Ever since Jurassic World was first announced, fans have been wondering if any of the Jurassic Park cast members will be coming back. Director Colin Trevorrow confirmed that one of the original actors will be making a return, although it might not be someone you expect.

Here's what the filmmaker had to say in an interview with IGN.

"I know a lot of fans want to see the original characters back. They're iconic. But I respect those actors too much to shoehorn them into this story for my own sentimental reasons. Jurassic Park isn't about the bad luck of three people who keep getting thrown into the same situation. The only reason they'd go back to that island is if the screenwriters contrived a reason for them to go. But there is a character from the first film who makes sense in our world. This hasn't been announced yet, but B.D. Wong will be returning as Dr. Henry Wu. He had a much larger role in the original novel, he was the engineer of this breakthrough in de-extinction. He spent two decades living in Hammond's shadow, underappreciated. We think there's more to his story."

B.D. Wong's Dr. Henry Wu didn't appear in the Jurassic Park sequels The Lost World: Jurassic Park or Jurassic Park III, so it will be interesting to see how he fits into the Jurassic World story line. He joins a cast that also includes Chris Pratt, Idris Elba, Bryce Dallas Howard, Ty Simpkins, Nick Robinson, Vincent D'Onofrio and Irrfan Khan.

This adventure marks a huge leap in scope from the filmmaker's directorial debut, Safety Not Guaranteed. When asked what the biggest challenge was so far, the filmmaker revealed that crafting the script with Derek Connolly was the toughest part of production, while discussing the decision to delay the movie from its original 2014 release date.

"Getting the script right was the tough part. There are a hundred different ways to tell any story, finding the right one takes persistence. Jurassic Park movies don't fit into a specific genre. They're sci-fi adventures that also have to be funny, emotional and scary as hell. That takes a lot of construction, but it can't feel designed. The characters have to be authentic, the situations real. Derek [Connolly, co-writer on the film] and I started with a blank page and worked all the way through the summer. The process got easier when we decided not to rush to meet that 2014 release date. There just wasn't enough time. Steven (Spielberg) had the foresight to make that call, the studio was supportive, and I couldn't be more grateful."

The director also offered new insight into the characters portrayed by Chris Pratt and Bryce Dallas Howard.

"He's a classic hero in a very modern context. He's the guy who will get you through the jungle alive - but like Malcolm, Grant and Sattler, he's an expert in a scientific field that's connected to our story. The character allows us to explore some new ideas about our relationship with these animals, without losing the humor and sense of adventure. He's a great contrast for Bryce Dallas Howard's character, who starts off very corporate, very controlled. Until the running and screaming starts. Then they need each other."

When asked how Jurassic World will differ from the previous Jurassic Park movies, Colin Trevorrow revealed that there will be a lot of new ideas, but the spirit of the original will remain.

"I'm not on a mission to separate this film from the ones that came before. That will happen naturally - I have different instincts. But, like a lot of people my age, I grew up on Amblin movies. They're a part of who I am as a filmmaker, and arguably as a person. This film will have a lot of new ideas in it, but I think the spirit will be familiar. It will have an old soul."

Unlike most modern movies that are shot on digital cameras, the filmmaker revealed that Jurassic World will be shot on film, in a very unique aspect ratio.

"We're shooting 35mm and 65mm film. We're also using an aspect ratio that hasn't been seen theatrically in a very long time. The movie will be presented in 2 to 1. It's basically a middle ground between 2.35 and 1.85. It allows us enough height to fit humans and dinosaurs into a single frame, without giving up that sense of scope. It's very close to the ratio of the digital IMAX screens, so it will look great in large format. I think other filmmakers will want to give it a try when they see how it looks. It's very comfortable."
