Mark Margolis has been working steadily as a character actor for decades. However, the actor tends to disappear into his roles, which is why you may not have realized that he has been in nearly every single movie that Darren Aronofsky has ever made. Of the auteur's seven feature films, Margolis has appeared in all but the most recent effort from the writer-director: "mother!" 

Outside of Aronofsky's work, "Breaking Bad" and "Better Call Saul" fans will no doubt recognize Margolis as Hector Salamanca. A character who has made much of his impact by simply reacting with intense facial expressions and ringing a bell, Margolis' subtle acting abilities are undoubtedly a significant factor in the antagonist's success and popularity.

Though Margolis has over 160 acting credits, there are several other notable films that viewers might recognize him from. The actor has appeared in "Scarface," "Gone Baby Gone," "Hannibal, " and "End of Days," just to name a few. Meanwhile, the performer has also appeared on seminal TV shows like "Law & Order," "Oz," and "Sex and the City."
