A smash hit for Universal Pictures, 2015's Jurassic World revived the long-dead franchise, and its sequel coming out in a year, aims to build on its incredible success. However, Jurassic World 2 is looking to the past for inspiration -- it's been revealed that many lines of dialogue in the sequel's script are ripped straight from the novel from which the series is based, by Michael Crichton (Westworld).

Speaking with MTV News (via ScreenRant), co-writer of Jurassic World 2 and the first film's director, Colin Trevorrow, revealed the inspiration he took from the novel, in addition to singing praises of Jeff Goldblum, who will make a return as fan-favorite character Dr. Ian Malcolm.

“You know, I did rely on [Michael] Crichton for a lot. I used a lot of Crichton dialogue. Maybe one of my highlights of this whole process is Goldblum. Jeff Goldblum called me – and I’m not going to do an impression – but he was like, ‘Look, I’ve added a couple of things, and I thought I’d perform it for you.’ [Laughs] Oh, great, okay. So, we sat on the phone for an hour as he ran these lines, and I talked about it. And, I mean, that’s – it was almost better than being there on set. It was great.”

Discussing his return last month, Goldblum said, “I like my character...I think my character is a saucy, sassy man of some integrity and deep thinking. And of course, that whole world continues to be popular, slam-bang, top entertainment. I talked to the director, J.A. Bayona, over the phone. I enjoyed his movie The Impossible with Naomi Watts, and he’s something else. I didn’t realize he was a good friend of a friend of mine, a director I worked with a while ago in Spain named Fernando Trueba, who’s just fantastic. Knowing that the two of them are brethren and brotherly in their friendship makes me feel very good, too. Even though some might say it’s popcorn-y entertainment (top-notch, of course), in our conversation he was very focused on the serious issues of greed as it oftentimes comes up in those movies, and the marvels of science and reason and the very fascinating point at which our species finds itself both in real life and in this imaginary world too. I’m very interested in that myself, so I’m looking forward to this. I’ve got a few things to do. I’m nothing if not conscientious, so I’m enjoying working on it every day.”
