Bryan Cranston as
Walter White, a high-school chemistry teacher who, shortly after his 50th birthday, is diagnosed with
Stage III lung cancer and turns to making
meth to secure his family's finances. As his shady business progresses, Walter gains a notorious reputation under the alias of "Heisenberg". Cranston stated that, though he enjoyed doing comedy, he decided he •
Anna Gunn as
Skyler White, Walter's wife who was pregnant with their second child before his diagnosis and who becomes increasingly suspicious of her husband after he begins behaving in unfamiliar ways. Gunn sees Skyler as "grounded, tough, smart and driven". Gunn sees Skyler's stalled writing career as her biggest dream, saying, "I think she really deep down yearns to be an artist and to be creative and productive." •
Aaron Paul as
Jesse Pinkman, Walter's cooking partner and former student. Paul sees Jesse as a funny kid. "He's just this lost soul – I don't think he's a bad kid, he just got mixed in the wrong crowd." Paul elaborated on the character's background, saying, "He doesn't come from an abusive, alcoholic background. But maybe he just didn't relate to his father, maybe his father was too strict and too proper for Jesse." Paul compared the character's relationship with Walt to
The Odd Couple. •
Dean Norris as
Hank Schrader, Walter and Skyler's brother-in-law via his marriage to Skyler's sister, Marie. Hank is a
DEA agent. At the beginning of the series, this character was intended to be the "
comic relief". •
Betsy Brandt as
Marie Schrader, Skyler's sister and Hank's kleptomaniac wife. Brandt described Marie as "an unpleasant bitch", but also stated that there was more to her than that. "I think we're seeing more of it now that she would be there for her family. But it's all about her." •
RJ Mitte as
Walter White Jr., Walter and Skyler's son, who has
cerebral palsy. He begins lashing out after Walter's cancer announcement. Mitte himself has cerebral palsy, although his is a milder form. Mitte stated that he had to regress from his therapy to portray the character, staying up late into the night to slur his speech and learning to walk on crutches so that his walking would not look fake. •
Giancarlo Esposito as
Gustavo "Gus" Fring (seasons 3–4; guest season 2), a Chilean high-level drug distributor who has a cover as an owner of the fast-food chain
Los Pollos Hermanos. Esposito stated that for the third season, he incorporated his
yoga training in his performance. •

Jonathan Banks as
Mike Ehrmantraut (seasons 3–5; guest season 2), works for Gus as an all-purpose
cleaner and hitman, and also works for Saul as a private investigator. The character of Mike has been compared to
Harvey Keitel's Winston Wolfe character in
Pulp Fiction, which Banks says he is not trying to emulate: "I immediately tried to put it out of my mind, quite honestly. His cleaner ain't my cleaner. But throughout this world, you would suspect there had been a great many cleaners, whether government-run or individual contractors." •
Laura Fraser as
Lydia Rodarte-Quayle (season 5), a high-ranking employee of Madrigal Electromotive and a former associate of Gus Fring. She reluctantly begins supplying Walt and Jesse with
