Guillermo Del Toro, in an interview with Collider, stated plans for film of Pacific Rim 2 and that he is looking for it to lead into Pacific Rim 3. Del Toro reiterated how the sequel will be a different experience, and stated the quote below,
“Some of your favorite characters come back, some others don’t because we have decided that we’re going to shoot ambitiously and say ‘Let’s hope we have three movies,’ so some characters come in at the end of the second, hoping that it will ramp up on the third one.”
With Godzilla planned as a trilogy, and the serious possibility Skull Island could get a sequel if it does well, we could have a steady stream of kaiju movies. One negative is the trilogies aren't something that seems to happen with Del Toro (Hellboy). More as we get it.
