<P> On September 10, 2013, Universal Pictures confirmed the film would be titled Jurassic World and would be released on June 12, 2015 . Trevorrow chose to rename the film from its previous title, Jurassic Park IV, to differentiate it from previous films in the series . Trevorrow also said that within the story, "if you named a theme park' Jurassic Park' after the disaster that had happened it would be a horrible PR mistake ." By February 7, 2014, Legendary Pictures had agreed to co-finance the film, and provided about 20% of the budget . China Film Group has been reported as also having financed the film . Thomas Tull of Legendary Pictures served as executive producer for the film with Spielberg . </P> <P> Spielberg had three ideas that he wanted Jaffa and Silver to implement into the script: a fully functioning dinosaur theme park, a human who has a relationship with trained raptors (from Sayles' earlier draft), and a homicidal dinosaur that escapes and has to be stopped . Jaffa and Silver's draft, titled Jurassic Park IV, included an opening scene set in China, where the fossilized remains of a new dinosaur species would be discovered by a Chinese female paleontologist . In the draft, the remains would be stolen by a corporation with malicious intentions, ultimately leading the paleontologist and her two sons to visit Jurassic Park . Jaffa and Silver worked on the script for approximately a year, with input from Spielberg . </P> <P> After the film was delayed in May 2013, Trevorrow and Connolly continued rewriting the script during the summer, and worked with Spielberg during that time to perfect it . Throughout the writing period, Trevorrow, Connolly and Spielberg had many meetings to discuss the film's story . David Koepp also met with Trevorrow and Connolly to advise them on the script . Koepp had previously written the first two films in the series, but at some point declined an offer to write the fourth film, as he felt that he had nothing left to contribute to the series . Trevorrow said that perfecting the script was the hardest part because Jurassic Park films "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 ." </P> <P> To determine the film's story, Trevorrow and Connolly discussed world events that had occurred over the previous two decades; Trevorrow said that two main ideas emerged: "One was that money has been the gasoline in the engine of our biggest mistakes . If there are billions to be made, no one can resist them, even if they know things could end horribly . The other was that our relationship with technology has become so woven into our daily lives, we've become numb to the scientific miracles around us . We take so much for granted . (...) We imagined a teenager texting his girlfriend with his back to a T - Rex behind protective glass . For us, that image captured the way much of the audience feels about the movies themselves .' We've seen CG dinosaurs . What else you got?"' Trevorrow also said Jurassic World was inspired by a quote from Ian Malcolm in the first film: "You stood on the shoulders of geniuses to accomplish something as fast as you could, and before you even knew what you had, you patented it, and packaged it, and slapped it on a plastic lunchbox, and now you wanna sell it ." Trevorrow said Malcolm's quote inspired the large amount of product placement in the film . </P>
