This spoof of documentary films stars Woody Allen as Leonard Zelig, the famous "Chameleon Man" of the 1920's, whose personality was so vague he would assume the characteristics of whomever he came into contact with. Filmed in black-and-white, the movie simulates the look of a newsreel, complete with stentorian narration.
Zelig is the ultimate camp follower, a celebrity nonentity who fits in everywhere because he actually changes his personality to blend in with his surroundings.
