Magicians are supposed to be entertaining and exciting but in Ryan Murphy's world, they're downright terrifying. FX released the first photo and video of Neil Patrick Harris's guest-starring role on "American Horror Story: Freak Show."

At first he looks like a sweet and innocent "salesman" but he has a dark side. Harris' character is seen performing a magic trick on stage when he slices his subject in half. He also has a weird obsession with Dot and Bette (Sarah Paulson).

According to E! Online, the character is named Chester and he becomes the new owner of Elsa's (Jessica Lange) show. Harris will appear in episodes 11 and 12 and his husband, David Burtka, landed a guest role in the Season 4 finale.

TV Line previously reported that Burtka has a "sexy storyline with Jessica Lange's batty chanteuse." FX previously released episode descriptions for episodes 11 and 12.

Episode 11: "Elsa prepares for her move to Hollywood. The Twins grow enamored with a traveling salesman. Dell plots Jimmy's escape from police custody."

Episode 12: "Dandy gives the Twins troubling information about Chester. Maggie vows to prove her loyalty to Jimmy. The Freaks enforce their harsh code of justice."

"American Horror Story: Freak Show" returns Jan. 7 on FX.
