Inside Bill's Brain: Decoding Bill Gates is a new three-part documentary that premieres on September 20. It's directed by Davis Guggenheim who produced An Inconvenient Truth and directed Waiting for Superman.
"When I thought about topics to cover, I knew I didn't want to make a promotional piece about his work," Guggenheim said. "Instead, I opted to focus on the tougher, more complex problems that nobody wants to think about, like sanitation and nuclear energy. Bill chose to take these issues on, even knowing that he might fail, and I had an instinct that seeing him wrestle with these intractable and frustrating problems would reveal something interesting about him as a person."
It'll be interesting to see how warts-and-all the documentary really is (or isn't).
