In a interview with Collider in November 2014, Guillermo del Toro talked about setting the stage for Pacific Rim 2 (2017), stating, "It's a few years after the first one. It's not an immediate follow-up. It is the world having been freed of Kaiju, what happens to the world after -- what happens to the Jaeger technology once the Kaiju are not a threat. It's quite a jump." del Toro did not return to direct Pacific Rim: Uprising (2018).

Guillermo del Toro stepped down as director in order to direct The Shape of Water (2017) instead, which went on to win the Academy Award for Best Picture.

During an interview with Collider in November 2014, Guillermo del Toro stated that Charlie Day's character, Dr. Newton Geiszler, and Burn Gorman's character, Gottlieb, are in the sequel with the respective actors (Day and Gorman) reprising their roles from Pacific Rim (2013) for the sequel. del Toro commented on it, stating, "Yes. It's quite a different movie from the first one in that, but I think that two of our main characters like in the first one are Burn and Charlie. They are really, really -- I mean, honestly, they are probably the guys I have the most fun writing, along with Hannibal Chau, so just from a purely selfish drive, I like writing them. I love writing for Charlie and Burn. I mean, [Hunnam] in Crimson Peak (2015) for that reason, because I love working with him."

James Gunn filmed a cameo as a DJ, but it ended up being deleted from the finished movie. Gunn joked on Twitter that the scene was omitted so that his character could be saved for his own spin-off movie.

It was reported in 2016 that Charlie Hunnam would not be returning as Raleigh Becket.

When Newton activates the drone subroutine, the screen displays the name of the protocol as CMD LIMA VICTOR 426, as a nod to the movie Aliens, where most of the action takes place on a moon called LV-426.

Bracer Phoenix was just the second Mark-5 Jaeger, with the first being Striker Eureka. All of the other Jaegers, (Gipsy Avenger, Saber Athena, Titan Redeemer, Guardian Bravo) are Mark-6's.

Raijin is only the second Category 5 Kaiju, after Slattern from Pacific Rim (2013). The other two are Category 4s.

Guillermo del Toro did not return to direct the sequel. However, he did produce and write the story for the movie.

Pacific Rim: Uprising (2018)'s release date was pushed back from August 4, 2017 to February 23, 2018. It was later pushed back another month to March 23, 2018.

Director's cameo: 1:26:06. His face appears on the billboard that the jaeger lands on.

Steven S. DeKnight's first blockbuster movie as director after writing and directing several television show episodes, such as Daredevil and Smallville.

Bracer Phoenix was the second Jaeger to have three pilots, after Crimson Typhoon from Pacific Rim (2013).

Warner Bros. Pictures, who produced the first film with Legendary Pictures until 2014, released this film internationally. Universal, who collaborated with Legendary currently, distributed the film domestically.

Unlike the first Pacific Rim (2013), this film does not include an end credits scene.

In the scene where Jules Reyes tackles Nate Lambert, actress Adria Arjona performed the stunt herself, as seen on The IMDb Show (2017).

Composer John Paesano recorded a score in December 2017 at the Synchron Stage Vienna. However, it was never used.

The film reunited Spartacus: War of the Damned (2010) and Spartacus: Gods of the Arena (2011) cast members Steven S. DeKnight, Nick E. Tarabay, Dustin Clare, Daniel Feuerriegel and Shane Rangi.

The Kaiju that Gipsy Avenger and Bracer Phoenix fight is named Raijin, which sounds similar to Raiju, the name of a Category 4 Kaiju that was killed by Gipsy Danger in Pacific Rim (2013).

The voice of the system inside Gypsy Avenger sounds very much like the voice of GLaDOS (Portal, Portal 2, voiced by Ellen McLain).

The conscripted scavenger character, Amana Namani, played by actress Cailee Spaeny, innovatively pilots her self-made Jaeger, that has the call sign "Scrapper," a term very aptly used from orthodox western boxing, which describes a fighter that is small in stature but has strong willpower. These attributes are frequently shown or referenced during the movie.

This was the first "Pacific Rim" feature to be shot in Panavision (anamorphic) 2.39:1, a format favored by DP Dan Mindel.

In just three days, it became the 11th highest grossing film of 2018, grossing $150.5 million as of March 25.

The movie featured a soundtrack titled 'Daddy Yo' by Nigerian artist 'Wizkid' off his 'Sound from the other side' Album.

This is the second franchise for John Boyega and Scott Eastwood: Boyega is main star in the third Star Wars trilogy (Star Wars: The Force Awakens (2015), Star Wars: The Last Jedi (2017) and Star Wars: Episode IX (2019)), meanwhile Eastwood appeared in The Fate of the Furious (2017).

Despite being the hero of this film's predecessor, Raleigh Becket is only mentioned once in this movie, and his fate remains unknown.

The kaiju's long-running plan to get to Mt. Fuji is a nod towards the many decades of kaiju-movies that involved monsters attacking Japan again and again, seemingly for no reason.

In the final battle between Kaijus and Jaegers, Unicorn Gundam statues and Anaheim Electronics' names can be seen on the building.

While Jake is paying his respects to Mako in a Jaeger pilot hall of fame, Lt. Sasha Kaidonovsky and Stacker Pentecost can also be seen on the wall.

Director's commentary: the bots that stitch MegaKaijju together are called "rippers" because they rip apart the kaiju to create a new form. The director also says he had no idea how to do this so it is very hard to see.

The codename of three kaijus combination seen on Newt's handheld tablet screen, is Megakaiju. It refers to combination of Power Rangers' zords forming bipedal mecha, Megazord.

Guardian Bravo was the only Jaeger not destroyed by the Mega Kaiju. While it was heavily damaged after being flung into several skyscrapers, its body remained mostly intact.

If you look carefully at the scene inside Scrapper, you can see the same red cable as the one in Obsidian Fury that Amara deduces was manufactured by Shao.

Despite being heavily advertised in the trailers, Obsidian Fury only appears in two scenes. In Sydney where it kills Mako and fights Gipsy Avenger, forced to retreat after other jaegers were about to be deployed, and in Siberia where it destroys an old jaeger factory, fights with Gipsy Avenger again and has its power core ripped out.

Of the four Mark-6 Jaegers, Titan Redeemer is the only one to not participate in the fight against Raijin, Hakuja, and Shrikethorn due to it being destroyed during the kaiju controlled jaegers attack on the shatterdome.

The giant kaiju made of the several smaller ones resembles Slattern, the largest Category 5 kaiju from Pacific Rim (2013). They used their tails to damage Jaegers. Slattern used its tail to hit Striker Eureka's chest and to stab Gipsy Danger's back while the giant kaiju used its tail to rip Saber Athena's leg off and throw it into a building. The kaiju also used their environment to damage Jaegers. Slattern shoved Striker Eureka into massive ocean rocks, while the giant kaiju shoved Guardian Bravo into several skyscrapers.

For Gispy Avenger's Chain Sword, unlike Gipsy Danger, in the first film, who was able to activate 2 Chain Swords, Gipsy Avenger, on the other hand, appears to only have one and can only be available to activate on the Jaeger's left arm.

November Ajax is one of the three jeagers who have only be shown once in action when it was chasing the escaping Amara and Jake in Amara's homemade jeager, Scapper.
