressed their decisions were not made randomly, but they did need to figure out which characters would even be in the film to axe. "There were a bunch of obvious implications from that," Markus said before adding, "Namely, we could bring in the Guardians, because two of Thanos' stepdaughters were on that ship. It could be anybody from anywhere, and in fact should be."

Markus and McFeely revealed to Vanity Fair that not only did Kevin Feige want Infinity War and Endgame to function as their own stories, but also that the studio didn't really care much about whom they killed. Markus kicked things off, saying: "It was always going to be Avengers 3 and 4. It was always intended to be two separate movies. That was from on high from Kevin [Feige]. He did not want to make a two-parter. Very different structurally and tonally, and that was always our intention." Piggybacking off his co-writers comments, McFeely revealed that the gig just kind of happened and that there was no initial offer. "I remember no one from Marvel ever asked us to write these movies. Kevin never called and said 'I want you guys to write these.' We just started negotiating." They had plenty to draw from and Marvel gave them plenty of freedom. The only thing the studio asked for was a Thanos-focused conflict. Christopher Markus said: "I think really all we were handed was Thanos, which necessitates the use of the Infinity Stones -- which are this, this, and this throughout the MCU -- and 'If you want to get rid of people, you can, but you're under no obligation to just kill them willy nilly.' And that was just about all." To avoid confusion (and to avoid having his comments misconstrued), Stephen McFeely clarified: "This is not to say we picked people at random to kill." Markus revealed where his head was at when working certain characters into the final two movies. "And there were a bunch of obvious implications from that. Namely, we could bring in the Guardians, because two of Thanos' stepdaughters were on that ship. It could be anybody from anywhere, and in fact should be."

Writing a screenplay is just as hard and messy as any other writing The Markus-McFeely process sounds pretty much like most other writers. There's lots of outlining, there's a focus on structure, which Markus called "a framework so you don't dive into despair." Then a slow back and forth between the writers as they hack out pages and produces a "Frankenstein draft" that eventually will be edited into a function first draft. The process for screenwriters however never stops until the film in in theaters, with re-writes and changes happening during and even after shooting.

Writing Captain Marvel was particularly difficult, The fact that Endgame shot before the Captain Marvel solo film was even written was a huge hurdle, as was the extent of Carol's powers. "It is a tough balance to strike when you have a character that powerful," Markus explains. "You don't want it to seem like you just brought in this person who can clean the house that you didn't clean in the last movie." The writers note that Endgame was about wrapping up the stories of the original six Avengers, and that having Carol solve all the problems wouldn't be satisfying for that story so the character was less emphasized. They also had the same problem to some extent with T'Challa in Infinity War, who was there, but not the focus.

The Benatar resembles a swallow in the contre-jour shot where it is drifting around in space. Being a monogamous migrating bird, swallows are a symbol for loyalty, hope, and the safe return home after a long journey. Thanks to Captain Marvel, Tony and Nebula make it back home in one piece.

After delivering the highest-grossing movie of all-time (NBD), nobody would've blamed Joe and Anthony Russo for shutting it down for the rest of the year and taking an extended vacation/victory lap. Instead, they're currently in Toronto promoting the first film produced by their newly-formed studio AGBO, Mosul. Shot entirely in Arabic, the film's an intense war movie about the Ninevah SWAT team, an elite Iraqi police force locked in a desperate fight against ISIS in the war-torn city, and features a cast of relative unknowns, a far cry from the A-list ensemble the Russo Brothers assembled for Avengers: Endgame. It's also based on a true story, adapted from a 2017 New Yorker article called, fittingly enough, "The Avengers of Mosul." There's a more concrete Avengers connection here too: The article was first brought to the Russos' attention by Endgame (and Avengers: Infinity War and Captain America: Civil War and Captain America: The Winter Soldier) screenwriter Stephen McFeely, who's a partner in AGBO along with his co-writer Christopher Markus. "While we were all still executing Infinity War and Endgame, we would talk a lot about it on set -- thinking about what should be our first project," Anthony Russo explained to SYFY WIRE when we sat down with the brothers, as well as Mosul's Iraqi executive producer Mohamed Al-Daradji, at TIFF. "Steve brought us this article and said, 'This is the most amazing article I've ever read,' and we agreed with him. It moved us really profoundly." And even though they were in the middle of the massive years-long production that was Endgame, they didn't want to wait to get started. "We felt a real sense of urgency that not only does this story need to be told, but it needs to be told ASAP," Anthony reasoned. "Because the conflict was still going on." (And is still going on to this day.) That meant cashing in on their Marvel cred immediately in order to get Mosul off the ground. "There's no other film company that would've made this film," Anthony argued. "From the very beginning, it was a challenge to Joe and I to do everything that we could to try to shepherd this movie through the system properly, because I don't know that anybody else ever would've." It also meant deciding to shoot the film in Arabic, part of an effort to make the film as authentic as possible, to tell this story from an Iraqi point of view. Enter Al-Daradji. "I came on board when I read the script that Matthew [Michael Carnahan] wrote. It was actually one month after the liberation of Mosul, and it was very emotional to read. Because I was just there a couple months earlier," Al-Daradji said. "It was very important to me to be a part of this process and to work with the whole team." "Look at photos of Mosul: the level of destruction is staggering. Staggering and almost incomprehensible," Joe Russo said. "So the intent here was to bring audiences into that world in a way that allowed them a window into the pain and the suffering, and the fight for human dignity that was happening in that city." To some, it may seem like a bit of a left turn to go from superheroes to Iraqi soldiers, but the Russos don't see it that way. "We've had a really varied career. A lot of people are heavily skewed toward our Marvel work, but we started as very low-budget, independent filmmakers," Anthony explained, saying the brothers also grew up with a keen interest in politics and international affairs. "We tried to imbue our Marvel work with a strong international sensibility, and a lot of world politics and world issues. So for us, it feels like a natural extension." "We love that level of filmmaking that Marvel afforded us. We love telling stories on that level, but we're also fed by smaller stories and more specific stories," he continued. "So for us moving forward, it's moving back and forth between the two." Which is why, even though Endgame closed the Russos' Marvel chapter for now, that door isn't shut for good Asked what it might take to bring the brothers back to the MCU, it sounds like the recent Fox merger offers plenty of enticing possibilities. "I grew on up [John] Byrne's X-Men run. Ben Grimm was a favorite character growing up, The Thing. And Fantastic Four is now in the Marvel fold. There's a lot," Joe said. "Silver Surfer is an amazing character. Going really big in cosmic would be a lot of fun. So there's a lot of things that could attract us."

When the Avengers confront Thanos on his retirement planet, they discover that Thanos destroyed the Stones and that doing so nearly killed him. Five years later, Tony snaps his gauntlet to destroy Thanos and his army, but since Tony is not as strong as Thanos, he is killed by the power of the Stones. Tony's knowledge of this reinforces his Heroic Sacrifice since he was aware of the cost but did it anyways.

A subtle example is Professor Hulk; who has "the brains and the brawn together" (brains = Banner, brawn = Hulk). Eventually, those traits allowed him to perform the reverse-snap, since one requires both physical strength and brainpower to snap with the gauntlet.

On Monday, September 9th, Endgame went into the 137th day of its box office run, only showing in 55 theaters. Monday marked the first time that Endgame made less than one-thousand dollars in a single day, with the Marvel blockbuster only bringing in $940. Granted, with a nearly $2.8 billion run at the box office thus far and the title of the highest-grossing film of all time, it's safe to say that this smaller gross is essentially a drop in a bucket. "Somebody wrote recently that for the first time in 45 years, the highest-grossing movie ever was not directed by [Steven] Spielberg, [James] Cameron or [George] Lucas." co-director Anthony Russo said of the film's box office performance. "Those are all our heroes; those are all people [who] we grew up watching their movies, and studying their films to learn how to become filmmakers, so it's weird. It's hard to process."

In May, Anthony and Joe Russo's "Avengers" flick edged out "Titanic" for the second spot on the list, having earned $2.2 billion at that point. Come July, "Endgame" surpassed "Avatar." Now, the second-and-third-place director -- notorious for his cocky attitude -- is speaking out about his losing his box office crown. However, the measured response from the guy who infamously bellowed "I'm the king of the world!" at the 1998 Oscar telecast might surprise some. "It gives me a lot of hope," the filmmaker told Deadline Wednesday. " 'Avengers: Endgame' is demonstrable proof that people will still go to movie theaters." Cameron, who's currently working on back-to-back follow ups to "Avatar" in New Zealand, said he hopes the enthusiasm for "Endgame" transfers over to his new sequels -- when they're ready. "The thing that scared me most about making 'Avatar 2' and 'Avatar 3' was that the market might have shifted so much that it simply was no longer possible to get people that excited about going and sitting in a dark room with a bunch of strangers to watch something," he told the entertainment outlet.

Making Steve Rogers look like an old man was no easy for the Russo's and their VFX team. Luckily, the team had some solid reference in methods used on Captain America: The First Avenger (2011) to help them pull off the look of Steve Rogers, a new character having lived an entire life and growing into an old man. "We then started casting for a skin double, looking around for an old guy who approximates the same face and age of Cap, or what Cap would be," Jen Underdahl, Marvel's visual effects producer said. "We shot in the same lighting conditions right after Chris performs. He gives the same lines, he tries to emulate Chris' performance as much as possible so it doesn't take a whole lot of hammering when you put it on Chris' face." Then, another actor had to step in or sit in for Captain America actor Chris Evans. "In addition to the skin double, you also need to give him an older man's body, an older man's sort of overall profile," Underdahl said. "To do so, we'll do an overall warp on his body and literally squish him down so he fits in the plate as this character." This is where the technology used on the first Captain America movie from 2011 came in handy. "We did the same sort of thing though not with as heavy a hand with old Cap. They took some neck off of him, so he wasn't quite as beefy here, and we shrunk his shoulders to give him that 106-year-old super soldier look."

Director James Cameron is actually pretty psyched there's a new king of the film world. Cameron's Avatar was dethroned by Avengers: Endgame as the highest-grossing movie of all time in July after a decade at the top. But the filmmaker, who also previously held the box office record for Titanic, told Deadline on Wednesday that Endgame's stunning accomplishment actually brought him "a lot of hope." That's not just him being a good sport; Cameron explained the movie's success put him at ease about today's movie-going environment as he prepares to release not one but four Avatar sequels. "Avengers: Endgame is demonstrable proof that people will still go to movie theaters," Cameron told Deadline. "The thing that scared me most about making Avatar 2 and Avatar 3 was that the market might have shifted so much that it simply was no longer possible to get people that excited about going and sitting in a dark room with a bunch of strangers to watch something. ... I'm happy to see it." Of course, Cameron is suggesting this means Avatar 2 can knock Endgame off its perch when it thunders into theaters in two years; the director offered a "who knows" about whether his sequel can be as successful as its 2009 predecessor, but he said it's certainly "possible."

During an interview with SyFyWire about their next project after Endgame (they're directing an R-rated film called Mosul about an elite Iraqi police force), the Russo Brothers revealed what it would take for them to direct another Marvel movie. Joe Russo said he and his brother really enjoyed telling stories over the course of a number of movies instead of telling an entire story in one movie when they directed four movies for Marvel Studios. "I think after you go on the journey that we went on because there is a comprehensive narrative, an overarching story from Winter Soldier [Captain America: The Winter Soldier] all the way to the end of Endgame [Avengers: Endgame] that involves Tony and Cap, through Civil War [Captain America: Civil War], through Infinity War [Avengers: Infinity War] I think that scale of ambition in storytelling is a bug that's bit us," he said. "And we're compelled to tell more stories on that scale, with that sort of years-long ambition to them," he added. Joe Russo also said they may return to the MCU if they got the opportunity to direct their favorite superheroes growing up. "I grew on up [John] Byrne's X-Men run. Ben Grimm was a favorite character growing up, the Thing. And Fantastic Four is now in the Marvel fold. There's a lot," he said before adding, "Silver Surfer is an amazing character. Going really big in cosmic would be a lot of fun. So there's a lot of things that could attract us."

In an interview with Wired, Marvel Entertainment's visual effects producer Jen Underdahl revealed that the rat wasn't actually, as you might expect, a digital effect: it was a real, professionally trained rat. According to Underdahl, visual effects supervisor Dan DeLeeuw made a bet with a line producer that they could find a trained rat to perform the sequence, and the line producer kept insisting the rat would have to be digitally replaced. Guess who won. "For those of you who are curious, that is not a digital rat," Underdahl said. "For all the things that we do and for all the things that we replace, that is actually a practical acting rat. I don't have his name, but he's really there." The rat emerged as the surprise hero of Avengers: Endgame, one that director Joe Russo and writer Chriostopher Markus even joked about on the film's commentary track as being "the hero of the Infinity Saga." It was a fluke moment, but one that set in motion a chain of events that led to the Avengers bringing half the universe back from extinction. There's even a fan theory that the rat was Loki in disguise, because no one could believe that some dumb rat walking on a remote was part of Doctor Strange's "1-in-14 million" chance of them actually beating Thanos.

