This is the best summary I could come up with:

Mark Margolis, the journeyman actor who turned in a commanding performance as the vindictive drug runner Hector Salamanca, a man of few words and a bell, on Breaking Bad and Better Call Saul, has died.

A protégé of Stella Adler who did double duty as the legendary acting teacher’s personal assistant, Margolis also stood out as the Bolivian henchman Alberto the Shadow in Brian De Palma’s Scarface (1984); as the gravelly voiced landlord Mr. Shickadance looking for the rent in Ace Ventura: Pet Detective (1994); and, from 1998-2003, as the HIV-infected mob boss Antonio Nappa on HBO’s Oz.

The Philadelphia native played an aging math teacher for Darren Aronofsky in Pi (1998), then showed up in the filmmaker’s next five movies: as the guy who keeps selling Mrs. Goldfarb’s (Ellen Burstyn) TV back to her in Requiem for a Dream (2000); as a priest in The Fountain (2006); as Randy “The Ram” Robinson’s (Mickey Rourke) landlord in The Wrestler (2008); as a ballet patron in Black Swan (2010); and as a “fallen angel” in Noah (2014).

In the spectacular season-four finale, “Face Off,” which aired in October 2011, Salamanca gets his revenge on drug kingpin Gus Fring (Giancarlo Esposito) as part of a suicide mission, and he received an Emmy nomination for outstanding guest actor in a drama series in 2012.

In exchange for classes, he served as Adler’s personal assistant for nearly three years, getting her cabs, carrying her groceries back to her apartment opposite the Metropolitan Museum of Art and checking coats for guests when she hosted a party.

He managed a coffee house on MacDougal Street in Greenwich Village — “I used to let Richie Havens sit there all night even though he didn’t have any money because I loved listening to his music,” he said in 2016 — built theatrical artwork installations and took geodesic domes to colleges all around the country.
