New York Times reporter Dave Itzkoff talks with Recode's Peter Kafka about his new book, "Robin: The Definitive Biography of Robin Williams." Itzkoff traces the history of the manic comedian and actor, whose stardom spanned more than four decades in roles in TV shows, such as "Mork and Mindy," and movies, like "Good Will Hunting." After Williams' death by suicide in 2014, Itzkoff says fans and the media were led astray by incorrect or incomplete explanations for what happened, and that Williams' reasons for taking his own life were more complicated than many assumed. Itzkoff also talks about whether another movie star like Williams could emerge in today's Hollywood, his interactions with the comedian as a journalist and how much time he spends crafting jokes for his popular Twitter account @ditzkoff.
