Clocking in at three hours and 52 minutes, the runtime for Musk—an unvarnished documentary about the world’s richest man and how he became the first to claim the title of trillionaire—has enough material to go on for hours longer. The director Alex Gibney, known as the film industry’s Bob Woodward, has covered abuses of power extensively, from Elizabeth Holmes’s fraudulent company Theranos to the inner workings of Scientology. With Musk, he takes on his most enigmatic subject yet. Gibney first charted Musk’s ascent through Silicon Valley with a two-hour cut. But the South African CEO’s foray into politics brought the director back to the drawing board. “What are his goals, what are his actual motivations,” the documentary asks. “Do we even know this man at all?” Gibney’s film looks at the domino effect of alleged scandals, from forced NDAs, to ex-girlfriends, to Musk’s government coup with DOGE. And yet the power Musk has over masses of people is far from waning. “It’s not the end of the path, but it’s definitely a distillation of the journey,” Gibney says of his account. —Maggie Turner
