Side Show is a 1931 American pre-Code musical comedy drama film directed by Roy Del Ruth and starring Winnie Lightner, Charles Butterworth, Evalyn Knapp and Donald Cook.

To add to her troubles, her younger sister Irene (Evalyn Knapp), whom she is having educated to become a lady, visits her during school vacation and wants to stay with the circus.

The film was originally intended to be released in the United States early in 1931, but was shelved due to public apathy towards musicals.

After waiting a number of months for public tastes to change, Warner Bros. reluctantly released the film in September 1931 after removing all but one song, "She Came from a South Sea Isle", sung by Lightner.

[citation needed] Mordaunt Hall, critic for The New York Times, gave the film a generally unfavorable review, writing, "What little there is in the way of entertainment in 'Side Show,' the picture now at the Strand, is delivered by Charles Butterworth, but even this clever comedian is handicapped by the hardy efforts of others to arouse laughter.