All of the Quantum Realm suits worn in "Endgame" are VFX creations because the film's production had to start before the costume design team could finalize what the suits would look like. "Endgame" VFX producer Jen Underdahl reveals as much in a WIRED documentary about the extensive special effects work that went into the Marvel movie (via ScreenRant). "Endgame" was shot back-to-back with "Infinity War" and the production had a tight schedule in order to meet the film's April 2019 release date. Waiting for the costume designers to finalize the suits was not an option. "The time suits are a combination of Ant-Man, Tony Stark, and Guardians tech. That took quite a while for us to land on," Underdahl said. "By the time we got a final version, we were already in principal photography. We knew we were going to build them anyway, since they had to 'nano' on and off with Tony's tech, and it ended up being that the costume department didn't have time to develop, fit, and fabricate all the costumes for those hero characters, so we ended up doing them digitally." The VFX team also had to digitally create Captain Marvel's full costume any time the Brie Larson superhero appears in "Endgame." Larson shot her scenes for "Endgame" because she was starting production on her standalone "Captain Marvel" movie, so the costume designers on that film were still figuring out the specifics of her costume when production on "Endgame" got underway. "Her suit, every time you see it in the movie, when she's in her full costume, is digital. Again, the designs for those suits were not ready in time for us to photograph Brie. When you saw her at the beginning, as she's rescuing Tony Stark, when you see her come back, when she's talking to Nat in the Avengers compound, with Rocket and Nebula, and then in the final battle when she comes back and kind of saves the day, that's all the digital suit." Creating digital costume is one of the reasons "Endgame" contains more VFX shots than most contemporary comic book films. The decision to use CGI costumes speaks to Hollywood's larger production trends on tentpoles, where release dates are set in advance and any delay in filming could be a nightmare for release.

Thor and Captain Marvel are easily two of the most powerful characters in the Marvel Cinematic Universe. But one question remained unanswered: Who is more powerful? co-director Joe Russo thinks he knows. In a special segment on the Digital HD release, Russo explains Captain Marvel is probably the more powerful of the two. "It's interesting seeing the Avengers with Captain Marvel," Russo states. "I think that she dimensionalizes them in a really great way. Just from a pure power standpoint and what her abilities are. If you're talking about a collection of heroes, and you're gonna go face Thanos, who we believe still has the gauntlet. She is as powerful, if not more powerful than Thor, and you suddenly have hope again. Because they all know what happened at the end of the last movie, he walked through them like they were paper."

At the Camp Lehigh Army base in 1970, as Tony stumbles into the underground bunker in search of the Tesseract. In the background, there are rows of green computer screens. While it's almost impossible to make out what the screens depict, the VFX reel reveals that, in the distance, is a display of Arnim Zola's face.

A keen-eyed Redditor caught that, during Captain Marvel's blitz on the Mad Titan, she plants her boot firmly in his left palm, to prevent him from closing the fist wearing the Infinity Gauntlet. Of course, at the time, the Avengers were unaware that Thanos had "used the Stones to destroy the Stones," so their attack was coordinated around exploiting the one weakness of the most powerful weapon in the galaxy.

Visual Effects Producer Jen Underdahl detailed how she approached Brolin's Thanos in both Infinity War as well as this film, reflecting on how Josh Brolin's performance was as much a character discovery for the team as it was a technical journey one that led the team to change how Thanos was written due to Brolin's performance choices. "Not only was it a technical discovery for us, it was also a character discovery for Josh [Brolin], Joe and Anthony [Russo]," she explained. "We found... we kind of had imagined Thanos as this big, mean, you know -- over the top character, but how Josh played him was beautiful. His performance was menacing but subtle. Terrifying, but in little flinches, so we realized at that moment that we really needed to have a company that captured all that and pulled his performance through the prosthetics so that when you are like this on Thanos [shows a shot of the Avengers villain], you felt the terror in your bones with this character, because, you had to."

A comment from Ant-Man about Captain America's ass proved one of the most hilarious parts for many viewers. However, the line almost didn't make it into the film. During the Vudu Viewing Party for Endgame, Marvel Studios President Kevin Feige revealed, "Ant-Man's line, 'As far as I'm concerned, that's America's ass,' was not in it for quite a while. I think it was [executive producer] Louis D'Esposito or someone who said, 'What happened to that funny line about America's ass?'" "We're like, 'Is it funny? I don't know, let's try it in the next test screening,' because we screen all of our movies multiple times for audiences. And it killed, it killed instantly, without question. And it stayed in the movie, and later in the movie it a got a reprise in some additional photography where Cap himself comments on his own ass." "We questioned, let's be honest, we questioned, 'Is it in character? Is it in the character of Steve Rogers to make a comment on his own ass?' And the thought was, yes, it works, and the audience likes it," Feige said. "But also, we were building a version of Steve who actually was growing, and who was loosening up, and who was leading towards the decision [to retire]. It was part of a character shift, maybe we're just justifying the laughs, but it was part of a character shift to get to the decision he makes at the end of the film to stay with Peggy and get some of that life Tony was always telling him to get."

An extra that appears towards the end of the film appears to be dressed in Spider-Gwen colors.she appears 2 hours and 35 minutes into the film, during the scene where Peter Parker reunites with his best friend Ganke Lee. The extra, who walks by the two Spider-Man characters on the left, sports a blue denim jacket, a light pink backpack and a black skirt with a webbed pattern. Her blonde hair is pulled to the side, in the semblance of an under-shave like Spider-Man: Into the Spider-Verse's version of the character.

Writers Christopher Markus and Stephen McFeely expressed their belief Steve Rogers travelling back in time to live with Peggy Carter would not have created an alternate timeline. This prompted a lot of fan speculation about where else the character might have appeared, with some speculating an older Steve might have appeared at Peggy's funeral in Captain America: Civil War. Markus has now reacted to that theory, though he doesn't confirm or deny it. In an interview with the Los Angeles Times, Markus reacted to the theory, saying, "I would very much like that. There is no set explanation for Cap's time travel. I mean, we've had public disagreements with [directors Anthony and Joe Russo] about what it necessarily means [laughs], but I love the idea of there being two Steve Rogers in the timeline. One who lived a long life with Peggy and is in the background of that funeral scene watching his young self carry his wife's coffin up. Not just for the time travel mumbo jumbo of it, but for the just weird, personal pain and satisfaction that would be happening between two Steve Rogers there. I kind of love it." Although Markus and McFeely do not believe Steve created an alternate timeline when he went to the past to live with Peggy Carter, directors Joe and Anthony Russo dispute that take, explaining the rules of the movie's time travel mean Steve must have created an alternate timeline. Markus and McFeely, for their part, claim Steve is actually the father of Peggy's children.

The special effects team says that Cap was aged 106 years when he returned to 2023 to give Falcon a new shield and make him the new Captain America: Cap is born in 1920. He goes in the ice in 1945 (25 years old) He is found in 2011 and lives on till 2023. (12 years) This makes Cap (before he returned the stones) 37 years old. This means he spends 69 years with Peggy. (106 - 37) Assuming he returned to Peggy in 1947, a good 2 years after the war ended, he would live till 2016 in alternate timeline. (2016 - 1947 = 69). 2016 is when Peggy died (in Captain America: Civil War) This also proves that Cap returned to main timeline shortly before he time traveled for his dramatic entrance.

The major wrinkle of taking the Infinity Stones creating multiple timelines is addressed at the end of Avengers: Endgame, with Steve Rogers returning them - along with Mjolnir - back to their original time periods. Assuming Cap does this correctly (as implied), that means the actions surrounding the Reality Stone in Thor: The Dark World, the Space Stone in 1970, the Mind Stone in The Avengers, the Time Stone in 2012 and the Soul Stone in 2014 are all reverted to normal: he erases the timelines created by their removal. The question of how exactly Steve returned the Soul Stone, or his reaction to Red Skull being its guardian, is left to audiences' imaginations. What that does leave is a pretty startling implication: this always happened. Rocket always stole the Aether from Jane, Howard Stark always bumped into grown-up Tony on the day of his son's birth, the Ancient One always talked to Banner four years before her death. It's a linear timeline and all of this was going on in the background of the MCU all along. While that's a retcon by anyone's reasoning, it is rather tight; none of the mentioned past-future interactions directly contradict the timeline.

Michael Douglas and the Russo Brothers previously worked together on You, Me and Dupree (2006).

This is the first all-time highest-grossing movie to be filmed with IMAX cameras, particularly with ARRI Alexa IMAX cameras.

They allow themselves coincidences in Act I, but "coincidences late in the movie are lazy." So yes, they're okay with the rat helping release Lang from the Quantum Realm.

The Russo Brothers were asked why none of the Nova Corps, who were seen in Guardians of the Galaxy (2014), showed up to fight Thanos at the end of Endgame. "Look closely at that scene again," Joe Russo said. "You will see Richard Rider in the background of a shot. Easter egg." Rider, of course, is better known as his superhero name Nova, a very popular cosmic Marvel character who has long been discussed as a worthy addition to the Marvel Cinematic Universe but, as of yet, has not been. The io9 team quickly went to work, "grabbing every image of the final battle of Endgame we could find. Went frame by frame through the digital copy. Enhanced images using the best and most powerful technology imaginable. We're talking CIA shit. Blade Runner shit. The best. And the results? Well, shocking isn't quite strong enough. We'll let the images speak for themselves."

Tilda Swinton had previously collaborated with writers Christopher Markus and Stephen McFeely in the Chronicles of Narnia films - one of those films also featured Peter Dinklage, who also appeared in Avengers: Infinity War (2018) (also written by Markus and McFreely).

Scott Lang's storage unit number is 616. Which, fun fact, is the same number used for the primary continuity (Earth 616) of the Marvel Comics Universe.

The Russo's call the game of keep-a-way with the gauntlet the "flea flicker"

Steve Winwood's "Dear Mr. Fantasy" is the needle-drop over the opening Marvel credits, and they chose it both as a way to distinguish this as end of an era but also to speak directly to the idea of Marvel as a giant pop culture factory.

When the Avengers track down Thanos on his retirement world, the wounded Mad Titan is held down by several heroes at once. This moment replicates a similar scene in Infinity War, as Iron Man and his allies try to wrangle the Infinity Gauntlet off of Thanos' arm.

Thor isn't the only Asgardian who has no idea what a raccoon is. After Rocket is discovered by a group of Asgardian guards in 2013, he flees while one of them shouts "Get the rabbit!"

Frank Grillo and Maximiliano Hernandez also appeared together in Warrior (2010) and Pride and Glory (2008).

Ridley Scott's Black Rain (1989) was a visual influence on the Tokyo-set introduction of Hawkeye as assassin.

CNN news ran a story that a man hopes to set a record by watching 'Avengers: Endgame' over 110 times.

The man in the black suit at the base is played by writer Christopher Marcus.

The Avengers each wore one of the white and red time travel suits so they could shrink down to size and move through time in the Quantum Realm. Most fans have noticed how similar the designs are to Hank Pym's Quantum Realm suit from Ant-Man and the Wasp. But in a new interview with Wired, Visual Effects Producer for Marvel Entertainment Jen Underdahl recently revealed how Guardians of the Galaxy Vol. 2 originally played a part in the design of them. She revealed never before seen pre-viz that had the helmets of these suits be entirely made of the breathable mesh tech that the film used. This may just be pre-viz of what these helmets could look like, but it became clear early on that this would not be a suitable design for the movie. Directors Anthony and Joe Russo decided that these helmets would not work even when this design was done. From that point on, Underdahl and her team retooled the look and gave each suit - which were 100% digitally made - the Ant-Man-esque helmet that Avengers: Endgame features. Even though this is a quick and early look at these helmets, there's no question that the final masks that were chosen were the best way to go. These breathable mesh helmets simply do not work with the rest of the suit. That said, Underdahl's team did still incorporate a piece of the mesh into the final designs, as it serves as the visor in the helmets.

Unused concept art shows thatValkyrie and Okoye would've swapped weapons during the final battle, so Okoye would've wielded Valkyrie's sword, and in turn she would've used the former's vibranium-tipped spear. The scene was designed to show that the two are so skilled in combat it doesn't matter what or whose weapon they're using, but it's not too hard to see why it was cut. The scene involving Cap and Thor, with the former lifting Mjolnir, needed to seem special, and this weapon-swapping might've been a bit too repetitive to work.

Concept art shows Captain America unsure if he can actually lift Mjolnir, with Thor's hammer lying on the ground in front of him, rather than flying straight into his hand. This fits with the common belief of Steve Rogers not being worthy as seen in Avengers: Age of Ultron, and works with his own belief that he might not be. However, the Russos have said Captain America was always worthy, and their presentation of the scene works better with that idea, and gives a more epic presentation of it.

The final battle is already very long, but it was almost even longer, and would've included a scene where many of the superheroes involved pause for breath and begin to strategize what their next moves will be, it would've included many of the biggest characters, including Captain America, Spider-Man, Star-Lord, and Iron Man. The scene ran for approximately three minutes, which is quite a long time to pause the action for a break in the trenches, and that's ultimately why it was cut. Writer Stephen McFeely said: "It didn't play well... When you have that many people, it invariably is, one line, one line, one line. And that's not a natural conversation."

