Trivia, insights & behind the scenes
Douglas Trumbull invented the Showscan process (70mm at 60fps) for this film, but studios balked at the cost — so he shot standard 35mm and the hyper-real 'experience' footage was achieved through optical effects and editing tricks.
Natalie Wood died during a production break in November 1981; the studio nearly scrapped the film, but Trumbull fought to complete it using Wood's sister as a body double and rewriting around her absence. The resulting film became a ghost story in more ways than one.
