It's still more than a year away but the hype on "Jurassic Park's" fourth installment is getting louder as the original cast (Sam Neill who plays Alan Grant, Jeff Goldblum who plans Malcolm and Laura Dern who plays Ellie Sattler) were written out of "Jurassic World."

"I know a lot of fans want to see the original characters back," says director Colin Trevorrow. "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 with the three central characters gone, original cast BD Wong who plays scientist Henry Wu will reprise his role, and this time he will be appreciated for all his work and sacrifices in Jurassic Park. "He spent two decades living in Hammond's shadow, underappreciated. We think there's more to his story," revealed Trevorrow of his plans of enhancing the role of Wong.

Penned to be released for June 2015, "Jurassic World" is still under the supervision of its original director Steven Spielberg who will produce the dinosaur-park franchise. With the dinosaurs' continuous evolution, Trevorrow also revealed when news broke out about feathered dinosaurs that he sticking with the initially created rules than try to keep pace with second-guess reality.

JP4 also insist the upcoming dinosaur movie is not a "reboot," but a continuation of the previous movies. With Sam Neill out of the picture, Chris Pratt is cast as a lead playing the role of Owen, a rugged ex-military who will finds himself in the middle of a dinosaur-filled park.

"Jurassic Park was really kind of my Star Wars. I lined up at the theatre to see it, I saw it opening night, I saw every sequel, I've seen it a whole bunch of times..." says the "Zero Dark Thirty" actor in an interview posted in RadioTimes.com. "For me that was my big movie, I think I was 13 or 14 when it came out, and so it's a big deal for me to be any part of that, let alone this part I'm going to be playing. I'm thrilled about it."

The movie's location will be in Hawaii's Oahu and Kauai, before they will move their production set to Lousiana. "Jurassic World" will also star "Mandela: A Long Way to Freedom" actor Idris Alba and Bryce Dallas Howard.
