American Horror Story: Freak Show's first full-length trailer channels 1932's Freaks, a Pre-Code horror film that employed physically deformed circus stars. Both that film and previous seasons of American Horror Story share a central theme: Don't let appearances fool you; it's often "normal" people who are the real monsters.
In Freak Show, Kathy Bates plays a woman with one beard, Sarah Paulson plays a woman with two heads and Angela Bassett plays a woman with three breasts. Michael Chiklis plays a strong man, which isn't nearly as interesting, but men have never been the interesting part of American Horror Story. Jessica Lange will be the ringleader of this motley crew. How she will top this scene from Season 2, we shall see.
For those who haven't seen Freaks, this is its most famous scene, parodied in everything from The Simpsons to South Park.
