On June 3, 2015, Trevorrow stated that Jurassic World left story possibilities open for the sequel's director that could potentially allow the film to take place in a different location, rather than on an island. Trevorrow hinted that the next film could involve dinosaurs being used by other companies for non-entertainment purposes, possibly in agriculture, medicine, and war: "I really like the idea that this group of geneticists aren't the only people who can make a dinosaur [...] when you think of the differences between Apple and PC the minute something goes open-source, there are all kinds of entities and interests that may be able to utilise that technology."[55]
On June 8, 2015, Frank Marshall met with Trevorrow and Universal Studios to discuss a Jurassic World sequel.[56] Later that month, Trevorrow did not deny that the film could involve "dinosaur soldiers",[57] and said the series is "not always gonna be about a Jurassic Park," saying he felt that future films could explore the idea of dinosaurs and humans co-existing together.[52] That same month, Trevorrow hinted that the next film may not involve the Jurassic World theme park,[58] and said he would be interested in seeing a Jurassic Park film made by one of several Spanish horror film directors, whose names he did not mention.[59] Director Juan Antonio Bayona was considered for the job, but was already signed on to direct the World War Z sequel.[60] Pratt and Simpkins confirmed in June 2015 that they are signed on for future films.[61][62]
On July 23, 2015, Universal announced that a fifth film is scheduled for a June 22, 2018 release date. It was also announced that Trevorrow and Connolly will write the script; that the film will be produced by Frank Marshall; that Spielberg and Trevorrow will act as executive producers; and that Chris Pratt and Bryce Dallas Howard will reprise their roles from the previous film.[63] The next day, Trevorrow said the series "isn't always going to be limited to theme parks," and confirmed that the film would not involve "a bunch of dinosaurs chasing people on an island. That'll get old real fast."[64]
