Manhattan is a 1979 romantic comedy film. It stars Woody Allen, Diane Keaton, Michael Murphy , Mariel Hemingway, Meryl Streep and Anne Byrne .

The movie was written by Allen and Marshall Brickman , and directed by Allen. Allen insisted that this movie be shown in its proper aspect ratio when it was released on video. As a result, all copies of the movie on video are letterboxed, the first video to be released in such a format. The film is shot in black and white by cinematographer Gordon Willis , who also filmed the The Godfather and its sequels. The music is by George Gershwin.

It was nominated for Academy Awards for Best Actress in a Supporting Role (Mariel Hemingway) and Best Writing, Screenplay Written Directly for the Screen. The film is consistently on the Internet Movie Database's list of top 250 films and was #46 on American Film Institute's 100 Years, 100 Laughs. In 2001 the United States Library of Congress deemed the film "culturally significant" and selected it for preservation in the National Film Registry.

Auteurist film critic Andrew Sarris notably praised Manhattan as "the only truly great American movie of the 1970s."