Where is Gamora?" may be an Infinity War gag, but it is one of Avengers: Endgame's biggest questions, and one that it leaves behind at the end of the film, likely setting up Guardians of the Galaxy 3. But while audiences simply had to assume she'd left the battlefield at some point, this Avengers: Endgame deleted scene confirmed it - and had a poignant tribute to Tony Stark to boot. Coming at the point when Tony dies because of the snap, it sees every MCU hero assembled there taking a knee one-by-one in tribute to Iron Man, before cutting to Gamora, who quietly walks away. It fills in a key mystery and is touching, but at the same time it performs the same function as the even better funeral scene that comes not long afterwards, so it's easy to see why it was cut

The Avengers carefully chose what times to visit based upon the ease with which they could access an Infinity Stone. That clearly means that something must have happened in 2009 that involves an Infinity Stone. At that time, the Reality Stone was still hidden in the ancient vault constructed by Thor's grandfather, Bor; the Power Stone was inaccessible, with the Temple of the Power Stone on Morag submerged until the tides receded in 2014; Thanos still had possession of the Mind Stone, and the Soul Stone was secreted on Vormir, which could've been picked up at any point. This can only be connected to the Tesseract then. The question is a simple one: What happened to the Tesseract in 2009? It's known to have been in SHIELD's possession since 1995, when Goose coughed it up on Nick Fury's desk in Captain Marvel's post-credits scene. According to tie-in comics, such as Fury's Big Week, Fury himself refused to devote resources to researching the Tesseract. It's possible that he believed its powers were too great, and was wary of drawing another alien invasion after the events of Captain Marvel. Whatever the reason, though, Fury shelved the Tesseract project for some time. It wasn't until the late 2000s that the World Security Council began to pressure Fury into focusing his attention on the Tesseract once more. The arrival of Asgardians on Earth in Thor persuaded Fury he had to change his priorities, and he swiftly recruited Erik Selvig to work on the Tesseract as part of a reactivated Project PEGASUS. It's possible, then, that the Tesseract was moved in 2009 - taken back to Project PEGASUS, at the World Security Council's bidding. If that's the case, the Avengers would probably be aware of it; Tony Stark reviewed the history of the Tesseract as far back as The Avengers, although the file is sure to have been redacted so as not to mention Kree and Skrulls. It would be easier to steal the Tesseract during transport than to break into Project PEGASUS, so this time period would naturally become of interest. In the end, however, the Avengers realized that no less than three Infinity Stones were in New York in 2012, so they dropped the 2009 plan altogether.

All 36 heroes during the final battle: Iron Man - Marvel Studios' first superhero, Tony Stark saves the universe as Iron Man one last time in Avengers: Endgame by solving the issues of time travel and using the Infinity Stones to wipe out Thanos and his army. Captain America - As the first Avenger, Captain America fulfills his duty that began decades before. After becoming worthy of wielding Mjolnir, Steve Rogers returns to the love of his life in the 1940s/1950s. Thor - Considered a failure at the start of Avengers: Endgame, Thor, aka the God of Thunder, finds the courage to face Thanos once again in the final battle and help defeat the Mad Titan once and for all. In the end, Thor understands what it truly means to be king... by not being one anymore. Hawkeye - In the years since losing his family in the Decimation, Clint Barton leaves behind his identity as the superhero Hawkeye and becomes Ronin, hunting down cartels and gangs around the world. But the hope of seeing his family again brings him back into the fold. Hulk - After Infinity War, Bruce Banner spent 18 months figuring out how to merge the brains and the brawn together to create Professor Hulk. And he becomes vital to not only figuring out time travel but also making sure that they don't doom the universe by creating alternate timelines. Falcon - Falcon returns to fight alongside Captain America one last time in Avengers: Endgame's final battle after first being dusted in Infinity War. His voice is the first one audiences hear after the snapped victims return. Of course, his first line is, "On your left" - a reference to Steve Rogers' line from Captain America: The Winter Soldier. War Machine - Col. James Rhodes became War Machine in Iron Man 2 and fought alongside his best friend, Tony Stark, in that film. And he had the opportunity to do so one more time in Avengers: Endgame, while also having the experience of time traveling in outer space! Scarlet Witch - Appearing first in Avengers: Age of Ultron as an adversary, Wanda Maximoff eventually became one of the Avengers' strongest heroes, with her superpowers coming from the Mind Stone. And now, she's set to appear in her own TV series, titled WandaVision. Ant-Man - If it wasn't for a rat, Avengers: Endgame's story wouldn't be possible, and time travel itself wouldn't have happened without Scott Lang, who returns as Ant-Man (and Giant-Man) in the movie's final battle. Ant-Man also represents the audience in this film - and for good reason. Wasp - Hope van Dyne returns after the snap is reversed, and she wastes no time in getting in on the action as Wasp, even telling "Cap" that she and Ant-Man have the task of getting the Quantum Tunnel up-and-running covered. Wasp became the MCU's first female leading character in Ant-Man and the Wasp, and that legacy is continued in Endgame. Spider-Man - As one of Marvel's fan-favorite characters, Peter Parker came back from his emotional send-off in Infinity War as Spider-Man (or, more accurately, the Iron Spider). While everyone's future is up in the air, Spider-Man is at least coming in another movie this summer: Spider-Man: Far From Home. Star-Lord - Redeeming himself after his fateful moment in Infinity War is Peter Quill, aka Star-Lord, who's now trying to hold onto his team while also searching for the person he lost to Thanos - Gamora. Nebula - Perhaps the most underrated character in Avengers: Endgame and the unsung hero in the fight against Thanos, Nebula returns not once but twice in the movie's final battle - once as her present self and another as herself from 2014. And she's, unfortunately, forced to kill past self in order to protect her sister. Gamora (2014) - Gamora was killed in Infinity War, and that death cannot be undone, just like Black Widow's death. But Avengers: Endgame brings the past's Gamora into the future and sets up her story for Guardians of the Galaxy Vol. 3. Drax - Drax the Destroyer has had one mission: kill Thanos. While he tried and failed to do so in Infinity War, he managed to complete his task in Avengers: Endgame's final battle by aiding his fellow superheroes. Now, his path is open, just like Thor's. Rocket - Rocket was one of the last surviving Guardians in Avengers: Endgame, and when Thor was down on his luck, it was Rocket who stepped up and helped the Avengers succeed in bringing everyone back. Groot - Groot has died twice since first appearing in the MCU in Guardians of the Galaxy - the first time as a sacrifice and the second time as part of the snap - but he was reunited with Rocket in Avengers: Endgame's final battle, and they battled Thanos' army together. Mantis - Mantis is one of the newest members of the Guardians of the Galaxy, but her powers came in handy in Avengers: Infinity War, and they undoubtedly helped some more in Endgame's final battle. Perhaps she'll be able to use her powers to help Gamora (2014) learn about her other self. Doctor Strange - Just like Ant-Man, Avengers: Endgame wouldn't have been possible without Doctor Strange, whose plan was put in place when he gave up the Time Stone in Avengers: Infinity War. While he didn't have too much to do in Endgame's final battle, he knew exactly what needed to be done in order to make sure they won - and they did. Wong - While Doctor Strange was coming back from Titan, Wong took it upon himself to unite the world's heroes and bring them to the Avengers HQ for the final battle against Thanos. Black Panther - In an exciting moment, Black Panther is the first major hero to return after the snap, and he was crucial to getting the Infinity Stones where they need to go. It's clear that, as the king of Wakanda, Black Panther's role in the MCU is only going to get bigger from here on out. Okoye - Okoye was the only major Black Panther character who wasn't killed by the snap in Avengers: Infinity War. She continued to coordinate with the Avengers in the five years since the Decimation, and when the time was right, she brought everyone from Wakanda to the Avengers HQ to fight Thanos and his time-traveling army. Bucky - No longer the Winter Soldier, Bucky Barnes became the White Wolf in-between Black Panther and Avengers: Infinity War, and he was perhaps the only person wielding a traditional weapon in Avengers: Endgame's final battle. Valkyrie - Valkyrie was a disgraced hero in Thor: Ragnarok, but after redeeming herself, she lived up to her name in Avengers: Endgame's final battle. And now she's been promoted to the queen of Asgard. Captain Marvel - Coming on the heels of her solo movie, Carol Danvers helped save the Avengers twice in Endgame - the first time by saving Tony Stark and Nebula and the second time by singlehandedly destroying the Sanctuary-II. Then she took on Thanos by herself. Needless to say, Captain Marvel is now one of the strongest heroes in the universe. OTHER HEROES include Letitia Wright as Shuri in Black Panther Shuri - Shuri was one of the surprise snap victims, as her fate wasn't revealed until the first Avengers: Endgame trailer. But she came back with her signature hand cannons and fought Thanos alongside her brother, T'Challa, in the movie's final battle sequence. M'Baku - One of the breakout characters from Black Panther, M'Baku didn't survive the snap, but he did help his king lead the armies of Wakanda against Thanos and his army in Endgame's big battle sequence. Pepper Potts - Pepper Potts has been Tony Stark's rock since the very beginning, and she finally had the chance to use her gift from her husband to fight alongside Iron Man in Avengers: Endgame's final battle. But, sadly, it was also the last time that she saw Tony alive. Korg - Korg and Meik survived the snap only to return in a hilarious scene in New Asgard. But while Korg isn't too good at Fortnite, he knows how to fight on the battlefield, seeing as he returned alongside his king in Avengers: Endgame's final battle. Sorcerers - In addition to Doctor Strange and Wong, sorcerers from all corners of the planet fought in Avengers: Endgame's final battle, and they were integral to keeping people safe when the Sanctuary-II rained fire on the battlefield. Wakandans - Just as in Avengers: Infinity War, the Wakandan army faced the brunt of Thanos' army, except this time they did it with dozens of other heroes from all across the galaxy - and they did so off their home turf. Howard the Duck - Howard the Duck was a surprise cameo in the first Guardians of the Galaxy movie, and he returned in the final Avengers: Endgame battle against Thanos. Kraglin - As one of the few remaining Ravagers, Kraglin joined the fight alongside the Guardians of the Galaxy to defeat the Mad Titan and his galaxy-destroying army once and for all. Ravagers

The justification of time travel is fundamental to Endgame's second act, with characters repeatedly questioning its possiblity. Of course, Tony Stark's scientific explanation - its perils are rooted in quantum chromodynamics theory, Scott turned into a baby and old man because of the EPR paradox and Deutsch proposition, the wrist devices derive from the eigenvalue of a particle field accounting for spectral decomposition under his Mobius strip configuration - glances with genuine theory but one without any real application. Yes, Mobius strip time travel is a pre-existing idea (it's at the heart of the grandfather paradox), but it's not how the film presents time travel. There are two scenes in Endgame where time travel is explained. First is Banner ahead of Hawkeye's test mission. Responding to Rhodey's suggestion of killing Thanos in the crib (an adaptation of the "kill Hitler" time travel theory), Bruce dismisses most time travel examples from popular culture (Back to the Future especially, but Star Trek, Terminator, Time Cop, Time After Time, Quantum Leap, Somewhere In Time, Hot Tub Time Machine and Bill and Ted's Excellent Adventure are all mentioned), stating "if you travel to the past, that past becomes your future and your former present becomes the past, which can't now be changed by your new future." The basic implication is that you can't change the past because you've existed in the future; no matter what you do, the end result is the same. Even if you were to try and kill baby Thanos, the future you have must be unchanged. Later, when Bruce is attempting to get the Time Stone from the Ancient One, she talks to him and elaborates on his idea further: "The Infinity Stones create what you experience as the flow of time. Remove one of the stones and that flow splits." This suggests that, while the post-Decimation future the Avengers have come from will be there when they return, their actions in the past can impact the timeline to the point that new timelines are created (which, due to the lack of Stones, are much more fraught). While it's possible any change could do this, it's only explicitly stated that it occurs when an Infinity Stone is removed from the timeline, which Bruce proposes can be fixed if they "return each one to its own timeline at the moment it was taken so chronologically, in that reality, it never left." In short, the Avengers can't change their own timeline as it already happened, so going into the past doesn't affect their own reality. However, removing the Infinity Stones from an earlier point does, creating darker timelines. To correct this, the Infinity Stones need to be returned to their original place in the timeline after use. Now, both of these exposition characters are shown in Avengers: Endgame to not have full knowledge of the situation - Bruce is enlightened by the Ancient One, who is herself later corrected by Doctor Strange's plan involving giving up the Time Stone - but given these are the film's prime exposition beats regarding time travel, they can be assumed to be intended as accurate by the filmmakers. The ambiguity comes with what is a big enough change to alter the timeline: taking an Infinity Stone creates a branch, but returning it would essentially uncreate it.

The Avengers intend to go back in time to takes the Infinity Stones to attach to their own, new Infinity Gauntlet. They split into four teams: Iron Man, Captain America, Ant-Man and Hulk to New York during The Avengers to get the Tesseract, Loki's Scepter and Mind Stone; Thor and Rocket to Asgard during Thor: The Dark World to remove the Aether from Jane Foster; War Machine and Nebula to get the Power Stone from the Morag at the start of Guardians of the Galaxy; and Hawkeye and Widow to retrieve the Soul Stone from Vormir. There's a question of why they needed to go to the events of the movies - while the Battle of New York makes sense due to the three Infinity Stone argument, the Aether was in the Collector's museum since Thor: The Dark World and the Power Stone on Xandar following Guardians of the Galaxy, situations with fewer timeline implications. Of course, that would make for a much less interesting film and is argued away in-universe as requiring characters' knowledge of events. The plan goes awry in multiple cases. Clint gets the Soul Stone but has to lose Natasha (which doesn't break the timeline). Thor talks to Frigga moments before her death, getting the goodbye he was robbed and a speech about being a hero, before taking Mjolnir. War Machine gets the orb, but Nebula is stopped from traveling back to the present by 2014 Thanos. Captain America gets the scepter after a tussle with his past self and Hulk the Time Stone (as well as knowledge of the timeline issues above) but Tony and Scott fail to secure the Tesseract, which Loki uses to teleport out; they instead go to 1970 to get it from Camp Lehigh in New Jersey, as well as more Pym Particles for the return journey.

