Side Show is a 1931 American pre-Code musical comedy drama film starring Winnie Lightner, Charles Butterworth, Evalyn Knapp and Donald Cook. It was produced and released by Warner Bros. The film was based on a story by William K. Wells. Although it was planned and filmed as a full-scale musical, most of the songs were cut from the film before release due to the public's apathy and aversion towards musicals in 1931.
