Actor Denis O'Hare confirmed that he will be back on the fourth season of "American Horror Story".

In his Twitter account, the actor posted a photo of the set goods and a script. The caption reads, "First day of shooting on AHS Freakshow. What a nice way to be welcomed. #HelloNOLA."

Denis O'Hare joined the previous season of "American Horror Story" Coven. According to SpoilerTV, Denis O'Hare will appear in the Halloween episode of the series and play the character named Edward Mondrake. The character is reported to be an Englishman who lived around the 19th century. His character will have two faces. This condition is due to a congenital disease named "Diprosopus."

Based on the previous work of Denis O'Hare, it is most likely that the fourth season of "American Horror Story" will be freaky. This sparked various speculations about his character. Some reports said that Edward's second face will be his "evil twin" who whispers to him.

Other outrageous stories claimed that Edward's twin will be a girl, which is quite impossible since parasitic worms are of the same sex. His twin will make him suffer as the former will keep him awake because of the hateful whispers it mumbles at night. Moreover, Edward Mondrake will be a "tormentor" of Kathy Bates' character in the past.

The casting sheet of the show allegedly leaked during Comic Con where it confirmed that the cast will be consisted of Sarah Paulson as the conjoined twins Dot and Bette, Kathy Bates as Effil Darling; Evan Peters as Jimmy Darling; Emma Roberts as Maggie; Angela Bassett as Desiree Dupree; Michael Chiklis as Wendell Del Toledoand Jessica Lange as Elsa Mars, as the ring master of the freak show.

"American Horror Story" season 4 entitled Freak Show will go on air on October 8 on FX.
