Brainstorm (1983 film)

Brainstorm is a 1983 American science fiction film directed by Douglas Trumbull, and starring Christopher Walken, Natalie Wood (in her final film role), Louise Fletcher, and Cliff Robertson.

It follows a research team's efforts to perfect a system that directly records and replays the sensory experiences and emotional feelings of a subject, and the efforts by the company's management to exploit the device for military ends. After a researcher records her own death from a heart attack, her colleagues join forces to retrieve the information and play it back.
