Los Angeles: Video streaming giant Netflix is set to release a three-part documentary special on Microsoft co-founder, billionaire, and philanthropist Bill Gates. A new trailer for the three-part docu-series, which is called Inside Bill’s Brain: Decoding Bill Gates, explores the past, present, and future of Gates’ life. The trailer includes commentary on Gates’ ambitious push to being a titan in Silicon Valley, the personal sacrifices he made to ensure that Microsoft could compete with competitors like Apple, and his leap into philanthropy around the world. The documentary series “offers unprecedented access to Gates as he pursues unique solutions to some of the world’s most complex problems with the same level of optimism, curiosity, and fervor that inspired his original vision for Microsoft,” according to a press release from Netflix. It will also answer questions like what Gates’ favorite animal is (dog), what his favorite food is (hamburgers), and what his greatest fear is (that his brain will someday stop working). Helmed by An Inconvenient Truth director Davis Guggenheim, Netflix says this series will premiere on 20 September of this year. "Davis had the idea of making a documentary that looked at the big projects I take on that are risky and might not happen otherwise, and that was interesting to me," Gates told an American news website. "I hope this documentary leaves people optimistic that big problems can be tackled,” he said. From his decades-long run as the head of Microsoft and the controversies involved to his later focus on philanthropy and ending diseases like malaria and polio, his 63 years on earth so far have been the very definition of a wild ride. Gates is a participant in the documentary, sitting down for multiple interviews and allowing Davis’ cameras to follow him around, but it does look as though the film will dig into some of the more unsavory aspects of Gates’ life and personality—namely his reputation for being a very tough, demanding boss. In the trailer, Gates is asked to name his worst fear. "I don't want my brain to stop working," he says.
