Jurassic World Director Colin Trevorrow On the New Dinosaurs

In a new interview with Empire, Jurassic World director Colin Trevorrow says that he's "comfortable" in "Crazytown," a headspace he needs to be in to make a sequel to Jurassic Park and to deal in the fantastical ideas of that world.

He also addressed questions about the never-before-seen dinosaurs -- and the rumored "D-Rex," the fictitious dinosaur genetically-engineered to serve as the film's main antagonist.

"There is no shortage of awesome [real] dinosaurs. We could have populated this entire story with new species that haven't been in any of these movies," Trevorrow said. "But this new creation is what gave me a reason to tell another Jurassic Park story. We have the most awe-inspiring creatures to ever walk the Earth right in front of us, but for some reason that's not enough. We're always hungry for the next thing, and those who profit from it are always looking to feed that hunger. The focus groups want something bigger than a T-Rex. And that's what they get."

Of course, fans who watched the trailer also saw the mosaurus, a massive, underwater beast who eats great white sharks.

"The idea came out in one of our first meetings," the director said. "I didn't know if Steven [Spielberg] and Frank [Marshall] had considered an underwater reptile, so I pitched the mosasaurus and went off on the idea."

He added (of the shark), "I thought it would be cool if we had this massive animal and the park used one of our most fearsome modern predators as food. There could be a whole other facility where they used shark DNA to mass-produce them to feed the bigger beast. It's a bonkers idea, but I'm comfortable going to Crazytown, because I used to live there when I was a kid."

Jurassic World is due in theaters on June 12.
