David Koepp Redraws Michael Crichton’s ‘Westworld’ For Warner Bros Film

EXCLUSIVE: After bringing Michael Crichton‘s theme park vision to the screen scripting 1993’s Jurassic Park and two sequels, screenwriter David Koepp is looking to tackle another one. Deadline hears Koepp will revisit Westworld, the 1973 film written and directed by Crichton about an adult fantasy park that allows monied guests with a hankering for the Old West to go up against a coterie of robots wielding six-guns. The vacation turns nightmarish when a crack-shot robot malfunctions and starts drawing down on guests, for real.

The movie starred Yul Brynner, Richard Benjamin and James Brolin. Crichton made the original film for MGM, but this one is for Warner Bros, the studio that used the concept for the TV series by Lisa Joy and Jonah Nolan.

Koepp is writing the script and a major filmmaker is circling.

Watch on Deadline

Koepp, who most recently scripted Jurassic World: Rebirth, hooked back up with original Jurassic Park helmer Steven Spielberg on Disclosure Day, which opens June 12 through Universal and is expected to be one of the blockbusters of this coming summer.

He’s repped by CAA and attorney David Fox.

  Oh FFS. Are you serious?

  You had a recent great show of this, with a great cast, story, and production design just a few years ago and you canned it before it could even be completed. And not only that…you also rapidly pulled it from your own streaming service.

  And now you’re coming back to the well…AGAIN…but just in a new film version? FFS, getta outta here.

    The show was great despite some flaws in the later seasons. I suspect a new feature version will try too hard to be mainstream in the vein of Jurassic Park and everything interesting about the series will be abandoned.

  How about finishing the last version that they canceled with one season left first..

  I’m 90% it’s Steven Spielberg but I hope this isn’t the western he’s been alluding to. He’d do a great job with this – but I’d rather see him tackle an original western that’s straight western. Not “cowboys and aliens” western.

  I’ve had an absolute brainstorm. Bear with me as it’s quite complicated… Why don’t we try some new ideas??? Boom!