The first true break (or diversion) of the Marvel timeline in Endgame is regarding the Space Stone in 2012. Tony and Scott intend to give 2012 Tony an arc reactor failure when he meets Secretary Pierce (something that presumably always happened), allowing them to remove the Tesseract briefcase from the equation. An angry 2012 Hulk complicates matters and the Space Stone is attained by Loki, who teleports out of New York. Following the rules laid down by the Ancient One (and the fact that the film puts focus on the Loki moment), this a clear and intended break in the Marvel timeline that is not resolved by the time Avengers: Endgame comes to an end. In this reality, Loki escapes capture at the Battle of New York with the Tesseract. The knock-on effects of this are serious: directly, Loki is still working for Thanos at this point so may give him the Space Stone years earlier; from a movie perspective, he isn't there for the events of Thor: The Dark World or Ragnarok, meaning Odin is never replaced and, possibly, Asgard may not be destroyed and Thor never loses Mjolnir; the Avengers also haven't completed their first mission, likely keeping them together longer and impacting solo movies up to and beyond Captain America: Civil War. The extent of all of this is speculation, sure, but the very immediate potential is massive. This would also mean that everything that happens subsequently in this time period is not part of the prime MCU universe: Steve Rogers didn't always fight his future self because he was never looking for Loki. Practically, this is a get around of Loki's death at the start of Avengers: Infinity War. Thanos declared "no resurrections this time" and he was right, from a certain point of view. Loki is dead in the MCU going forward, yet a version of him is alive and well for new adventures at his most malicious in another timeline, which is a topic that will surely be explored in the Tom Hiddleston-starring Disney+ Loki show.

A subset of the Thanos concern is Nebula. The notion of both versions being connected is actually rather logical by itself; think of it like taking a phone to the past - which one receives calls and messages? But when things are taken through to completion, it gets confusing. During the present-day battle in Avengers: Endgame's finale, future Nebula convinces past Gamora to join her (a reversal of their arc in Guardians of the Galaxy Vol. 2), which leads to a showdown in which future Nebula kills her past counterpart. Common time travel logic would make this a grandfather paradox - Nebula can't exist to kill herself - but there's no slow fade away. This is further evidence that whatever is happening after Thanos comes to the future is from its own existent timeline, although any further exploration - or even an acknowledgment of what's happened from Gamora or Hawkeye - isn't forthcoming.

The end of Endgame has one final big time travel reveal. When Steve Rogers goes back in time to replace all the stones and, as the movie tells it, correcting every potential issue, instead of returning to the present, he uses the Pym particles to jump to the 1940s to be with Peggy. He gets that date, that dance, that life that he was forever robbed from by his duty. This is confirmed by an appearance of a much older Steve just after he leaves, saying he was happy with the life his chose and passing the shield to Falcon. Thematically perfect and tear-inducingly delivered, this moment nevertheless creates even more complications thanks to, once again, borrowing from multiple forms of time travel. Captain America has inserted himself into the past, becoming Peggy Carter's husband. It's notable that Marvel movies have been avoiding giving much of Peggy's post-Agent Carter background even as they teased Steve's eventual fate. The only proper mention of her husband came in Captain America: The Winter Soldier where, in an archived video at the Captain America Smithsonian exhibit, she explained how he was someone Steve saved during World War II; Agent Carter was canceled before the show could reveal his identity as promised and pictures on her bedside further showed only her children. It's distinctly possible that this ambiguity was intended to hide that it was really Steve Rogers all along. This line of thinking comes with its own problems, many explainable. Steve and Peggy would have had to hide his return from the outside world, likely seeing him live under an alias. As spies, this would be well within their remit, and if the focus was on living a life together, a worthy sacrifice. It would also explain the now-incongruous fact that Peggy has a photo of young Steve on her desk; she's covering for him. It also doesn't make the Sharon Carter love story (too) disgusting as Steve wouldn't be her blood relative. Of course, that would directly work against what happened to Guardians of the Galaxy-era Thanos; following that logic, Steve's return would have started a new chain of events that would surely butterfly into a totally different, possibly Avengers-less future. This solution here would that old Steve turning up straight after his disappearance isn't just him simply revealing himself but having traveled across from another reality using Pym particles for a proper goodbye.

Reportedly, Endgame cost anywhere between $350-400 million to produce. Unadjusted for inflation, that undoubtedly makes it one of the most expensive films ever made - if not the most. The current official record-holder is Pirates of the Caribbean: On Stranger Tides, which cost $379 million. Infinity War came in at $316 million and Age of Ultron cost $365 million. No other MCU installment had a budget of more than $230 million (Captain America: Civil War).

Co-Director Joe Russo said removing Spider-Man from the Marvel Cinematic Universe was a "tragic mistake". Russo's comments follow Disney and Sony's failure to come to an agreement on financing for the franchise, leading to Tom Holland's superhero being cut from the MCU. "It was a tenuous, fraught union throughout the whole process," he told the Toronto Sun, describing the deal between Disney and Sony. "But, I will say, stepping back and trying to be objective as possible, that I think it's a tragic mistake on Sony's part to think that they can replicate [Marvel Studios boss] Kevin [Feige]'s penchant for telling incredible stories and the amazing success he has had over the years. "I think it's a big mistake."

Stark and his daughter, Morgan, express their love for each other using this phrase. In the pages of her own comic book, the spontaneous Gwenpool uses it to tell her (former) boyfriend Quentin Quire a.k.a. Kid Omega how she feels. Quentin is an omega level mutant, who goes by the code name Kid Omega. And while his powers include advanced cognitive and telepathic abilities, his response to the Endgame farewell confirms he's also and absolute monster. Gwenpool can do so much better. Exactly like her counterpart, Deadpool, Gwenpool knows full well that she is in a comic book series. She often addresses the fact in her comics, and in Gwenpool Strikes Back #2, she strives to get the perfect photo for the cover. Gwenpool wants a successful series, and wants Marvel to keep giving her work, and she is willing to do just about anything to make that happen. Including trying to seduce one of the members of the Fantastic Four (any of them, according to her). Deadpool is along for the ride on her mission, and thankfully points out to her that she has a boyfriend. Of course she feels guilty and immediately says that they broke up. When she pulls out her phone to text Quentin a break-up text, we see where she told him that she loves him 3000. However, he didn't understand the reference! So the fact that they are still together is pretty impressive because anyone who doesn't get the reference doesn't deserve to be with Gwenpool.

At the 45th Saturn Awards honored the best in fantasy, sci-fi, and horror motion pictures, television shows and more, Endgame, won six total awards, including Best Comic-to-Motion Picture Release and Best Actor in a Film for Robert Downey Jr.

Took 11 days to reach 2 billion dollars at the box office that's double the amount avengers infinity war made in 11 days

Co-writer Christopher Markus confirmed that the Red Hulk was briefly supposed to appear in the film. However, it's not exactly clear what role he would have had or how different it might've been from the Red Hulk's role in the comic book Marvel Universe. Markus implies that Endgame's Red Hulk would have simply been Bruce Banner by stating that "really we're just saying he changes color." Instead, the MCU's Hulk's changes into his "Professor Hulk" persona, which combines the Hulk's strength and body with Banner's intelligence and was introduced during Peter David's iconic tenure on Incredible Hulk. This still has shades of the Red Hulk, who has both intelligence and the ability to transform at will in comics. Considering how that transformation happened off-screen, it stands to reason that the Hulk's transition from green to red would've happened off-screen too, and it likely would've drawn the same criticism that unseen development did.

One fan theory about how the Avengers would defeat Thanos once and for all gained immense traction online prior to the film's release: Ant-Man, while tiny, would go inside Thanos' anus, and then grow giant. This became known as the 'Thanus' theory, which Paul Rudd reluctantly approved of and some scientists proved could technically work, even if Thanos was carrying all six Infinity Stones. One fan went as far as to predict an alternative: already giant-sized, Ant-Man would stick Thanos in *his* anus, and then shrink. Of course, neither of these events occur in the final film.

Emily VanCamp, who recently revealed her character's whereabouts during the last two Avengers movies. Sharon Carter/Agent 13 premiered in Captain America: The Winter Soldier, and reprised her role in Phase Three's opener Civil War. She was an ally and potential love interest for Steve Rogers, and was last scene sharing a kiss with the Avenger and giving #TeamCap their equipment ahead of the big tarmac battle. And now Emily VanCamp has explained where her character has been since, saying: "We're obviously going to find out where Sharon's been all this time because she's been on the run."

Tony, Banner & Rocket prepared gauntlet for 6 Infinity Stones collected out of Nanotech. Now Nanotech Guantlet was not designed to absorb the enormous power channeling off all the 6 stone together. If you recall, in Avengers - Infinity War Etiri prepared the Gauntlet of Strongest known metal of which Strombreaker & Mjolnir were made off and was specifically designed to absorb the enormous power channeling off stones. That is the reason why Thanos after using all 6 stone together didn't had considerable amount of damage as Hulk and Tony had. Etiri being dusted because of Thanos snap isn't clear as it isn't being said or discussed. Thor should have prompted them to go to Etiri for preparing Gauntlet which is very easily possible as Strombreaker can summon bifrost and reach there within no time. Maybe it can be inferred that Etiri was dusted, but again it should have been clarified by the writers as it's kind of a loophole in movie story.

Jim Starlin: the creator of Thanos appears as a member of the support group. He is the bald man with the glasses and a goatee.

Joe Russo: The co-director of Captain America: The Winter Soldier (2014), Captain America: Civil War (2016), Avengers: Infinity War (2018), and this film appears as Grieving Man in the support group scene. Two other directors of MCU films are also in the cast of this film, reprising named roles from MCU films they directed: Taika Waititi (director of Thor: Ragnarok (2017)) as Korg and Jon Favreau (director of Iron Man (2008) and Iron Man 2 (2010)) as Happy Hogan.

Joe Russo: as the support group member who talks about going on a date for the first time after losing his male partner, marking the first time an openly gay character has been featured in the MCU. He earlier made cameos in Captain America: The Winter Soldier (2014), Captain America: Civil War (2016), and in a deleted screen from Avengers: Infinity War (2018).

At Tony Stark's funeral, a teenage boy is seen standing behind Scarlet Witch and Bucky. This is Harley Keener (Ty Simpkins), the boy from Iron Man 3 (2013) who let Tony use his shed when he needed to repair his Iron Man suit.

Captain America wielding Thor's hammer, Mjölnir, comes from the comics, where Steve Rogers has proven himself worthy by the enchantment cast on the hammer. This also marks the second film where Steve Rogers makes an attempt to wield Mjölnir. The first was in Avengers: Age of Ultron (2015), though in that film he was only able to move the hammer slightly off the table. That subtle movement was noticed by Thor. Director Joss Whedon hinted in an interview that Rogers had been able to lift the hammer the whole time, but didn't, so as to not hurt his friend Thor's feelings.

In The Avengers (2012), Captain America tells Iron Man, "You're not the guy to make the sacrifice play," and Iron Man tells Captain America, "Everything special about you came out of a bottle." In this movie, each proves the other wrong. Iron Man sacrifices himself to defeat Thanos, while Captain America proves himself worthy by being able to wield Thor's hammer, Mjölnir.

The iconic comic book line "Avengers Assemble!" is finally said on screen by Captain America prior to the final battle. This was teased at the end of Avengers: Age of Ultron (2015), but the film cuts to the credits before the line is fully spoken.

In the final battle, Thanos breaks Captain America's shield in half, fulfilling the prophecy in Avengers: Age of Ultron (2015). Also shown in the vision is Hulk injured and unable to fight, similar to Avengers: Infinity War (2018), Black Widow dead in the same position as she dies in "Endgame", and Thor appearing to be dead in the same position as when Thanos wounds him with Stormbreaker in the final battle.

Edwin Jarvis, played by James D'Arcy, becomes the first character in the MCU to be introduced in a Marvel TV series and make an appearance in a movie. The character was first introduced in Agent Carter: Now Is Not the End (2015) and was a regular cast member on Agent Carter (2015). This also marks the first time the original Jarvis is seen in a film, as he had been replaced by the computer program J.A.R.V.I.S. (voiced by Paul Bettany) in previous films.

The song Steve Rogers and Peggy Carter dance to is the same song that Nick Fury is listening to in Steve Rogers's apartment after he is attacked in Captain America: The Winter Soldier (2014).

In the funeral scene, Morgan asks for a cheeseburger and Happy smirks and says that her father loved cheeseburgers. This is a reference to Tony Stark requesting "an American cheeseburger" upon arrival at the press conference, after escaping from the cave in Iron Man (2008).

In a lighthearted scene toward the end of the film, Thor joins Star-Lord and the rest of the Guardians of the Galaxy and calls the team the "Asgardians of the Galaxy". Thor: Ragnarok (2017) was frequently and humorously referred to as "Asgardians of the Galaxy", due to the film's tonal similarities with Guardians of the Galaxy (2014). A Marvel comic titled "Asgardians of the Galaxy" debuted in September 2018, featuring a team of Asgard-related characters including Angela, Valkyrie, Kevin Masterson, Throg, Skurge, and the Destroyer.

