This is a 60 min film from 1932 by Tom Browning. it was originally banned when it came out, as real 'freaks' were hired and the film boards deemed it too grotesque for public consumption.
Weirdly, American Horror Story, an American show i have loved and watched since its first season, recently did a freak show themed series, set in the fifties, about one of the last remaining freak shows in America. and in this version, a lot of the characters were either heavily influenced or carbon copies of those you see in the original Freaks film.
