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.
Guillermo del Toro during an interview with Collider in November 2014, stated that Charlie Day's character Dr. Newton Geiszler & Burn Gorman's character Gottlieb are in the sequel with the respective actors (Day & 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, [Burn's] in Crimson Peak (2015) for that reason, because I love working with him."
