James Gunn revealed that he and Kevin Feige wanted David Bowie to appear in a cameo before his death on January 10, 2016.

This sequel was announced a week before the release of Guardians of the Galaxy (2014) at San Diego Comic-Con 2014.

In an interview, James Gunn said that most of the questions will be answered in this film that remained unanswered in the first.

According to Chris Pratt, the film's script helped him come to terms with the death of his father.

Unlike the last film where it was just his voice, Vin Diesel will also provide motion capture for Baby Groot.

Nathan Fillion plays actor Simon Williams (seen in movie posters). In the comics, Simon Williams was Wonder Man, an Avenger who had a very successful side career as a Hollywood action star who did his own stunts.

It is rumored that Beta Ray Bill will appear in this film. Bill is also rumored to appear in Thor: Ragnarok (2017), and later show up to help the Avengers in Avengers: Infinity War (2018).

After many rumors, Karen Gillan reprised her role as Nebula without shaving her head.

Gary Oldman, Viggo Mortensen, Christoph Waltz, Christopher Plummer, Max von Sydow, and Liam Neeson were considered for the role of Ego.

James Gunn clearly stated that this sequel won't set up Avengers: Infinity War.

Chapter Three of Phase Three in the Marvel Cinematic Universe.

Originally set for a July 2017 release, but was pushed up to May 5, 2017.

In an interview for the film, Karen Gillan explained that Nebula "is a pretty angry woman, with some daddy issues and that, in the second movie, we're going to start to see how much pain her father actually caused her, and we're going to delve right into the relationship with her sister Gamora. I think we might even feel a tinge of sympathy towards her this time."

Dave Bautista's Drax makeup took only 90 minutes to apply, down from four hours for the first film. However, he would have to sit in a sauna at the end of the day to get the makeup off.

According to the VFXperts, Ego's planet VFX is comprised of a trillion polygons, and is considered to be the biggest visual effect ever made.

The teaser poster is a parody of the Ramones' album cover, Rocket to Russia.

Chris Pratt said that he found the workout regimen for his shirtless scene much easier compared to the first film, because he was already in great shape going into the film. For Guardians of the Galaxy (2014), Pratt was sixty pounds overweight when he started working out. But for this film, however, he said he had maintained his buff physique acquired from the first film.

The film's subtitle is a nod to Star-Lord's Awesome Mixtape Vol. 1 tape from Guardians of the Galaxy (2014).

Prop master Russell Bobbitt had difficulty finding the cassette decks used in the first film and all of the Sony Walkman headsets they found were broken. Bobbitt contacted Sony to see if they had any available for filming, which they did not, so he eventually created six from scratch.

On March 23, 2016, Chris Pratt announced a fundraiser to help support the Lake Stevens' Boy's and Girl's Club, from where he grew up. By donating, you would get a chance to visit Pratt, and eat lunch with him on the set of this film.

Matthew McConaughey was considered to play Ego, but passed on the role.

According to James Gunn, John C. Reilly couldn't reprise his role as Corpsman Dey, due to scheduling conflicts.

This will be the first film shot on RED's WEAPON 8K digital camera. It is the digital equivalent to VistaVision, a higher definition 35mm format developed in the 1950s.

There were strong refrences of the superhero Nova in Guardians of the Galaxy (2014), and it was believed he would appear in the sequel, but director James Gunn said he has no plans to bring the character to the big screen.

Nathan Fillion, who plays Simon Williams in this film, played a different character (voice only) in Guardians of the Galaxy (2014).

As Groot only communicates with the phrase "I am Groot" in different inflections, James Gunn created a "Groot Version" of the script for himself and Vin Diesel, which contains each of Groot's lines in English

Prop master Russell Bobbitt created a 1:1 scale model of the 10-inch (25 cm) Baby Groot for filming to use as a lighting reference, and sometimes puppeteered against the actors during the filming.

It was announced on June 29, 2015, that the title would be "Guardians of the Galaxy Vol. 2."

