Johnny Carson: King of Late Night (2012)

Chronological look at the life and career of Johnny Carson (1925-2005), with commentary from an ex-wife and more than 30 fellow comedians, friends, employees, and biographers. The biography defines why Carson was an enduring star (his cool, his timing, his genuine laugh, his breadth of knowledge) and pursues his motivations and inner self (a loner with a drinking problem, a decent Midwesterner whose mother withheld approval, a quiet person who loved to entertain). The key to understanding him, argues the biography, is his love of magic.
