Don't Knock the Rock is a 1956 American musical film starring Alan Dale and Alan Freed. Directed by Fred F. Sears, the film also features performances by Bill Haley & His Comets, Little Richard, The Treniers, and Dave Appell and the Applejacks. The title of the film comes from one of Haley's hit singles of 1956. The Haley recording is played over the opening credits, but it is Alan Dale who performs the number in the film. Indeed, while Haley and his band are the top-billed performers in the movie, the story in fact focuses on Dale's character.
