Brainstorm

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. Plot Scientists invent a brain–computer interface enabling sensations to be recorded from a person's brain and converted to tape for others to experience. The team includes estranged husband and wife Michael and Karen, as well as Michael's colleague Lillian. At CEO Alex's instruction, the team demonstrates the device to investors to gain financing. Karen dons the recorder while working with Michael and Lillian. When Michael plays the tape back, the group realizes that emotional experiences are also recorded. Michael tapes his memories of times with Karen, which he shares with her, leading to their reconciliation.
