Mark Margolis

Mark Margolis's best-known role came late in his career: Hector Salamanca, the wheelchair-bound cartel patriarch whose bell-ringing became one of Breaking Bad and Better Call Saul's most menacing running images, earning him an Emmy nomination. He appeared in all six of Darren Aronofsky's first films, starting with Pi, and had a long supporting career that included Scarface and Oz.
