Huston will be paying the role of Douglas Greathouse, an influential head of a hospital's obstetrics department. His character could go two ways--either he will assist in Masters' research on sex or dissaprove of it. No other details about the nature of his role have been given away yet.

Huston most recently played the Axeman, a serial killer, in American Horror Story: Coven. He is the latest addition to a bunch of stars that have been cast for season 2 of Masters of Sex. Most recently Breaking Bad's Betsy Brandt joined the show as William Masters' new secretary.

Keke Palmer will also be joining as Coral, nanny to the Masters' baby. The 20-year-old actress has featured in films like Animal and Ice Age: Continental Drift before. Audiences will also see her in the upcoming film, A Trip to Bountiful.

In February, Allison Janney confirmed that she would be continuing her role as Margaret Scully in the second season to Digital Spy. Scully is in a sexless marriage with Provost Barton Scully, who is revealed as being homosexual in the second half of the first season.
