Warner Bros. is developing a reboot of the 1973 sci-fi Western film “Westworld,” with screenwriter David Koepp attached to write the script, according to multiple reports. Koepp, who is known for adapting Michael Crichton’s novel “Jurassic Park” for the screen, is returning to the type of genre material associated with high-concept science fiction. The reboot is in development at Warner Bros., but the project does not currently list a director. No further details about casting, production timeline, or the creative direction of the reboot are provided in the available reports. The announcements focus on Koepp’s involvement and the studio’s decision to pursue a feature-film continuation or reinterpretation of the original “Westworld” concept. The sources do not indicate whether the film will directly remake the 1973 plot or adapt elements from related “Westworld” media. At this stage, the reporting is limited to the key development step: Warner Bros. commissioning Koepp to write a new movie version, with additional roles still to be determined.