James Gunn went on record in an interview that he wants to give Nebula her own spin-off movie.

Kurt Russell has appeared in many Disney films over the past fifty-one years. Guardians of the Galaxy Vol. 2 (2017) will be his first Disney film, and superhero film, in twelve years. Excluding Sky High (2005).

Cast members Kurt Russell and Sylvester Stallone previously worked together in Tango & Cash (1989).

Fifth collaboration between James Gunn and Michael Rooker. The other three films were Slither (2006), Super (2010), Guardians of the Galaxy (2014), and the Belko Experiment (2016) - which Gunn wrote.

James Gunn brought in fractal artist Hal Tenny to help design Ego's planet form.

Chris Sullivan's Taserface makeup took 2.5-3.5 hours to apply,

Karen Gillan went on record in an interview, saying that Guardians of the Galaxy Vol. 2 (2017) will be better than the first movie.

Vin Diesel and Kurt Russell appeared in Furious 7 (2015) and The Fate of the Furious (2017).

In the second trailer, The Sweet's "Fox on the Run" plays in the background. In one of the Suicide Squad (2016) trailers, The Sweet's song "Ballroom Blitz" plays in its background. This is a coincidence, because both songs appeared on the same album and Suicide Squad is also DC's answer to Marvel's Guardians, furthering the connections and coincidences.

Kurt Russell and Michael Rooker appeared together in the film 'Tombstone' (1993)

Sylvester Stallone is the second Expendables actor to appear in the Marvel Cinematic Universe. Mickey Rourke was the first.

The actress, Laura Haddock, who plays the character Meredith Quill, Peter Quill's mother also appeared in Captain America : The First Avenger, as a fan of Captain America.

Michael Rooker and Sylvester Stallone previously worked together in 'Cliffhanger' (1993)

Dave Bautista was a villain in the 2015 James Bond movie Spectre and plays a character named "Drax" in this movie, which was the name of the main villain in the 1979 James Bond movie Moonraker.

When James Gunn was writing the script for the movie, and proposed the idea of Ego the Living Planet being Star-Lord's father, Marvel had told him that they didn't have the rights to Ego, whose rights were with 20th Century Fox, because of his ties to the Fantastic Four and Silver Surfer franchises. Since Gunn did not have any other characters in mind for Star-Lord's father, he had to ask Fox if he could use the character. Fortunately, Fox agreed to let Marvel have Ego, in return for Fox having more creative freedom regarding Megasonic Teenage Warhead's set of superpowers in Deadpool (2016).

James Gunn wanted to feature cosmic entity/Guardian member Adam Warlock in the film, but decided to keep him for Guardians of the Galaxy Vol. 3 as he felt this film already had too many characters.

In Guardians of the Galaxy (2014) a cocoon is seen in the Collector's collection. This cocoon is rumored to contain Adam Warlock, who is a member of The Guardians in the comic.

James Gunn described making Ego as Star-Lord's father a continuation of exploring the personal side of the Guardians: "If a raccoon could talk, and shoot a machine gun, how could that be? Answering that question ended up being the entire foundation of the first film. There's a sadness in these characters: Rocket was an animal experimented upon and torn apart; Groot has far more in common with Frankenstein's monster than with Bugs Bunny. Ego is an even more ridiculous character. But if a planet was alive, how could that be? And how could it father a child? Nova Prime said about Peter's father in the first film is that he is something ancient and unknown. And being a cosmic being, alone for eons, is even more lonely than being the universe's sole talking raccoon."

Features 5 post credit scenes

At Yondu's funeral are his old friends Charlie-27, Starhawk, Martinex and Aleta. In the Marvel comics all of them were former members of the Guardians of the Galaxy.

The Guardians of the Galaxy will return in Avengers: Infinity War (2018).

Stan Lee: An astronaut on the moon.

Although his parentage was changed for the film, Peter Quill being of Celestial descent is (possibly) consistent with his comic book origin, since it's been suggested in the comics that he might be the grandson of Eson the Searcher.
