HBO has released the trailer for Robin Williams: Come Inside My Mind, its funny, intimate and heartbreaking portrait of one of the world’s most beloved and inventive comedians.

The documentary underscores what made Williams so unique, ranging from his youthful days in the San Francisco Bay area, to his time in New York at The Juilliard School, to his rocket-propelled fame on TV’s Mork & Mindy, to his profound impact on the American cultural landscape. Mixing interviews with friends and family with clips of his most famous routines, the film captures the spark that made him stand out across four decades in entertainment. Williams’ tragic death in 2014, which revealed he had been suffering from the disease Lewy Body Dementia, left fans around the world heartbroken.

Be sure to tune in to HBO July 16 at 8 p.m. ET for the film's premiere.
