Oscar-winning filmmaker Alex Gibney is going to make a documentary about Elon Musk. “I have been working on this film, off and on, for some time and am hugely excited about it,” Gibney said. “I am delighted by this extraordinary group who are working with me. Onward!” Gibney has made a career out of hard-hitting documentaries that include Taxi to the Dark Side — for which he won an Oscar — Enron: The Smartest Guys in the Room, Going Clear: Scientology and the Prison of Belief and Steve Jobs: Man in the Machine.
