Manhattan is a 1979 American romantic comedy film directed by Woody Allen and produced by Charles H. Joffe. The screenplay was written by Allen and Marshall Brickman. Allen co-stars as a twice-divorced 42-year-old comedy writer who dates a 17-year-old girl (Mariel Hemingway) but falls in love with his best friend (Michael Murphy)'s mistress (Diane Keaton). Meryl Streep and Anne Byrne also star.
The film opens with a montage of images of Manhattan and other parts of New York City accompanied by George Gershwin's Rhapsody in Blue, with Isaac Davis (Woody Allen) narrating drafts of an introduction to a book about a man who loves the city. Isaac is a twice-divorced, 42-year-old television comedy writer who quits his unfulfilling job. He is dating Tracy (Mariel Hemingway), a 17-year-old girl attending the Dalton School. His best friend, college professor Yale Pollack (Michael Murphy), married to Emily (Anne Byrne), is having an affair with Mary Wilkie (Diane Keaton). Mary's ex-husband and former teacher, Jeremiah (Wallace Shawn), also appears, and Isaac's ex-wife Jill Davis (Meryl Streep) is writing a confessional book about their marriage. Jill has also since come out as a lesbian and lives with her partner, Connie (Karen Ludwig).
