In his August 2013 Terry Gross interview, Bob Odenkirk said that he based his character Saul Goodman partly on the Hollywood agents Robert Evans and Ari Emmanuel. Emanuel, who was also the inspiration for the character played by Jeremy Piven in the TV series Entourage and a different Odenkirk character, Stevie Grant on The Larry Sanders Show, is Odenkirk’s actual agent.

A main plot point of Breaking Bad concerns the main character, Walt, being a bona fide chemistry genius. Marius Stan, who plays Walt’s impressively-eyebrowed boss at the carwash Bogdan, in real life is an actual chemistry genius. He has a PhD in Chemistry, and still works in that field.
