The Burt Bacharach score really keeps this quintessential 1960s bedroom farce swinging! Peter Sellers plays Dr. Fritz Fassbender, a psychoanalyst who tries to help Michael James (O’Toole), a notorious womanizer, who desperately wants to be faithful to his fiancée Carole (Schneider). All of the characters wind up checking in to the Chateau Chantelle hotel for the weekend unaware of each other’s presence. We guarantee you that the theme song, written by Bacharach and sung by Tom Jones, will be stuck in your head for days after.
