Actors who played Munchkins, Bert Lahr's daughter, John Waters, the film's choreographer, film critics, and others tell stories about the making of the "Wizard of Oz," discuss its special effects, and assess its place in film history. Munchkins also talk about Judy Garland, the set, and the rehearsals; Buddy Ebsen describes his short-lived and nearly-fatal time as the Tin Man; and, footage from the film illustrates the points made by talking heads.
