Johnny Be Good is a 1988 American comedy film directed by Bud S. Smith, starring Anthony Michael Hall as the main character, Johnny Walker. The film also features Robert Downey Jr., Paul Gleason, Steve James, Jennifer Tilly and Uma Thurman. Former Chicago Bears quarterback Jim McMahon and sportscaster Howard Cosell make cameo appearances. Despite starring famous actors and comedians, the film was both a critical and financial failure, grossing $18 million.

Judas Priest, Saga and Ted Nugent, among others, contributed to the soundtrack. The title track, "Johnny B. Goode", originally recorded by Chuck Berry, was re-recorded by Judas Priest for their album, Ram It Down.
