Alex Gibney’s ‘Musk’ Has a Unique Perspective on Daddy Issues

Key points

• Director Alex Gibney says Elon Musk never agreed to an interview for his documentary, Musk. Instead, the team used Musk's public comments to build a simulated version of him that appears throughout the film.
• Musk's father, Errol Musk, was the only person who agreed to take part immediately. Gibney says others, including Musk's first wife, Justine Musk, needed months of persuasion.
• The film runs nearly four hours, including a 10-minute intermission, and is set for release in cinemas on a Friday.
