Brainstorm is a 1983 science fiction film directed by Douglas Trumbull and starring Christopher Walken and Natalie Wood (in her last film appearance). Louise Fletcher and Cliff Robertson are also featured in the cast. The film was filmed at various locations in North Carolina, including Chapel Hill, Durham, Kitty Hawk, Raleigh, and Southern Pines. A team of scientists invents "The Hat," a brain/computer interface that allows sensations to be recorded from a person's brain and converted to tape so that others can experience them. The team includes estranged husband and wife Michael and Karen Brace (Walken and Wood), as well as Michael's colleague Lillian Reynolds (Fletcher). At CEO Alex Terson's (Robertston) instruction, the team demonstrates the device to gain financing for more development. One team member, Gordo (Jordan Christopher), has sexual intercourse while wearing the recorder, and shares the tape with other colleagues, including Hal Abramson (Joe Dorsey). Hal splices one section of the tape into a continuous orgasm, which results in sensory overload that nearly kills him - leading to his forced retirement.
