Did the CIA help Charles Manson control his family's minds? Errol Morris' “CHAOS: The Manson Murders" attempts to find out.

The movie is credited as an adaptation of Tom O’Neill’s book Chaos: Charles Manson, the CIA, and the Secret History of the Sixties, a sprawling, occasionally off-the-rails investigation that eventually ties Manson to the U.

Errol Morris' new documentary pulls from Tom O'Neill's 2019 book, which disputes much of what we know about the Manson Family.

Errol Morris' film is built around the theory that Charles Manson learned mind-control techniques from the CIA. But guess what? There's no evidence.

Tom O'Neill was commissioned by Hollywood-centric film magazine Premiere to investigate exactly what had - by then - happened a mere 30 years earlier, when a small-time criminal, Charles Manson, was unveiled as the mastermind behind one of the most brutal and defining crimes of the 20th century.