In Spider-Man: Homecoming (2017), Peter mistakes Tony's reaching for the car door as an attempt to hug him. When Peter returns the gesture with a hug, Tony responds, "That's not a hug; I'm just grabbing the door for you. We're not, we're not there yet." In "Endgame" (2019), when Peter and Tony are reunited, Tony immediately pulls him in for a hug.

Similar to what was done with Samuel L. Jackson and Clark Gregg in Captain Marvel (2019), digital de-aging was also applied in this film to make Stan Lee look younger for his cameo appearance, which would take place in 1970. Digital de-aging was also applied to Michael Douglas (Hank Pym) for his 1970 appearance, and has been used in several Marvel Studios films to create noticeably younger versions of characters for certain scenes (such as Robert Downey Jr.'s Tony Stark in Captain America: Civil War (2016), Douglas's Pym in Ant-Man (2015) and Ant-Man and the Wasp (2018), and Michelle Pfeiffer's Janet Van Dyne in Ant-Man and the Wasp (2018)).

Captain America ends this film by dancing with Peggy Carter, keeping the promise he makes right before he puts the Hydra plane into the ocean in Captain America: The First Avenger (2011).

Anthony Mackie was surprised to learn what his character's ending as Falcon was and, as if by fate, he learned this info from none other than Chris Evans himself. He stated in an interview: "We were at his house and Chris goes, 'You excited?' And I go, 'What are you talking about?' He goes, 'You don't know?!' And he jumps up, runs out of the room, and comes back in with the script. We cried. We drank. We laughed. I am very happy I got that moment with Chris, for him to not only pass me the shield, but to tell me it was happening."

When Captain America is going to the Quantum Realm to return the Infinity Stones, he asks Bucky not to do anything stupid. Bucky replies by saying, "How can I? You are taking all the stupid with you." This is the exact dialogue between the characters from Captain America: The First Avenger (2011). The only change is that, in that movie, Bucky is going to war and asks Steve not to do anything stupid. Steve gives the same reply.

Scott Lang as an old man is played by Lee Moore. This was his last film, and he died before it was released.

"New Asgard" is actually a village in the southern borders region of Scotland, called St Abbs. Thor can be seen drinking Innis and Gunn, a beer brewed in Scotland. Other hints to Scotland in this scene are the bottle of Irn Bru on the windowsill, and the golf club behind Thor's head. (In the comics, after its Ragnarok destruction, Asgard was rebuilt on Earth, outside of Broxton, Oklahoma.)

The somber ending to Avengers: Infinity War (2018) was going to be this film's beginning; had that been the case, "Infinity War" would have ended with Thanos completing the Infinity Gauntlet, before actually using it in this movie. However, the creative teams working on the two films decided that it best suited the story to have the actual cliffhanger follow the finger snap itself and to show its fallout before, making viewers wait a year to see how the story would be resolved.

During the funeral scene, Tom Holland, who plays Spider-Man and is notorious online for accidentally giving spoilers away in press junkets, was told they were filming a wedding.

When Natasha, Steve, and Scott go to visit Tony to convince him of the time travel plan, Natasha is seen wearing a necklace with an arrow on it. This is a nod to her friendship with Hawkeye, who is still rogue at this point in the film.

Clint Barton appears in Japan with the identity of Ronin in this film. This is based on the comics, where, in the aftermath of the "Civil War" event, he took up the Ronin identity during a mission to Japan with the New Avengers to save Echo (Maya Lopez), who had been the previous Ronin. Barton has a tattoo of a ronin on his arm, as a further homage.

Robert Redford reprises his Captain America: The Winter Soldier (2014) role of Alexander Pierce. Prior to this film, he announced he was retiring from acting; therefore this film is intended to be his final film appearance.

The 2012 version of Thor using Mjölnir as a magical defibrillator is straight out of the comics, where he has done this several times in the past, sometimes even summoning entire bolts of lightning for more sturdy patients.

With this film, along with Captain America: Civil War (2016), Spider-Man: Homecoming (2017), and Avengers: Infinity War (2018), Tom Holland breaks Tobey Maguire's record for playing Spider-Man in live-action movies the most times.

The mid-credits scene from Captain Marvel (2019), believed to be taken from this film, does not appear in the final cut.

Set photos leaked showing Robert Downey Jr., Chris Evans, Chris Hemsworth and Tom Hiddleston wearing outfits and costumes from the first Avengers film, as well as the rubble-filled New York set where the final battle of The Avengers (2012) is set. This led many to believe that either a flashback sequence or time travel would play a major role in this film. The fact that Ant-Man was seen among these characters created speculation that he would be the one to travel back in time by means of the Quantum Realm; this theory seemed all the more likely after the mid-credits scene of Ant-Man and the Wasp (2018), where he becomes trapped in the Quantum Realm after receiving the warning to avoid the time vortex. This hypothesis was indeed confirmed to be the case as the Avengers build their own quantum tunnel designed for time travel so that they can retrieve the Infinity stones from the past after Thanos destroyed them in the present.

Joe Russo has confirmed in interviews that elderly Steve found a way to make another time jump from his alternate reality with Peggy towards his original with Sam, which is left to be a mystery for now.

In The Avengers (2012), Tony tells Bruce Banner that the exposure to gamma radiation should have killed him if it wasn't for the other guy (Hulk). When Bruce asked Tony for what purpose the Hulk would have saved him, Tony said they will find out. "Endgame" gives the answer to the question, as Bruce (now fused with the Hulk) is the only one capable of using the Gauntlet to bring everyone back. He even says he was always meant for this purpose before snapping his fingers.

Aaron Taylor-Johnson's character, Quicksilver/Pietro Maximoff, was seen in set pics of this film, hinting that he might return or just briefly make an appearance in a flashback scene of Avengers: Age of Ultron (2015). In the final cut of the movie, he is missing.

At the end of the climactic battle with Thanos, Rhodes is the first one to find Tony dying from his injuries. This pays tribute to Rhodes being the first one to find Tony in the desert in the beginning of him being Iron Man. Rhodes is also the first one to find him at the end of him being Iron Man. Also, it reverses Tony being the first to find the severely injured Rhodey after the airport battle in Civil War.

Thor (Chris Hemsworth) was supposed to confront his 2012 self, but the idea was ultimately scrapped, as revealed by directors Joe Russo and Anthony Russo. While it was Captain America (Chris Evans) who had a direct entanglement with himself from the events of The Avengers (2012)'s Battle of New York from 2012, and Nebula (Karen Gillan) with her evil counterpart from 2014's Guardians of the Galaxy (2014), apparently Thor was supposed to have his own similar moment in "Endgame". Speaking with MTV's podcast, the Russos said that the initial plan was to have a Thor vs. Thor confrontation in Asgard. However, they felt like "it overly complicated [the plot]", adding that they also liked the "Cap vs. Cap better", so they gave up the bit. Instead, they gave Thor a different experience when he went back in time - another chance to talk to his mom and properly say goodbye to her, commenting, "I think there, we also deferred to the storyline between Thor and his mother. [It] was so resonant, that we really wanted to run... That was really more a part of Thor's journey and repair than confronting his former self. So that's really what happened there, why we went with that."

In the 3D version of the film, the funeral scene is presented in 2D, unlike all the rest of the scenes.

Co-director Joe Russo was asked about the injury sustained by the Hulk when using the makeshift Iron Gauntlet to snap everyone back to life, his arm in a sling during Tony Stark's funeral, and it appears this isn't something he'll be able to heal from. Joe Russo explained: "He's lost an arm. He lost Natasha. That's not coming back. He's damaged himself. I don't know. It's interesting. That's permanent damage, the same way that it was permanent damage with Thanos. It's irreversible damage. His arm, if you noticed, is a lot skinnier. It's blackened. So, he loses a lot of strength there."

When Tony and Cap infiltrate the S.H.I.E.L.D. base, Cap wears an Army uniform with - quite appropriately - captain's bars on his hat.

During the final battle, there is a scene showcasing only the female MCU heroes. This is a reference to the A-Force, a team of all-female Avengers which appeared in Marvel Comics from 2015 to 2016. Some of the characters from the A-Force comics are featured in the scene, including Captain Marvel, Rescue (Pepper Potts), and Scarlet Witch.

The cast includes 19 Academy Award nominees (for acting and non-acting categories): Angela Bassett, Josh Brolin, Don Cheadle, Bradley Cooper, Benedict Cumberbatch, Michael Douglas, Robert Downey Jr., William Hurt, Samuel L. Jackson, Brie Larson, Gwyneth Paltrow, Michelle Pfeiffer, Natalie Portman, Robert Redford, Jeremy Renner, Mark Ruffalo, Tilda Swinton, Marisa Tomei, and Taika Waititi. Of those nominated, Douglas, Hurt, Larson, Paltrow, Portman, Redford, Swinton and Tomei have all won at least one Academy Award. Douglas has two Academy Awards, one for Best Picture for One Flew Over the Cuckoo's Nest (1975) and one for Best Actor for Wall Street (1987).

New Asgard, originally the Norwegian city Tønsberg, was also the site of the battle between Asgard and the frost giants of Jotunheim shown in Thor (2011), along with the location that Red Skull stole the Tesseract from in Captain America: The First Avenger (2011).

After Tony snaps his fingers at the end, a scene was filmed with him having a vision of his daughter Morgan, now grown up, played by 13 Reasons Why (2017) star Katherine Langford. Much like Thanos's conversation with a young Gamora in Avengers: Infinity War (2018), Tony and Morgan would discuss what he'd just done and she'd forgive him, putting him at peace. The scene was ultimately scrapped because there wasn't the emotional connection with an adult version of his daughter, and the Russos dismissed it as "too many ideas in an overly complicated movie."

The end of the movie pays homage to the graphic novel "House of M", where the reader gets to see how heroes would have lived out their own opinion of their ideal life. It shows that Steve Rogers wishes he had never been frozen or famous, just returned to Brooklyn after the war to grow old in anonymity. This is exactly what Steve does when he goes back in time and rekindles his life with Peggy.

After the whole intense climax and Tony's funeral, Steve Rogers a.k.a. Captain America is shown going through the miniaturized time heist machine to deliver all six Infinity Stones and Mjölnir to their respective locations in the past from where the Avengers borrowed them earlier in the movie. It's interesting to note that the Soul Stone which Clint brought from Vormir, after Natasha sacrificed herself for it, is guarded by Johann Schmidt a.k.a. Red Skull, who is the main nemesis of Captain America from Captain America: The First Avenger (2011). Captain returning in the end, delivering all the Stones to their respective places, indicates that he interacted with Red Skull, which isn't mentioned or shown in the movie.

When Red Skull meets Clint, he calls him "son of Edith", despite having called Thanos, Gamora, and Natasha the child of their respective father. In the comics, Harold Barton was abusive and an alcoholic. Clint and Nat's "fight" for the Soul Stone (requiring the death of someone you love) recalls their turbulent relationship in the comics. Nat sacrificing herself for Clint to obtain the Soul Stone (which eventually revives his family) is the direct opposite of the Ultimates where Black Widow is the one who killed Clint's family.

Towards the end of the movie, at the time of Tony Stark's funeral, Morgan Stark (Tony's and Pepper's daughter) is shown a recorded message from Tony which he had recorded in case of his untimely death in the form of 3D hologram of himself. This is a nod to further development of the BARF (Binarily Augmented Retro-Framing ) technology invented by Tony Stark, introduced in Captain America: Civil War (2016) for therapeutic pursuits. BARF would also make an appearance in Spider-Man: Far from Home, revealed to be Quentin Beck's technology and the reason for Beck's hatred of Tony.

The arc reactor that says "Proof that Tony Stark has a heart" is the gift Pepper made for Tony in Iron Man (2008) after she removed his old reactor.

Hawkeye is seen wearing an ankle monitor in the opening scene. This is the same device that Scott Lang wears in Ant-Man and the Wasp (2018), which means that both he and Hawkeye were under house arrest following the events of Captain America: Civil War (2016).

The characters that relay the Gauntlet from Clint to Tony are Black Panther, Spider-Man, and Captain Marvel, all of whom will be part of the upcoming Phase 4 of the Marvel Cinematic Universe. Thus the passing of the Gauntlet is a metaphor for the first generation of MCU characters passing the franchise to the next generation.

Between this movie and Avengers: Infinity War (2018), there have been four snaps with the completed Infinity Gauntlet: the first one done by Thanos to wipe out half the universe, the second also done by Thanos to erase the stones from existence, the third by Hulk to undo the first snap, and the fourth by Tony Stark to eliminate Thanos and his army.

Morgan Stark, the daughter of Tony Stark and Pepper Potts, was based off the character Howard Stark III, who was their son from an alternate reality in the comics (from Invincible Iron Man #500 that was published in 2011). This is also the fourth film to have a character portrayed as the opposite gender from their comic book counterpart, which was preceded by the Ancient One from Doctor Strange (2016), Ghost from Ant-Man and the Wasp (2018), and Mar-Vell from Captain Marvel (2019).

In Captain America: Civil War (2016), when Hawkeye and Black Panther first meet and fight, Clint pauses and says, "We haven't met yet. I'm Clint," to which T'Challa replies, "I don't care." That is the first and only time they meet before T'Challa disappears at the end of Avengers: Infinity War (2018). The next time they meet is in this movie, during the final battle scene. When Ronin/Clint surfaces with the new Gauntlet, T'Challa comes to his aid and finally calls him by his name, indicating the evolution of their relationship from adversaries to allies.

