Side Show (1931)

Winnie Lightner, tomboy of the talkies [sic] stars in this comedy-drama as Pat, a traveling carnival troupe member who does everything from high diving to hula dancing, with time left over to romance meek and mild Sidney (Charles Butterworth) and try to save her younger sister, Irene (Evelyn Knapp), from a lecherous carny barker. The slapstick big-top finale is a highlight.
