Carnal Knowledge (1971)

Continuity mistake: When Sandy takes out a condom in bed with Susan, her hair changes between shots.

Bobbie: I need a life.
Jonathan: Get a job.
Bobbie: I don't want a job. I want you.
Jonathan: I'm taken, by me. Get out of the house, do something useful, Goddammit.

Trivia: The scene in which Sandy takes out a condom while in bed with Susan is the first time a condom was ever shown onscreen.
