In a interview with Collider in November 2014, Guillermo del Toro talked about setting the stage for Pacific Rim 2 (2017) in 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."
It was reported in 2016 that Charlie Hunnam would not be returning as Raleigh Becket.

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, [Burn's] in Crimson Peak (2015) for that reason, because I love working with him."