The funeral scene was referred to as "the most complicated scheduling shot in the history of cinema." It's legit with everyone in attendance and no one stitched in digitally.

Steve finally lifting Mjölnir with the war cry "Avengers Assemble!" is right out of the "Fear Itself" story arc, where he rallies Avengers and civilians in the battle against the Serpent. In the movie, he rallies the resurrected heroes in the final battle against Thanos.

During the final battle, the Wasp fixes Ant-Man with a challenging stare after she responds to Captain America's orders. This is a callback to Ant-Man and the Wasp (2018), where Hope admits she was angry with Scott for not asking her to help during the events of Captain America: Civil War (2016). Also, she calls him Cap instead of the full "Captain America". In Ant-Man and the Wasp (2018), she had made fun of Scott for doing the same. Back then, he had replied that it's what Cap's friends call him.

When Tony hands Steve back his shield, you can hear the opening stanza of Alan Silvestri's "Captain America March" play in the background.

The writers said they got inspiration for the Avengers' unexpected character development in the "Five Years Later" sequence from Marvel's "What If?" comics.

Korg, a character voiced by Thor: Ragnarok (2017) director Taika Waititi, is seen wearing a pineapple shirt matching the pineapple romper that Taika wore for much of the promo images and interviews for "Thor: Ragnarok".

When mentioning movies with time travel in them, they mention the comedy movie Hot Tub Time Machine (2010). Sebastian Stan (Bucky Barnes) plays a bully in that movie.

While he does not say it, Captain America being the last man standing and being ready to fight Thanos and his army, even though the odds are against him, calls back to the moment in the "Infinity Gauntlet" comic where Cap tells Thanos that as long one man is left standing, he has not won yet. Additionally, Thanos destroys Cap's shield during their battle, which is something that also happens in the original comic.

They went through variations of how Thor's stone mission would unfold including having him focus on Jane seeing as she has the stone, but "we realized that the work emotionally that needed to be done on Thor wasn't romantic work, it wasn't scientific work, it was a kind of absolution that only his mother could give."

Natalie Portman's brief cameo as Jane Foster was unused footage from Thor: The Dark World (2013). Portman however did reprise her role in some small capacity: she recorded a new voiceover for when her character is seen in the distance talking to Frigga.

Vin Diesel says "I am Groot" only once in this film, in the scene when Thor and Star-Lord fight over who should lead the Guardians. The rest of the Guardians suggested a knife fight. Groot's one line translated to "I like knives".

The fate of Iron Man and Captain America was decided very early in the creative process of Marvel Studios' Avengers: Infinity War.

Even though this is the fourth Avengers film, this is the first film that contains all members of the original lineup that appeared in Avengers #1 (1963). Iron Man, Thor, Hulk, Giant-Man/Ant-Man, and the Wasp were the founding members. Hank Pym and Janet Van Dyne were Ant-Man & Wasp in the comic at the time, not Scott Lang and Hope Van Dyne. Hank and Janet do appear, though, in this film. Loki was the main antagonist in the first issue, and also makes an appearance in the film. Captain America didn't join the team until Issue 4; however, he was later given founding member status.

In the final battle, Howard the Duck appears briefly amongst the Ravagers from Guardians of the Galaxy Vol. 2 (2017). Despite only being visible for 18 frames (less than 1 second), the 3D model was fully rigged and included detailed animations for the feathers.

In his recorded will to Pepper, Tony cheekily compares Nebula to a "Blue Meanie" from The Beatles' animated movie, Yellow Submarine (1968). In the French version, he calls her the "Smurfette", instead. He also snarkily calls Thor (after five years of letting himself go and drinking like crazy) "Lebowski" and refers to Rocket as "Ratchet".

In the original Iron Man (2008), the soundtrack used a short excerpt from the classic rock song "Iron Man" by Black Sabbath. In this movie, Iron Man fulfills the line of the song, "where he traveled time, for the future of mankind".

Some online have clearly been unhappy with Thor's (Chris Hemsworth) descent into depression and weight gain, but the filmmakers love it. They praise his performance as it's difficult to portray pathos and humor simultaneously, but they also think it's a fantastic balance of comedy and sadness that work to build emotion. "What's great about this character is we commit to it, and he doesn't change by the end of the film."

The prosthetic belly worn by Chris Hemsworth to portray Thor after 5 years of drinking beer and playing video games was made of silicone and latex, and weighed around 88 lbs. (40 kg). It was carefully detailed to match the hairs and moles on Hemsworth's actual body. He reports that all the cast members kept rubbing the false belly, and he felt a bit like Santa Claus.

Originally, Tony does not say anything before he snaps his fingers at Thanos. The line 'I am Iron Man' was added during additional filming three months before release. Interestingly, it was the last piece of footage shot for the film. According to the Russo brothers, it was editor Jeffrey Ford who suggested putting that line saying that Tony should at least say something in response as the original version didn't service the moment correctly. Anthony Russo said that [ljnk=nm0000375] was quite hesitant in re-shooting that key shot as it was hard for him to get into the emotional state required until Downey Jr.'s friend, Kiss Kiss Bang Bang producer Joel Silver, bumped into them over a dinner meeting and persuaded him to say that famous line.

The two beers Thor is drinking after getting picked up are called Athena (yellow and white can) and Tropicalia (orange and blue can), which are brewed by Creature Comforts in Athens, GA. When this was filmed, the brewery would have only been distributing in Athens and Atlanta, with Atlanta being one of the primary filming locations. The Russo Brothers are big fans of Creature Comforts and have been seen wearing the brewery's shirts at events and panels, such as D23 Expo.

Steve's military uniform in the 1970 New Jersey scene is labeled "Roscoe". It refers to the Marvel Comics character Roscoe Simons, who was another Captain America.

Hawkeye has become the darker and edgier vigilante Ronin after losing his family when Thanos wiped out half of the universe's population. This mirrors the events of The Ultimates 3, where Hawkeye donned a new costume and adopted a more violent, suicidal attitude after his family was murdered in The Ultimates 2. It also refers to the 616 version taking on the Ronin identity post "Civil War". As the vigilante Ronin, Clint's take-no-prisoners attitude against criminals after the death of his family makes him similar to the Punisher, another character who frequently partners with Black Widow.

Steve fighting with his 2012 self is a direct reference to Captain America #156.

Black Widow sports a new hairstyle after five years: red roots with blonde tips. After the events of the Captain America: Civil War (2016), she dyed her natural red hair blonde to avoid being recognized. Red roots with blonde tips tell us she deemed it unnecessary to keep dying her hair blonde after the events of Avengers: Infinity War (2018), but also didn't dye her blonde hair back to red because she was too busy trying to do her best as the de facto director of the Avengers.

Before Tony's funeral, the cast was told it was a wedding scene and did not find out about the truth until they were preparing for the scene.

During the movie, Back to the Future (1985) is mentioned a few times. Alan Silvestri, the composer, scored both this movie and "Back to the Future", among many others.

At the final fight scene, when Captain America appears to face Thanos' army by himself, he hears Sam's (Falcon's) voice, Sam utters the same phrase that Captain America used in Captain America The Winter Soldier, during their run in the opening scene, "On your left".

The concept of Captain America permanently going back to his time in the 1940s to be with Peggy Carter after the final battle, and his later appearance as an old man in the present, is similar to Bucky Barnes's Ultimate Marvel counterpart. In that version, Bucky survived WWII and married Cap's ex-girlfriend Gail Richards, and later appeared in the present as an old man after Cap was thawed out, as seen in the third issue of the Ultimates (the Ultimate Marvel version of the Avengers) and its later animated film adaption, Ultimate Avengers (2006).

At the end of the meeting between Tony Stark (Robert Downey Jr.) and his father Howard Stark (John Slattery) in 1970, Tony says, "No amount of money ever bought a second of time." This is a partial reference and a hidden nod to Edison, the Man (1940), where Thomas Alva Edison (Spencer Tracy) says, "All the money in the world, you cannot buy a minute of it." Both Stark and Edison are well-known as genius scientists.

Although Vision has his own poster for this film along with other characters who were killed off during "Infinity War", he's the only one not to return in any capacity, making this the only Avengers film not to include Paul Bettany.

The finale has Thor dual-wielding Mjölnir and Stormbreaker, similar to the climax of Jason Aaron's "The God Butcher/Godbomb" story where Thor dual-wields the hammers of his present and future selves at the same time. It also recalls the scene from Jonathan Hickman's Avengers where the Unworthy Thor uses both his axe and an alternate Mjölnir that previously belonged to a Mirror Universe version of Thor during the battle against the Beyonders.

Pepper's Rescue armor is purple, which is what it was colored in the Iron Man: Armored Adventures (2008) cartoon rather than the comics. The female heroes joining together to help Captain Marvel get to the quantum tunnel serves as a nod to the comics' A-Force, first introduced in "Secret Wars" (2015).

When Thor decapitates Thanos, Rocket asks him what he did. Thor sadly tells him, "I went for the head," to echo Thanos's taunt from the previous movie. It shows how Thor is still reeling from his previous mistake.

In the beginning of the film, Tony Stark and Nebula have been lost in space for 22 days, a nod to "Avengers: Endgame" being the 22nd film of the Marvel Cinematic Universe.

When Thanos attacks the Avengers HQ and the entire building collapses, the Hulk holds up the rubble, saving War Machine and Rocket Raccoon until Ant-Man comes to the rescue. This is a reference to the comic book miniseries "Secret Wars", in which the Beyonder takes a number of villains and heroes from Earth and puts them on a planet to fight each other. During one of the early battles, Molecule Man drops a 150-billion-ton mountain on the heroes and the Hulk is able to hold up the entire mountain by himself until they figure out how to get out.

During the "Five Years Later" sequence, there is a shot of Citi Field, the stadium of the New York Mets baseball team. Later, the grieving man in Captain America's support group says he misses the Mets. The movie references the Mets because the team did promotional tie-ins with Marvel based on pitcher Noah Syndergaard, who was nicknamed "Thor" for his resemblance to the character. The Mets had done giveaway days of such items as Syndergaard Thor bobblehead dolls and T-shirts.

Despite rampant rumors that it may happen, due to Fox being acquired by Disney, no non-MCU characters appear in the film (X-Men, Deadpool, Fantastic Four, etc.). There is also no indication as to how these characters may be incorporated in the future.

In the film's epilogue, Ned is shown wearing a t-shirt featuring the titular character from The Iron Giant (1999). That film was very loosely based on Ted Hughes' 1968 novel coincidentally entitled "The Iron Man". The film features a giant metallic man who ultimately sacrifices himself to save the world, vaguely referencing Iron Man's ultimate fate here. Vin Diesel (Groot) provided the voice of the Iron Giant.

The scene where Lang reunites with his daughter leaves all of the film crew misty eyed no matter how many times they watch it, and they credit Rudd's performance and improvised line "You're so big."

The only time a live-action adaptation of Spider-Man has used an Instant Kill option. It is seen briefly in Spider-Man: Homecoming (2017) when Peter tries out his new suit but instantly undoes the function.

The Ancient One can see the future but only up to the point of her death, and that's why she's unaware of Dr. Strange's choice to willingly give Thanos the stone in Infinity War. She can't understand why but knows there must be cause, so it's what finally convinces her to go against her own instincts and knowledge.

As a nod to the events from the ending of Avengers: Infinity War (2018), only the heroes who weren't caught in the Decimation effect were shown in the Marvel Studios sequence for this film, while the ones who died were removed.

When the Avengers are arguing the Time Heist plan, the movie Back to the Future (1985) is referenced repeatedly. When Hawkeye does his first trip through time, he arrives in a barn, just like Marty McFly did in "Back to the Future".

In a deleted scene, after Tony Stark snapped Thanos and his army out of existence, Tony went into the Soul World, like Thanos in the previous movie Avengers: Infinity War (2018). This time Tony had a conversation with his daughter, a teenage Morgan H. Stark (Katherine Langford), just like Thanos had a conversation with his adoptive daughter Gamora's child version in the previous movie.

At one point, Tony Stark calls a more "casual" version of Thor "Lebowski". In the first Iron Man (2008) movie, the character of Obadiah Stane, who is Tony Stark/Iron Man's mentor/friend/nemesis, was played by Jeff Bridges, who is very well-known for playing Jeff "The Dude" Lebowski, the main character of the movie The Big Lebowski (1998). As with the Dude, Thor is wearing pajama bottoms, a T-shirt, a bathrobe, and Ray Ban shades. Additionally, Chris Hemsworth (who plays Thor) co-starred with Jeff Bridges in the 2018 film "Bad Times at the El Royale".

Akihiko, the Japanese gangster killed by Clint Barton (Jeremy Renner), is played by Hiroyuki Sanada, who also played Shingen Yashida in The Wolverine (2013). He had previously played a leading role next to Chris Evans in Sunshine (2007).

In the final battle when all the MCU heroes show up, Ant-Man emerges as Giant-Man and carries the Hulk in his palm. This was a reference to the Super Bowl Coke commercial from 2016, when the two were reversed in size. In the ad, Ant-Man stole a mini Coke can from the Hulk, then had to help him open it.

Despite speculation and rumors, the Netflix Marvel characters like Daredevil, Jessica Jones, Luke Cage, Iron Fist, Elektra, and The Punisher do not make an appearance in this film.

The first draft of the script didn't include Rogers crossing paths with Peggy Carter in 1970.

