Looking for Mr. Goodbar began as a novel by Judith Rossner. Rossner based the novel on the events surrounding the brutal murder of Roseann Quinn, a 28-year-old New York City schoolteacher in 1973. Looking for Mr. Goodbar is a 1977 film starring Diane Keaton, Tuesday Weld, and Richard Gere, based on that novel.
The film, starring Diane Keaton as Dunn, traces the sexual awakening of a young teacher searching for excitement outside of her mundane existence. Originally in search of the "perfect man", whom she refers to as "Mr. Goodbar", she begins losing control of her life as her sexual appetite grows. Quiet and reserved teacher by day, sexual deviant and bar-hopper by night, Dunn begins to dabble in drugs and unstable men. Her self-destructive behavior is a means of escaping her numbing existence and testing her boundaries and providing excitement in her otherwise safe and boring life. A true micro meshed image of life in the 70's. The cast includes a very young Richard Gere. Ultimately, her sexual addiction and high risk behavior put her life in danger.
