David Koepp is returning to the world of twisted amusement parks. The screenwriter, best known for adapting the hit novel “Jurassic Park” for the big screen, has been hired to pen a reboot of the 1973 sci-fi Western “Westworld.”

Warner Bros. is developing the reboot, which does not have a director attached. The company is in the process of being sold to Paramount Skydance, which could interrupt the studio’s development slate.
