High school can be a scary place, but Glee creator Ryan Murphy is venturing into some truly terrifying territory for his new show American Horror Story. Featuring Tony winner Denis O'Hare (who's no stranger to supernatural series thanks to his days as a murderous vampire king on True Blood), Tony nominee Lily Rabe (Broadway-bound again this fall in Seminar) and Broadway veteran Jessica Lange, American Horror Story follows a couple (Connie Britton and Dylan McDermott) as they move into a haunted house in Los Angeles. Take a look at the spooky trailer below, then get ready to tune in when the show begins its run on F/X on October 5.
