While 'Once Upon a Time' is already creepy with its fantasy-filled scenes, the people behind the series decided to make things creepier by casting Marilyn Manson.

According to the Rolling Sone, Manson is scheduled to join the cast in November. The rocker will reportedly give life to the haunting voice of The Shadow.

Even if The Shadow first appeared in the end of Season 2, the viewers haven't heard its voice yet. It has always been the plan of the show's creators to include Manson in the show. "We've always been enormous fans of Marilyn Manson. We wanted to cast someone with the vocal ability to make our skin crawl," says Eddy Kitsis and Adam Horowitz.

'Once Upon a Time' Season 3 revolves around a terrifying version of Neverland that is ruled by the evil Peter Pan. The good team is composed of Emma, Regina, Captain Hook, and her parents Snow and Charming.

Will Manson be able to give justice to The Shadow's villainous vocal?
