Imagine a machine that downloads one person’s thoughts and sensations to another individual. Any person. Any experience. Now imagine how that breakthrough technology might be corrupted in the wrong hands. Christopher Walken, Natalie Wood (in her final film) and Louise Fletcher play virtual reality researchers determined to keep their high-tech invention from lowdown tampering in Brainstorm. Bruce Joel Rubin (Ghost, Jacob’s Ladder) provides the tantalizing what if? story, and Douglas Trumbull (inventor of the first simulation theater and a special-effects trailblazer on 2001: A Space Odyssey) produces and directs this dazzling adventure.