In a post-credits scene of The Avengers (2012), following the Battle of New York, The Other talks to Thanos saying humans are unruly and not the cowering wretches they expected; in this film when Thanos of 2014 views Nebula's memory drive he immediately recognizes the Avengers and refers to them as unruly wretches.

Nebula's significant screentime in this movie is true to the comics on how she was instrumental in Thanos's downfall in "Infinity Gauntlet". 2014-Nebula being Thanos's lackey who sets up the final battle is the closest the MCU has to Terraxia, Thanos's Distaff Counterpart created via the Infinity Gauntlet.

Steve tells his support group that they need to move on after the Snap, and make something of what they have left. Otherwise, Thanos might as well have killed all of them. When the Avengers demonstrate their complete inability to do just that, Thanos comes to this exact conclusion, changing his plans from "50%" to "100%".

In earlier script drafts, the roles of Natasha and Clint are reversed during their final tag along in Vormir. It received mixed reaction from the crew until VFX producer Jan Underdahl became very emotional and unhappy after reading it. It was eventually decided by the Russo brothers that Natasha should sacrifice herself as it would be too melodramatic if it was Clint instead, as he is a family man in contrast with someone who is a cipher and comes from an abusive, terrible background. Screenwriters Christopher Marksus and Stephen McFeely said that would bring her character's story to a natural conclusion. The filmmakers have confirmed that Natasha's death is *permanent* reasoning that the explicit requirement of trading a soul for the Soul Stone is an irreversible process (not even by returning it) and the tribute soul will forever be sealed in Vormir.

Concept artist Ryan Meinerding shared a considered twist on the climactic scene where Captain America wields the legendary hammer Mjolnir, which can only be used by someone who is deemed worthy. "I thought it would be great if we could see Cap uncertain if he could lift Mjolnir or not," he captioned the image, which shows the hero reaching for the weapon amongst the rubble. Brie Larson recently posted a photo of herself holding the hammer, which caused Natalie Portman to ask her to go easy on it, since she needs it for Thor: Love and Thunder.

During the first meeting between the Avengers and Captain Marvel in the Avengers' headquarters, holograms are shown of those decimated by Thanos: Erik Selvig, Shuri, T'Challa, Sam Wilson, Stephen Strange, Peter Quill, Groot, Drax, Mantis, Hank Pym, Janet Van Dyne, Hope Van Dyne, Bucky Barnes, Peter Parker, Wanda Maximoff, Maria Hill, Sharon Carter, and Nick Fury.

Ant-Man being seen interacting with the Avengers during the Battle of New York is a nod to the fact that Ant-Man was one of the original members of the Avengers in the comics, along with the Wasp (although in the comics it's Hank Pym instead of Scott Lang).

In the 1970 sequence, a S.H.I.E.L.D. agent describes Tony Stark as having a "Mungo Jerry" beard. Mungo Jerry were a British skiffle revival band who had a massive international hit in 1970 with "In The Summertime," and whose members indeed sported well-sculpted facial hair. Ironically, lead singer Ray Dorset had what can only be described as the opposite of Tony Stark - the extremely long sideburns not unlike those later made famous by Wolverine from the X-Men.

Just after the time skip to five years later, we see Steve Rogers leading a support group for people who have lost loved ones following Thanos's attack, attempting to help people move on. This seems to mirror Sam Wilson's appearance in Captain America: The Winter Soldier (2014), in which he leads a support group for veterans at the local VA. This seems to foreshadow the idea that both Sam and Steve have similar roles for people in times of crisis, which helps explain why Steve passes his mantle on to Sam at the end of the film.

During Tony Stark's funeral, a flower wreath is sent across the lake with Tony Stark's original arc reactor chest piece. Previously, during the events of Iron Man (2008), it was placed in a glass case by Pepper Potts and the words "Proof that Tony Stark has a heart" were engraved on it, which is also seen in this film.

Fans questioned whether or not it made sense chronologically for Steve to stay in the past with his love, Peggy Carter, after putting the Infinity Stones back in their respective places in the the timeline, but one of the film's writers, Stephen McFeely, has some thoughts on Cap's ending. Speaking with Canada.com, Stephen McFeely referenced Captain America: The Winter Soldier (2014), which showed photos of Peggy's two children and mentioned but never named her husband, stating: "It depends on what story Marvel wants to tell going forward. I don't know if Marvel wants to tell any more Captain America stories or if Chris Evans is up for it. Do they want to tell an alternate timeline story? Chris and I are partial to the idea that Steve is part of a strange, unique time-loop where he has always been there. The husband that you very purposefully did not see at Peggy's bedside in Winter Soldier is Chris' Steve. We have always thought that he was her husband. The movies you have been watching follow a line where he always goes back. To be fair, not everyone agrees with us. I don't even know if Marvel agrees with us. But that's what we think."

The Russos' point to a scene in Captain America: The Winter Soldier. Rogers telling Natasha that he can't trust her if she stays in a morally gray existence as being key to her character and arc. Here he suggests giving up and moving forward, but she convinces him to instead stay the heroic course and find an answer. She discovers her own willingness to self-sacrifice in order to restore a "family."

The security guard at the storage facility where Scott Lang returns from the Quantum Realm is seen reading a book named "Terminal Beach", by J.G. Ballard. It was published in 1964 as a compilation of twelve sci-fi short-tales: "Terminal Beach" (hence the name), "A Question of Re-entry", "The Drowned Giant", "The Illuminated Man", "The Reptile Enclosure", "The Delta at Sunset", "Deep End", "The Volcano Dances", "Billennium", "The Gioconda of the Twilight Noon", "The Lost Leonardo", and finally "End-Game".

Robert Downey Jr. reflected on his and Chris Evans' ending on the MCU in the fall issue of Disney twenty-three magazine. "We had to get off. We opted to, and knew it was part of the job to get off the bus while it rolled on to other destinations," he explained. "There's something very sobering about it. I'm glad he and I will be there to welcome others as they retire their jerseys." Downey Jr added that he's "loathe" to talk about his "legacy" and making his mark, especially in comparison to Evans and fellow MCU star Mark Ruffalo. "I really don't need to look any farther than my co-stars. Mark Ruffalo is an activist, Chris Evans is a diehard American and proponent of true democracy," he said. "I don't really have the gumption, the skill set, the drive, or the humility either of those guys do." Downey Jr's impact in the MCU was recognised at the D23 Expo on Friday (August 23) 2019 when he was made a Disney Legend. And he marked the occasion by telling a hilarious story about being arrested on his first visit to Disneyland.

One of the shapes that Tony Stark tries when he is running simulations of his time travel 'GPS' - and eventually, the successful one - is a Möbius strip. This is a object that loops back on itself. This is a bit of foreshadowing of his death at the end of the movie, since this part of the MCU began with Iron Man (2008), and it ends with his sacrifice.

Tony and Thanos's final showdown is built up to parallel the fated duel of Thor and Cul Borson/Serpent in the "Fear Itself" comic storyline. Both Thor and Iron Man kill their nemeses, but they also die from mortal injuries.

The co-directors answerd fan questions on Twitter and, in one, a fan asked why it was okay for Smart Hulk to reveal the future to the Ancient One, if the Avengers weren't supposed to talk about the future in the past. It turns out, the explanation is pretty straightforward and makes a lot of sense in terms of the larger scope of the story. "That is a Back to the Future rule that is not applicable in our universe," Joe Russo said in directly answering the question. "We're playing by a different set of rules." However, even with the film playing by a different set of rules, Anthony Russo explained that there are some important reasons why talking about the future in the past can be problematic -- and why the Ancient One knowing was okay. "You may be thinking about the fact that Doctor Strange doesn't want to tell Tony about what timeline they're in as they're going into the climactic fight with Thanos," Anthony explained. "The difference between these two situations are when Smart Hulk is talking to the Ancient One, the Ancient One is no longer alive during the events that they're discussing whereas Tony is very much involved in the events he and Strange are talking about so there's a little bit of a distinction there." "And that's just really talking to someone about this prior to their death," Joe said, taking it a bit further. "You don't want to emotionally confuse them or create a situation where they no longer want to go through with what they are supposed to go through with." "Especially when your chances are one in 14 million," Anthony added. "You have to be very, very careful about not messing it up." That specific breakdown actually makes a lot of sense, especially if you go back and look at Tony Stark's (Robert Downey, Jr.) journey within Endgame. Tony establishes early on that preserving his "happily ever after" as it were -- his life with Pepper and his daughter Morgan -- is of utmost importance to him. While the possibility he won't survive the Time Heist is something that he clearly intellectually understands, it's also not something he likely sees as a tangible possibility -- or, at the very least, can't allow himself to consider. It is entirely possible that if Tony knew going into things that he was going to die in order for the team to ultimately succeed and save the universe, he would have opted out and thus ruin the one successful outcome out of 14 million possibilities. Narratively, there's also something to be said for the story value of withholding information about the future from those who will be part of it. One of the deeply emotional moments of Endgame for fans is getting to watch Tony realize that they are in the one and only successful outcome -- as well as the realization of what that means for him personally. It makes his "I'm Iron Man" snap even more moving, his sacrifice all the more heroic. "What's so incredible about Robert Downey and his performance -- and we think this is an awards-caliber performance -- is when he looks at Benedict in that moment, what you see happen on his face and the way he just drops his eyes and receives the information, it's because he knows he's the solution and the solution involves snapping his fingers -- he's going to die," Joe Russo explained to Backstory Magazine. "The thing he wanted to preserve two hours earlier in the movie is his relationship with his daughter, and he will have to sacrifice that in order to save everyone else."

Several elements are adapted from the comics for what happens to Captain America at the end of the film in regards to his decision to return to the 1940s and later appearance as an old man where he passes his shield and title to Sam Wilson. -"Ultimates" (2002): Adapts several elements of Bucky's Ultimate Marvel counterpart of living over several decades after World War II and later appearing in the present as an old man. -"House of M" (2005): Steve Rogers living the quiet life with Peggy Carter rather than being a superhero. -"The Tomorrow Soldier" (2014): After Steve Rogers becomes an old man, he passes on his shield and title as Captain America to Sam Wilson (Falcon).

In the scene in New Asgard based in Scotland, on the table next to Thor are a bottle of Irn Bru and the Scottish "delicacy" the deep-fried Mars Bar, which also features on an advert in Avengers: Infinity War (2018).

Tony's daughter after the time skip is named Morgan. In the comics, Tony has a rarely-appearing (male) cousin named Morgan Stark, who usually brings trouble with him whenever he shows up.

In the scene where Hulk and Rocket visit Thor in New Asgard, Korg from Thor: Ragnarok (2017) is seen playing Fortnite (2017) in the hut. Around the film's release, Epic Games launched a new crossover game mode based on it, similar to the tie-in event with Avengers: Infinity War (2018).

Thanos in both Avengers: Infinity War (2018) and "Endgame" has a left-handed gauntlet that carries the Infinity Stones, whereas Hulk/Bruce Banner and Iron Man/Tony Stark both use a right-handed gauntlet with the Infinity Stones, perhaps symbolizing their different ideologies.

The very last shot filmed for the movie was Stark's final snap while saying "I am Iron Man." It was a late addition to the film and added during re-shoots in January of 2019 at Raleigh Studios on a stage adjacent to the one on which Robert Downey Jr. screen-tested for the role twelve years prior.

Screenwriters Christopher Markus and Stephen McFeely revealed that it was Clint Barton who ended up dead in an earlier draft of the screenplay. "Jen Underdahl, our visual effects producer, read an outline or draft where Hawkeye goes over. And she goes, 'Don't you take this away from her.' I actually get emotional thinking about it," McFeely said. "And it was true, it was him taking the hit for her. It was melodramatic to have him die and not get his family back. And it is only right and proper that she's done," added Markus. As Professor Hulk (Mark Ruffalo) mentions near the end of the film, he really tried to revive Natasha when he had the six Infinity Stones in the Iron Man glove. But when a person dies for the Soul Stone (see: Gamora), they stay dead. "Her journey, in our minds, had come to an end if she could get the Avengers back. She comes from such an abusive, terrible, mind-control background, so when she gets to Vormir and she has a chance to get the family back, that's a thing she would trade for," continued McFeely. "The toughest thing for us was we were always worried that people weren't going to have time to be sad enough. The stakes are still out there and they haven't solved the problem. But we lost a big character -- a female character -- how do we honor it? We have this male lens and it's a lot of guys being sad that a woman died."

The song that plays when Steve Rogers is dancing with Peggy towards the end of the movie is the same song that's playing in Captain America: The Winter Soldier (2014) in the scene when Cap comes home and finds Nick Fury in his apartment.

Several Back to the Future Part II (1989) references can be seen in the return to the Battle of New York scene, including Tony Stark getting hit by the door Hulk swings open and the sunglasses worn by Thor. The scene mirrors Marty McFly trying to get the sports almanac back. Ant-Man further makes several "Back to The Future" references.

Rhodey's caution to Nebula before they enter the room for the Power Stone is a nod to Raiders of the Lost Ark where the idol was protected by a booby trapped floor that caused poisoned arrows to shoot from the walls; hence Rhodeys warning about arrows.

Tony leaving behind an epitaph in the form of a hologram recalls the time Iron Man fell into a coma but his consciousness was preserved as an A.I. techno-ghost.

