It has been four years since Robin Williams, a legend not just in comedy, but entertainment as a whole, has sadly left us all when committing suicide in his home. 

Robin’s career in comedy, TV, and movies was so vast that there are undoubtedly multiple generations that primarily know him from his stand-up or Good Will Hunting or Mork and Mindy, etc. In any case, he left an unmistakable mark on pop culture and was a force to be reckoned with on stage and screen. 

Marina Zenovich’s upcoming documentary Robin Williams: Come Inside My Mind will attempt to present the man behind the legend with interviews from the likes of Steve Martin, Billy Crystal, Williams’ family, and more. From what we can tell, you might get a little choked up. 

See a bit of it for yourself in the trailer, then look for Robin Williams: Come Inside My Mind to premiere on HBO on Friday, July 13th.
