Travis Beacham and Guillermo Del Toro are writing the script. As of now, the film has not been officially greenlit.
Source: IGNIGN: Do you think with something like Pacific Rim 2, can the Blu-ray make or break a sequel?
GDT: No, we are writing the sequel. Travis Beacham and I are writing, so that is active. The decision to green light or not, that’s definitely above my pay rate.
IGN: Right, that’s definitely a film we hope to see. Obviously, you’ve already built this universe. So for someone like me looking from the outside it seems like in a lot of ways it would be easier to make the sequel, because so much of this infrastructure already exists. Does that make sense?
GDT: It does. To me, what was beautiful and flattering was how people saw the movie not once or twice but three, four times or more. People that love it, love it with great passion. So I would love to continue telling stories about that world.
