Universal Pictures and Steven Spielberg have set a June 13, 2014, release date for “Jurassic Park IV,” with plans to shoot the film in 3D.Spielberg is currently set as a producer with Frank Marshall, and plot details are being kept under wraps as Rick Jaffa and Amanda Silver pen the script. Spielberg recently announced that he would delay production on the sci-fi epic “Robopocalypse,” feeling that the film needed to be rethought. He has not committed to another film, but given that “Jurassic Park IV” is now on the fast track, it’s possible he could step back into the director’s chair. Spielberg was an exec producer on “Jurassic Park III,” which Joe Johnston directed. The third film was thought to mark the end of the franchise, but at the 2011 Comic-Con, where he was tubthumping “The Adventures of Tintin,” Spielberg sparked interest by saying that a fourth “Jurassic Park” was in the works. The “Jurassic Park” trilogy has grossed more than $1.9 billion worldwide, with “Jurassic Park III” grossing $363 million worldwide. Universal is planning to re-release “Jurassic Park” in 3D on April 5.