Clint compares himself to Thanos against criminals; he later hands over the Stark Gauntlet unknowingly to 2014-Nebula. In the comics, Nebula steals the Infinity Gauntlet from Thanos's physical body after he has assumed the form of Eternity.

A monument honoring Tony Stark/Iron Man was erected in Forte dei Marmi, Italy following the beloved character's death The polished steel and brass statue photos of which have been shared to the r/MarvelStudios subreddit depicts Iron Man in his iconic, three-point "superhero landing" and stands over 13 feet high. It was designed by sculptor Daniele Basso for his "Oltre Verso" art exhibition at the Fortino Lorenese gallery in Forte dei Marmi. This homage to Tony Stark resides outside, in the middle of Via Carducci. The monument has been dubbed "Man of Steel," likely in reference to the materials used to craft it. It rests upon a white marble plinth, which features a dedicated plaque. When translated from Italian to English, the plaque loosely reads: "The first monument dedicated to Iron Man in the year of his death in the cinematic world, we celebrate Tony Stark as the man who dedicated his life's fortune to fighting for the ideals he believed in... reminding us that we are all the protagonists of our time - that the future of humanity depends on our decisions... that all of us must be heroes."

When Scott Lang is proposing the idea of time travel to Tony Stark, he uses the phrase "time heist". "Time Heist" is the title of an episode in the eighth season of Doctor Who (2005), a show about time travel. Karen Gillan, who plays Nebula in this movie, played a major character, Amy Pond, in several seasons of "Doctor Who".

With four simple words, Tony Stark revealed his secret to the world and gave 2008's Iron Man the perfect ending line. It's only fitting that he repeats the line in his final and greatest act as a superhero.

In the main-on-end credits montage, a total of fifty-four actors are credited, fifty-two of which have appeared in several films in the Marvel Cinematic Universe. Hiroyuki Sanada and James D'Arcy are the only two with one MCU film credit to their names, though D'Arcy was previously associated with the TV series Agent Carter (2015). Including mid/post-credits appearances: 2 - Angela Bassett; Linda Cardellini; Brie Larson; Michelle Pfeiffer; Robert Redford; Tilda Swinton; Tessa Thompson; Tom Vaughan-Lawlor; Taika Waititi 3 - Michael Douglas; Winston Duke; Frank Grillo; Danai Gurira; Pom Klementieff; Evangeline Lilly; Natalie Portman; Rene Russo; Benedict Wong; Letitia Wright 4 - Jacob Batalon; Dave Bautista; Chadwick Boseman; Josh Brolin; Bradley Cooper; Benedict Cumberbatch; Vin Diesel; Karen Gillan; Sean Gunn; Maximiliano Hernández; William Hurt; Chris Pratt; Paul Rudd; Zoe Saldana; John Slattery; Marisa Tomei 5 - Hayley Atwell; Tom Holland; Elizabeth Olsen; Jeremy Renner 6 - Jon Favreau; Tom Hiddleston; Anthony Mackie; Cobie Smulders 7 - Don Cheadle; Gwyneth Paltrow; Mark Ruffalo; Sebastian Stan 8 - Chris Hemsworth 9 - Scarlett Johansson 10 - Robert Downey Jr. Chris Evans and Samuel L. Jackson both hold the record for the most appearances in the MCU with eleven film each.

Natasha didn't get a funeral in "Avengers: Endgame" because audiences will see her again in her solo Black Widow movie. After the casualties of "Avengers: Infinity War" and the expiring contracts for actors, many fans braced for more deaths in "Avengers: Endgame". As most expected, the film served as the final chapters to Tony Stark aka Iron Man (Robert Downey Jr.) and Steve Rogers aka Captain America (Chris Evans). But, it also marked the end of Black Widow's time in the present day of the Marvel Cinematic Universe. Fans have asked why Natasha didn't get the same amount of screen time post-death as Tony did. Joe Russo previously suggested that the funeral happened off-screen and could be shown in a future MCU film. If that is the case, then his current explanation that Black Widow is the reason it didn't happen could indicate the solo film could show a spy's funeral.

The killing of Thanos at the beginning of the film is a callback to Tony Stark's promise to Loki in the first Avengers film: "If we can't save the Earth, you can be damn well sure we'll avenge it." This is exactly what happened in this film, with the added bonus of the restoration of the missing people and animals.

During the battle with Thanos before help arrives, Thor goes straight for Thanos's head, just as he was advised to in Avengers: Infinity War.

Jon Favreau, director of Iron Man (2008) and the person who started the MCU, is seen at Tony's funeral talking to Morgan. (Favreau plays the recurring role of Tony Stark's driver/bodyguard, Happy Hogan.)

"The tone at the end of the movie changes without this chance encounter," and that encounter is Stark running into his father Howard in 1970. "It's his final unresolved issue."

Right after the Time Skip, Natasha all but says to Steve that she's been married to the job for the past five years because she has nothing else in her life. This foreshadows what happens to her on Vormir with Clint.

In The Avengers (2012) Rogers accuses Stark of not being willing to sacrifice himself for the greater good. In the ending of that movie, he does, but being Stark, Tony squeaks by and lives. In Endgame he not only sacrifices himself, knowing the extreme damage done to the Hulk, but he intentionally gives his life in doing it, knowing he would not survive.

Bucky tells Captain America he's going to miss him even though he's only supposed to be gone for seconds, because he knows him well enough to realize that Steve is going to live his life out, and this is the last time he'll see him young.

Tony's snap with the Infinity Stones inadvertently fulfills Steve's order for him to "...turn it back or turn it to ash." from The Avengers (2012).

In a bit if foreshadowing, Dr. Strange tells Tony Stark that if he tells him the future it won't come true. This is true of Thanos, who has learned his future of both the snap and his death, neither of which comes true (or stays true) after her learns of them.

Scarlett Johansson opened up about Black Widow's heartbreaking death that took place in "Avengers: Endgame." "The finality of it was sad, but I was excited to die with honor," the actress said in a new interview with The Hollywood Reporter. "It felt in-character that she would sacrifice herself, of course for humanity but actually for her friends, for the people she loves," Johansson, who learned about her character's fate prior to filming 2018's "Avengers: Infinity War," told THR. "It was bittersweet."

When Scott Lang is listing movies with a time travel theme, he accidentally says Die Hard (1988). "Die Hard" star Bruce Willis did star in several time travel-themed movies, including The Kid (2000), Twelve Monkeys (1995), and Looper (2012).

Unlike Thanos, who saw a young Gamora after acquiring the Soul Stone, Barton didn't see Natasha after he got the stone. EDIT: Thanos does not see young Gamora after acquiring the soul stone in Infinity War. He sees her after the snap, after he's acquired all the stones.

There was a lot of conversation and thought as to what Stark would look like after the snap and before dying.

Hulk ends the film with his arm in a sling thanks to his use of the Infinity Gauntlet. At the end of the original "Secret Wars", Hulk also ended up with a broken limb, though in that case it was a leg.

It is the third Avengers movie to be released in the same year as a Quentin Tarantino movie: The Avengers (2012) and Django Unchained (2012) were both released in 2012, Avengers: Age of Ultron (2015) and The Hateful Eight (2015) were both released in 2015, and "Avengers: Endgame" and Once Upon a Time... in Hollywood (2019) are both being released in 2019. Actor Samuel L. Jackson had a role in at least the first five of these six films (although rumors have circulated that he will also have an appearance in "Once Upon a Time in Hollywood"), being a frequent Tarantino collaborator and playing Nick Fury in the MCU.

When Clint and Wanda reconnect after Tony's funeral, Clint laments the fact that Natasha may never know her sacrifice helped the Avengers win. Wanda reassures him by saying "She does. They both do." This is a silent acknowledgment of Vision.

Directors Anthony and Joe Russo reiterate the damage done to Smart Hulk when wielding the complete set of Infinity Stones is "irreparable" despite his advanced healing factor. "The Hulk has never come up against every Infinity Stone in a gauntlet, and the pure power of the stones. Thanos is nearly invincible, and he did not heal either," Joe Russo says in a Twitter Q&A hosted by Wired. "So, clearly, when you wield the full power of the Infinity Stone, it's irreparable damage to your being." Added Anthony Russo, "If it doesn't even kill you." Thanos and the gamma-powered Hulk survived only because of their incredible power; a third snap performed by Iron Man to obliterate Thanos and his army proved fatal for the fully human Tony Stark.

Brie Larson (Carol Danvers/Captain Marvel), Tom Hiddleston (Loki), and Samuel L. Jackson (Nick Fury) previously starred together in Kong: Skull Island (2017), along with fellow MCU veterans John C. Reilly (Rhomann Dey in Guardians of the Galaxy (2014)) and Shea Whigham (Roger Dooley on Agent Carter (2015)).

The moment of Tony looking out of the window was drawn out in order to hint that this may have been the death of Tony Stark.

When Tony finally decides to join the Time Heist, he lays his priorities out for Steve: Get back those lost if possible, protect what Tony's gained as a necessity, and "maybe not die in the process." Tony places the least priority on that last one, and will end the fight with a Heroic Sacrifice.

"Bringing people back from five years ago is a messy proposition any way you look at it," and that applies both to the logistics of the Marvel Universe and the logistics of human reality. What if someone disappeared while in a plane, do they return thousands of feet up in the sky? The Russo's don't answer this, but of course the answer is yes meaning that we really should have gotten a deleted scene of bodies falling from the sky at the end of the movie.

Akihiko, the Japanese gangster killed by Clint Barton (Jeremy Renner) as the rogue avenger Ronin, is played by Hiroyuki Sanada, who also played a Japanese ronin in the film 47 Ronin (2013).

Thor travels back to the events portrayed in Thor: The Dark World (2013). That film also featured Alice Krige, who appeared in the final episode of Star Trek: Voyager (1995) - also called "Star Trek: Voyager: Endgame (2001)" - as the Borg Queen. The story of that episode is an acknowledged influence on this film, and her own role strongly paralleled that of Thanos.

The Stark Gauntlet is analogous to the Odinsword/Odin-weapons as the Avengers' Infinity +1 Sword.

Stark uses his nanotech to steal the stones from Thanos' gauntlet rather than removing the whole glove. They don't explain why he would snap rather than simply use the power to freeze all of Thano's thugs or turn them into rabbits or whatever.

During Thor's breakdown of the Aether (which is nothing more than a long-winded ramble), he brings up his mother, which grinds his stream-of-consciousness speech to a halt as he thinks about her. Later on he manages to get that last moment with her and set things right in his head.

According to the Russos, Steve's ending was planned just three years ago, preceding the release of Infinity War. Believable enough, especially considering Infinity War and Endgame work as two parts to the same whole. However, when looking at previous film entries and interviews from the Russos, Markus and McFeely, it becomes clear that despite their assertions otherwise, Cap's ending was almost drastically different before those Infinity War plans. Right before Civil War dropped, Markus and McFeely gave an interview to ScreenRant. During this interview they were asked about Sharon Carter, a longtime Captain America character who was largely underutilized in the films. The duo seemed forthright on their assertion that Steve and Peggy's romance was hardly one to write home about. "They kissed once on a moving car with Tommy Lee Jones in the car. Not the sexiest situation you can have. So you know in a way people go, 'Ooh that's weird.' But when you think about it, one, she's her grand-niece. This isn't incest. This is 'You're vaguely related to a woman I once kissed,' said Markus. This is a stark contrast to the quotes the duo have been releasing since Endgame's success. In more recent interviews, the two have made claims ranging from "Steve was Peggy's unnamed husband in The Winter Soldier all along" to "Steve attended Peggy's funeral in Civil War." It's pretty obvious none of that was planned given their previous commentary (and their work on previous films). The tonal shift in their interviews between Civil War and post-Endgame is just too stark.

It only made sense that Iron Man would earn the most screen time in these adventures, as the entire Marvel Cinematic Universe was kicked off by Iron Man in 2008, with the character being the linchpin that held the entire MCU together. Additionally, the film served as his final entry in the series, though co-writer Christopher Markus previously revealed they had considered finding ways to let the character survive the ordeal. "We weren't there to just kill characters off," Markus shared with Canada.com. "We were told, 'If the story demands it, you can take people off the board. But if there's a good story to be told and no one dies, go ahead and tell that one too.'" He added, "In Endgame, we were trying to finish arcs and for Iron Man/Tony Stark to give up his life and sacrifice himself for the good of the universe seemed like a really good narrative closure for the billionaire playboy who had been learning over the course of several films (to be a better person)."

The near finality of Stark's death at the beginning of the film takes an emotional toll on the audience but this is mitigated by the logical assumption that he would somehow survive, which he does. This softens the blow when Stark actually dies, having prepared the audience. This lessens the sense that the story is over at that point, priming the audience for all the summing up that happens afterwards.

Steve Rogers was forever denied his dance with Peggy Carter at the end of Captain America; The First Avenger. But thanks to the magic of time travel, Steve finally got his happy ending, retiring to a quiet life and a good dance with his best girl.

The final time Thanos is seen, he gazes upon everything he's lost and wearily sits before fading into dust. That scene echoes a similar scene in Infinity War, as a triumphant Thanos sits to nurse his wounds and greet the coming sunrise.

The Russo's knew they needed two snaps and debated if the first should bring everyone back itself a detail that required debate as how does that work anyway? and then have Thanos arrive to attack everyone, but they realized that would keep them from the big hero beat of the cavalry's arrival. The big clue that the snap worked is that Clint's wife calls him on the phone, "her cell service still active."
