The Mind Benders is a 1963 British thriller film produced by Michael Relph, directed by Basil Dearden and starring Dirk Bogarde, Mary Ure, John Clements, Michael Bryant and Wendy Craig.

Professor Sharpey (Harold Goldblatt) commits suicide after subjecting himself to sensory deprivation experiments in a secret research laboratory. His former colleague Doctor Longman (Dirk Bogarde) volunteers to undergo the same tests to try and establish what drove Sharpey to kill himself. He hopes to clear Sharpey's name with the police, who favour the theory that Sharpey was a double agent, perhaps allied with Communists, and that his death was the final result of his shame over betraying Great Britain. Longman begins subjecting himself to sessions in a sensory deprivation tank in order to prove that use of the technique can make one unusually susceptible to brainwashing or hypnotic suggestion.
