Since the release of the third Jurassic Park film in 2001, progress on a potential fourth film endured what has been termed "development hell" for more than a decade. In early 2013, Universal Pictures announced a release date and director for Jurassic Park 4. Trevorrow said the film will take place 22 years after the events of the first film. On September 10, 2013, Universal Pictures confirmed it will release the film, retitled Jurassic World, on June 12, 2015.
