　　Jurassic World 2 is directed by JA Bayona (Orphan), who takes over for the first movie's director, Colin Trevorrow; he is directing 2019's Star Wars: Episode IX.

　　The Jurassic World sequel also brings back Chris Pratt. Last week, it was reported that veteran actor James Cromwell (24, Babe) was cast. Before that, we learned that Toby Jones (Harry Potter and the Chamber of Secrets) and Rafe Spall (Prometheus) joined the sequel.

　　Little is known about the plot. Trevorrow, who is producing the sequel, said last year that the movie aims to be "more suspenseful and scary." In an earlier interview, he said it may go in something of a new direction.

　　"The audience has given us permission to a certain extent to take this to the next level, and I don't necessarily mean in scale," he said. "I feel very strongly that it's not about more dinosaurs or bigger and better dinosaurs, it's about using this as a starting point for a much larger story about our relationship with these animals.

　　"Jurassic World was very much made with the fans in mind, and I'm not going to forget it, but now we've seen a lot of 'dinosaurs chasing people around on an island' movies. I think you guys and also the general audience is going to be down to explore where else we can go."

　　Jurassic World 2 opens on June 22, 2018.

　　Jurassic World currently stands as the fourth biggest movie of all time, bringing in $1.6 billion at the global box office. It was the first new entry in the series since 2001's Jurassic Park III. The franchise is based on Michael Crichton's 1990 novel.
