In een interview sprak regisseur Guillermo del Toro over Pacific Rim 2. Hij maakte bekend welke personages terug zullen keren en sprak over de tijdlijn van de film:
“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.”
Personages die terugkeren zijn Charlie Day en Burn Gorman: “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, [Burn’s] in Crimson Peak for that reason, because I love working with him. You’re gonna get a lot of that, but the Kaijus are very different and you’re gonna see a very different type of the robots I think. It’s gonna be quite a different adventure.”
