Elon Musk is reportedly “freaking out” over a new documentary by documentarian and investigative journalist Alex Gibney.

And by all accounts, there might be a good reason for why Musk is lashing out at Gibney, calling his work a “hit piece” and “boring af.”

The four-hour documentary, which had its world premiere today at the Venice Film Festival earlier this week, featured interviews with Musk’s first wife, Justine Musk, who has had five of his (known) 14 children.

As Agence France Presse reports after attending the premiere, an emotional Justine Musk recalled the billionaire mistakenly claim that he was holding their first child Nevada when he died due to sudden infant death syndrome, when it was actually her.

“I learned the term gaslighting through my relationship with Elon,” she said in the documentary.

She also claimed that Musk refers to the mothers of his many children as “breeders” who “are interchangeable,” a vile descriptor perfectly highlighting the entrepreneur’s deep-rooted misogyny and bizarre obsession with procreation.

Musk has often argued that falling birth rates are humanity’s biggest threat and a major obstacle in his quest to become a multiplanetary species. He has reportedly even gone as far as to offer his sperm to SpaceX employees to seed a Mars colony.

The term “breeder” also highlights his troubled relationship with the at least four known women he has had children with. During the documentary’s premiere this week, Musk’s ex and former conservative influencer Ashley St. Clair, who is featured in the movie, told reporters that she was “offered the opportunity not to speak for $40 million.”

In the documentary, Justine Musk also recalled Musk whispering into her ear that he’s the “alpha in this relationship” — during their first dance at their wedding in January 2000, per AFP.

Her remarks aren’t exactly hard to believe, as we’ve seen plenty of behavior that perfectly aligns with her harrowing comments. Case in point, Musk share a shockingly sexist tweet last year claiming that women were designed to be captured or bartered as property. He has also made revolting tweets in an apparent effort to hit on the singer Taylor Swift.

Musk has also treated his daughter, Vivian Jenna Wilson, with utter disdain and unbelievable cruelty, going on intentionally hurtful anti-trans tirades and pronouncing her “dead.”
