When news broke that Robin Williams had committed suicide in 2014, the world was shocked. How could a man that brought laughter into the lives of so many be depressed to the point of taking his own life? Given his fame and the global response to his passing, it was inevitable that someone would take a deeper look into his life and director Marina Zenovich (Roman Polanski: Wanted and Desired) and HBO Films have done just that. The documentary follows Williams from his childhood to his early comedy career to his dramatic roles later in life and features several interviews with loved ones as well as footage from many of his performances.

The excerpts from Williams’ career prove one thing: he was a comedic genius. Each of his colleagues talks about how electric his energy was and the clips show how he could extemporize and create new jokes at any moment. It’s a never-ending joy to watch him perform and a delight to see how hilarious he can be even off the stage and when not on camera. A great moment shows him heckling the crew for an interview for telling him that his hair is slightly tussled and exemplifies how quickly he could turn the slightest comment into a laugh out loud moment with seemingly no effort. The documentary does a solid job of showing his rise to fame and the performances that led to each step in his career.

Through the film’s many interviews, we get a better sense of who his closest friends were. The most touching of these are with his eldest son, Zak, and Billy Crystal. His son provides a glimpse into how Williams was around his family and the effect that needing to entertain the public had on his private relationships. Billy Crystal, to my surprise, appears to have been Williams’ best friend and had a long, loving friendship with him. Crystal, along with some very personal voicemails left by Williams, explore some of the isolation that Williams felt. The candid nature of both interviews and clear affections each individual had for Williams can at times make the film almost hard to watch. Both are still very much in pain as they talk about Williams, but their confessions provide the deepest insight into the comedian’s life.

The major failing of the film is that despite its overlong runtime it doesn’t explore much of Williams’ psyche. We can infer some of the pain he must have faced before his tragic passing and there is evidence that he had been dealing with depression his entire life, but we’re left wanting for a better understanding of his state of mind. What pain was he dealing with? Why did he feel so alone when there were clearly many that loved him? Films about comedians, whether fiction or documentaries, often reiterate that being a comedian can be excruciating with several secretly being depressed. With Williams’ potentially falling into this category, providing more detail into his thoughts would have helped explain this unfortunate trend. As it is, Come Inside My Mind, offers sufficient information about Williams’ rise to the upper echelons of comedy and plenty of hilarious clips but, ironically, doesn’t include the desired depth into his thoughts.

3/5 stars.
