Bob & Carol & Ted & Alice (1969)

Documentary-filmmaker Bob Sanders and his wife Carol attend a group-therapy session that serves as the backdrop for the film's opening scenes. Returning to their Los Angeles home, the newly "enlightened" couple chastise their closest friends, Ted and Alice, for not coming to grips with their true feelings. Bob insists that everyone "feel" rather than intellectualize their emotions, and Carol pronounces "that's beautiful" after anyone says anything even remotely personal. Ted and Alice humor their friends, but a good-natured sexual tension is obviously at work among the foursome.
