It appears that the “Asylum” still has vacancies. Mark Margolis of “Breaking Bad” has been added to the season two cast of “American Horror Story.”

Entertainment Weekly broke the news on Friday that Emmy-nominated Mark Margolis would be joining the “American Horror Story” cast in a recurring role. Although it’s confirmed that Margolis would be appearing on the upcoming new season of the mini-series, his role as character Sam Goodwin is being kept under wraps.

Viewers may recognize Margolis from his role on AMC’s hit series “Breaking Bad.” The actor played drug lord Hector “Tio” Salamanca, a villain who was not only bound to a wheelchair, but also suffered from a stroke.

Judging by Margolis’ previous role, will fans see him as a villain as well in the upcoming second season? Or will the actor find himself as a good guy stuck within the asylum walls?

Season two of “American Horror Story” is taking on a whole new life. While previously set in present day in Los Angeles, the new season will take viewers to an institution for the criminally insane in 1964. Inside the asylum, Sister Jude (Jessica Lange), a nun with a troubled past, “rules with an iron fist.” But Sister Jude is barely considered a threat to the inmates compared to what else lurks within the locked doors. “From Nazis and serial killers, to mutants and aliens, no one is safe inside these walls,” boasts a preview from FX.

The premiere episode will introduce viewers to Briarcliff, the name of the institution.

Welcome to Briarcliff Manor, a notorious insane asylum which is home to the deranged serial killer Bloody Face,” explains a synopsis released by FX. “Lurking in the shadows of this ‘sanctuary of healing’ are terrifying evils that blur the boundaries between reality and insanity.”

Although a completely new storyline, season two of “American Horror Story” will feature some familiar faces. Viewers can expect to see Emmy winner Jessica Lange, Zachary Quinto, Sarah Paulson, Evan Peters, Lily Rabe, Frances Conroy and Eric Stonestreet.

New to the series is “The Voice” judge and Maroon 5 frontman Adam Levine, Jenna Dewan, Clea DuVall, James Cromwell, Franka Potente, Mark Consuelos, Lizzie Brochere, Joseph Fiennes and Chloe Sevigny.

Amy Farrington of “Hung” and “The New Adventures of Old Christine” has also been added to the cast, reports Entertainment Weekly. Farrington will play a “worried mother,” while another season newcomer David Chisum of “One Life to Live” and “Drew Peterson: Untouchable” is set to play a “loving husband.”

Season two of “American Horror Story: Asylum” is set to premiere on FX on Wednesday, Oct. 17.
