Zelig is a 1983 American mockumentary written and directed by Woody Allen, and starring Allen and Mia Farrow. Allen plays Leonard Zelig, a nondescript enigma who, out of his desire to fit in and be liked, takes on the characteristics of strong personalities around him. The film, presented as a documentary, recounts Zelig's intense period of celebrity in the 1920s and includes analysis from present day intellectuals.
The film was photographed and narrated in the style of 1920s black-and-white newsreels, which are interwoven with archival footage from the era and re-enactments of real historical events. Color segments from the present day interview real and fictional personages, including Saul Bellow and Susan Sontag.
