David KoeppThe Jurassic World Rebirth was one of the most anticipated films of the year. The movie stars Scarlett Johansson, Jonathan Bailey in lead roles. The film picks up five years after the events of Jurassic World: Dominion, when the planet's ecology has proven largely inhospitable to dinosaurs. Those remaining live mostly in isolated equatorial environments — among them three colossal dinosaurs whose DNA may hold the key to a life-saving drug. The film is receiving all the love after its release and the writer has now revealed the reason behind making this one 'less goofy.' Jurassic World Rebirth Writer Reveals What's New In The Film Screenwriter David Koepp, in a recent interview, shared, "I can only go with what works for me. Whether it works or doesn’t for others, that doesn’t matter. You have to be sincere … You can only write what you can write." Talking to The Hollywood Reporter, David said, "What I was struck by was that every three movies there’s an opportunity to change the tone, characters and ideas. The first Jurassic Park was an incredible feat of imagination. All these movies exist because Michael Crichton had a genius idea, right? The first Jurassic World, okay, that was also a great imagining. So this felt like a license to start with new people and a tone I was comfortable with." Further, he added, "But what was more important was I re-read both of Crichton’s novels — Jurassic Park and The Lost World. Because I was like, 'How am I going to come up with stuff that feels new? I’ve done this twice, but it’s been a while.' When I re-read the books, I was like, 'Oh, I remember this feeling.' The books are different in tone than the movie Jurassic Park because Crichton and Spielberg are very different people with different worldviews." It's Not Quite As Dark: David Koepp "[With Jurassic Park], we did something that was not quite as dark, and certainly hoped it was funny and but still had to be grounded in real science. As I was rereading the novels, I started taking tons of notes, because I was like: It’s all still here." "So, I felt like in the last film, in particular, they took that idea all the way. Dinosaurs were nesting on the Chrysler Building and renting apartments downtown. I didn’t have a single idea about where to go with that. But I wanted to respect what occurred in the first six movies, because I hate when you watch a franchise movie," quoted the screenwriter. "Then, in re-reading the books, I found the perfect justification. There’s a great speech which I just popped into the script, which was that we think these things are going to live here now, but we forget that this is a different planet. Our landscape is completely different except this narrow band where the environment is somewhat similar to what it used to be [where dinosaurs can survive]. So let’s make dinosaurs exotic and special so that we have to go seek them out instead of, you know, fighting with them over a cab," he concluded.
