"Musk," a long and harsh documentary about Elon Musk, is now in theaters.

Bleecker Street opened the film by Oscar-winning director Alex Gibney in four theaters in New York and Los Angeles, Deadline reported. It runs 225 minutes, plus a 10-minute intermission, which limits how often it can be shown. It expands to about 300 screens next week.

The film premiered at the Venice Film Festival in September and has strong reviews. Deadline said it held a 100% score on Rotten Tomatoes from 28 reviews.

Gibney asks one central question. "How has Elon Musk assumed so much power," he says in the film's narration. "And why did we give it to him?" TheWrap's review called the film "punishing" and "the stuff of nightmares."

Musk did not take part. He has criticized the film on X, Deadline said. Gibney uses a digital Musk avatar that speaks only words Musk has said in public. AI was used to match the voice to the animation, not to create the animation, TheWrap reported.

The film has nearly 20 chapters. It follows Musk from his early companies Zip2 and PayPal to Tesla, SpaceX and X. It includes interviews with Justine Musk, his ex-wife, and Ashley St. Clair, who shares a child with him. The second half focuses on the years since 2020, including his role in the Trump administration's DOGE cost-cutting effort.

Weekend question-and-answer screenings with Gibney sold out in New York, Deadline reported. Guests include producer Ronan Farrow, journalist Zoe Schiffer and St. Clair.

The film arrives the same weekend as Aaron Sorkin's Facebook drama "The Social Reckoning," part of a wave of films about big tech.
