I love lucy: the movie (1953)

The film plays out, with three first-season episodes edited together into a single story: "The Benefit", "Breaking the Lease", and "The Ballet", with new footage included between episodes to help transition the episodes into one coherent storyline. As the series routinely took the format of filming scenes in chronological order, this adds to the "show within a show within a show" format of the film, as viewers watch the cast perform the episodes live. The film itself ends with a "curtain call", as the cast comes out and Arnaz thanks the audience for their support.
