"Jurassic World" is upping the dino drama in the 2018 sequel, making it more and more difficult to hold onto your butts. Colin Trevorrow directed the 2015 film, and he's involved in "Jurassic Park 2" but -- since he's busy with a little indie film called "Star Wars: Episode IX" -- he passed the directing torch to "A Monster Calls" director J.A. Bayona.

Trevorrow and (briefly) Bayona recently had a great interview with the Jurassic Outpost podcast, teasing what's ahead in the sequel. Here are some highlights from the full chat, which you can listen to below.

• "Jurassic World 2" does have a title, the directors revealed, but they wouldn't share it or reveal when it would be made public.

• Spanish director Bayona is known for his horror films, and Trevorrow hinted to that influence in the "Jurassic World" sequel: "It will be more suspenseful and scary. It's just the way it's designed; it's the way the story plays out. I knew I wanted Bayona to direct it long before anyone ever heard that was a possibility, so the whole thing was just built around his skill set."

• Trevorrow noted that the kids who saw "Jurassic World" will be three years older by the time the sequel comes out. This is about making the story grow up for them, which is part of why he brought in a horror director. He said the structure of "Jurassic World" was about getting bigger and bigger as the story progressed. This sequel is inspired by the structure of the original "Jurassic Park."

• Bayona said of the sequel "I was very surprised by the story. ... There are things you really don't expect and it is very exciting."

• A real-world theme of the movie is "a mistake made a long time ago just can't be undone. ... You can't put it back in the box."

• Trevorrow said the movie is about our relationship with animals, and how we share the planet with other living things. Jurassic Outpost noted there's mention of militarization in the sequel, but there's also mention of open source and humans living along dinosaurs, with Trevorrow favoring the latter for the sequel's story.

• Trevorrow said "Jurassic World 2" is "built upon the concepts and stories" created by author Michael Crichton's novels. Trevorrow: "'Jurassic World' had to restart the engine. This movie has to prove it has a reason to exist." He added that it doesn't need to be "bigger," and it's not about "bigger better dinosaurs" or "bigger action sequences."

• Asked how much he had planned for the trilogy when making "Jurassic World," Trevorrow said, "I knew the end. I knew where I wanted it to go."

According to Collider, pre-production on "Jurassic World 2" is continuing in London, while Trevorrow works on early development for Episode IX and Bayona does press for "A Monster Calls."

"Jurassic World 2," which will eventually be called something else, is scheduled to open in theaters June 22, 2018.
