Sweet and Lowdown is a 1999 American comedy-drama mockumentary written and directed by Woody Allen. Loosely based on Federico Fellini's film La Strada, the film tells the story of jazz guitarist Emmet Ray (played by Sean Penn) who falls in love with mute laundress Hattie (Samantha Morton). Like several of Allen's other films (e.g., Zelig), the film is occasionally interrupted by interviews with critics and biographers like Allen, Nat Hentoff, Daniel Okrent, and Douglas McGrath, who comment on the film's plot as if the characters were real-life people.

The film received generally positive reviews upon release, with Penn and Morton receiving Oscar nominations for Best Actor and Best Supporting Actress, respectively.
