Within one week we lost designer Kate Spade and Chef Anthony Bourdain to suicide and are reminded of the 2014 suicide of creative genius Robin Williams. HBO has released the first trailer for a new Robin Williams documentary called ‘Robin Williams: Come Inside My Head’.    The HBO’s documentary will give us a look at his career and life. “You’re only given a little spark of madness and if you lose that, you’re nothing,” the late Williams says in the first trailer for the film that premiered at the Sundance Film Festival. HBO will debut the doc July 16.
