With great humor, and much humility, Cranston chronicles his unlikely rise from a soap opera regular, trying to learn the ropes and the politics of show business on the fly, to a recurring spot as Tim Whatley on Seinfeld, finding himself an indelible part of popular culture. He recalls his run as the well-meaning goofball, Hal, on Malcolm in the Middle, proving to writers and fans that he was willing to do anything, anything, for a laugh, and he gives a bracing account of his challenging run on Broadway as President Lyndon Johnson, pushing himself to the limit as he prepared, physically and mentally, for a tour de force that would win him a Tony, to go along with his four Emmys.

Of course, Cranston dives deep into the grittiest, most fascinating details of his greatest role, explaining how he searched inward for the personal darkness that would help him create one of the most riveting performances ever captured on screen: Walter White, chemistry teacher turned drug kingpin.

Discussing his failures as few men do, describing his work as few actors can, Cranston has much to say about innate talent, its benefits, challenges, and proper maintenance, but ultimately A Life in Parts is about the necessity and transformative power of hard work.
