As scary as it may seem, Bryan Cranston was deeply informed by personal experience in how he approached Walter White, the character he played on the hit television program "Breaking Bad." In what may be the 'crazy ex-' story to beat all 'crazy ex-' stories, Cranston explains how a series of dark encounters with a mercurial girlfriend helped him tap into Walter White's most menacing qualities. But Cranston is interested in more than the fictional roles he's given to play as an actor. He finds the roles that each of us play in life—from partner, to friend, to citizen, and so on—are what really defines who we are, what we do, and the shape our lives take over their long arc. His book on the subject is aptly called A Life in Parts.
