Elon Musk has spoken out about Alex Gibney‘s four-hour documentary on him, which premiered at the Venice Film Festival on Tuesday, calling it a “hit piece” that is “boring.”

“Musk,” which earned a four-minute standing ovation at its premiere and a slew of positive reviews, seeks to make sense of the world’s richest man and the outsized influence he has on the world. It dives deep into Musk’s shift to MAGA supporter, controversies surrounding his Occupy Mars mission and Tesla’s self-driving cars and his contentious relationships with several of the mothers of his 14 children.

Musk began replying to posts on X about the documentary on Wednesday, writing under a video of Gibney at the movie’s press conference that “dogshit is worth more respect” than the Oscar-winning documentarian. He claimed in a separate reply that Gibney had “just assembled a hit list of people who either have an axe to grind or don’t even know me (but still have an axe to grind),” adding: “He has ZERO integrity. Horrible human.” It is unclear if Musk has seen the documentary.

“Musk” features interviews with the tech billionaire’s first wife, Justine Musk; his father, Errol Musk; Ashley St. Clair, the mother of his 13th child; Geoffrey Hinton, the “godfather of AI”; Tesla co-founder Martin Eberhard; LinkedIn co-founder Reid Hoffman and more. St. Clair appeared on the press conference panel at Venice and alleged that she had been offered a $40 million NDA by Musk after the birth of their child, Romulus, last year. “I want to set the example for my kids that we should never take being materially comfortable that we’re speaking the truth,” St. Clair said.
