Child Bride (1938)

Schoolteacher in a rural community campaigns to stop the practice of older men marrying young, underage girls. The film is very controversial both for its theme and for showing twelve-year-old actress Shirley Mills nude during an infamous skinny dipping scene. Although it was banned in many areas, the movie's controversial nature gave it a certain infamy and it played on the so-called exploitation circuit for many years. (imdb, Wikipedia)
