Ring up another cast member for the second season of "American Horror Story."
"Breaking Bad" actor Mark Margolis has signed on for the second season of Ryan Murphy's uber-creepy FX drama "American Horror Story."
While Margolis' name might not ring a bell, his "Breaking Bad" character certainly will -- he played wheelchair-bound drug kingpin Tio, who put an end to Gus Fring with an explosive act of self-sacrifice at the end of Season 4.
In keeping with the castings for "American Horror Story"'s second season -- which has been dubbed "American Horror Story: Asylum" -- so far, character details are being kept tightly under wraps. However, Margolis will play a character named Sam Goodwin, an FX spokesman confirmed to TheWrap.
Margolis joins a cast that includes returning members such as Jessica Lange (who took home an Emmy last Sunday for her work in the first season) and Evan Peters, as well as new faces such as actor James Cromwell, Chloe Sevigny and Maroon 5 frontman/"The Voice" coach Adam Levine.
This season, which premieres Oct. 17, takes place in a mental institution on the East Coast.
