Who Was Hector Salamanca?

Margolis' best-known role came late in his career, with the showy role of aged gangster Hector Salamanca on AMC’s acclaimedBreaking Bad. Although Salamanca was paralyzed by a stroke and able to communicate only with a ringing bell, Margolis (who did not speak Spanish) effectively communicated the elderly gangster’s fury, hatred, and vindictiveness solely through his facial expressions, earning him a Best Guest Actor Emmy nomination. Margolis based the performance on his late mother-in-law, who was similarly affected by a stroke. Although Salamanca died in the show’sfourth-season finale, assisting in the explosive assassination of rival drug lord Gus Fring (Giancarlo Esposito), Margolis returned to the role in the prequel seriesBetter Call Saul, depicting Salamanca as a younger man, both before and after his stroke.

With such a prominent role under his belt, Margolis became a sought-after TV guest star, making appearances onThe Blacklist,American Horror Story,Gotham, andConstantine, where he played legendary DC supervillain, Felix Faust. Recently, he reunited with hisBreaking Badco-starBryan Cranston, playing a recurring role onYour Honor.

Margolis is survived by his wife,Jacqueline Margolis, who he married in 1962; their son,Morgan Margolis; his brotherJerome Margolis; and three grandchildren. May his memory be a blessing.
