In A LIFE IN PARTS, Bryan Cranston traces his zigzag journey from his chaotic childhood to his dramatic epiphany, and beyond, to mega-stardom and a cult-like following. He accomplishes this by vividly revisiting the many parts he’s played, on camera (astronaut, dentist, detective, candy bar spokesperson, President of the United States, etc.) and off (paperboy, farmhand, security guard, dating consultant, murder suspect, dock loader, son, brother, lover, husband, father). With great humor and much humility, Cranston chronicles his unlikely rise from a soap opera regular to a recurring spot on “Seinfeld,” and gives a bracing account of his challenging run on Broadway as President Lyndon Johnson.
