The Muppet Movie

The Muppets have gathered in a theatre, in a Hollywood film studio, to screen their new biographical film, The Muppet Movie. In the film-within-a-film, Kermit the Frog enjoys a relaxing afternoon in a Florida swamp, strumming his banjo and singing "The Rainbow Connection", when he is approached by Bernie (Dom DeLuise), a Hollywood talent agent who encourages Kermit to pursue a career in show business. Inspired by the idea of "making millions of people happy", Kermit sets off on a cross-country trip to Los Angeles, but is soon pursued by entrepreneur Doc Hopper (Charles Durning) and his shy assistant Max (Austin Pendleton) in an attempt to convince Kermit to be the new spokesman of Hopper's struggling French-fried frog legs restaurant franchise, to Kermit's horror. As Kermit continuously declines his offers, Hopper resorts to increasingly vicious means of persuasion. Read more on Wikipedia.
