"American Horror Story: Freak Show" has begun filming for season 4, and the characters for its illustrious cast has finally been revealed.

According to Out Magazine, an alleged leaked cast sheet shows that Jessica Lange's character will be Elsa Mars, the German expat running the last freak show in the country. Emma Roberts is reporting for duty as Maggie, and of course, Sarah Paulson will play Siamese twins Bette and Dot. Popular character Pepper from "Asylum" will reprise her role.

Michael Chiklis is Evan del Toreado, the ex-husband of Desiree Dupre, played by Angela Bassett. Del Toreado's son is Jimmy Darling, played by Evan Peters. Evan Peters' mother is Ethel Darling, played by Kathy Bates.

In addition, the cast sheet shows that "American Horror Story: Freak Show" will add a new villain called the Twisted Clown played by John Carroll Lynch. According to executive producer Tim Minear, the Twisted Clown will "scare the shit out of you," and described "Freak Show" as "Douglas Sirk meets Zodiac."

"American Horror Story: Freak Show" will also add Wes Bentley ("The Hunger Games") and Finn Wittrock ("The Normal Heart"). Bentley will play someone who torments Kathy Bates' character.

During the San Diego Comic-Con, Sarah Paulson revealed her thoughts on playing two characters at once.

"Bette is my favorite right now, and it's a week in and I don't know why that is," Paulson said during the panel. "It feels very organic to me and I love her." She clarified that she isn't wearing a prosthetic to play the part and eluded to a mystery in terms of how—and why—the process is done offscreen and storywise."

"It's done in a way that's never been done before in a sense that no person has played a person with two heads … people have done it with another actress [but] this is a new thing."
