'American Horror Story' Season 2 adds 'Breaking Bad' villain, plus go behind the scenes in new video

"American Horror Story" is welcoming a lot of new faces to the Asylum in Season 2. The latest is Mark Margolis, who played the wheelchair-bound drug czar Hector Salamanca on AMC's "Breaking Bad," reports EW.

Margolis received a Guest Actor Emmy nomination for his "Breaking Bad" work. So far the only detail about his "AHS" role is the name -- Sam Goodwin.

"AHS" has also added Amy Farrington ("Hung") as a worried mother and David Chisum ("One Life to Live") as a loving husband -- though we don't know if they are a married pair or not.

Finally, check out the video below for a behind-the-scenes look at the filming of "AHS" Season 2, which returns Wednesday, Oct. 17 on FX.
