Political thriller about an American Korean War vet who suspects that he and his platoon may have been brainwashed during the war, with his highly decorated, heroic friend programmed by commies to be an operational assassin. Loaded with shocks, conspiracy, inventive visual imagery, and bitter political satire of naivete and machinations of the left and right. Excellent performances by an all-star cast, with Lansbury and Gregory particularly frightening. Based on the Richard Condon novel. Featuring a special interview with Sinatra and Frankenheimer in which Sinatra is deified.
