If given the chance, would you want to live forever? For tech millionaire Bryan Johnson, the question isn’t rhetorical. It’s a scientific experiment he conducts on a daily basis — with himself as the test subject. 

From director Chris Smith (Tiger King, Fyre), Don’t Die: The Man Who Wants to Live Forever goes behind the headlines surrounding Johnson’s antiaging crusade. It dives deep into his psyche, revealing the drastic shifts that took the entrepreneur from his own personal struggles to dedicating his time and energy — and a considerable amount of his fortune — to living long beyond even the most ambitious human life expectancy.

The documentary goes beyond the headlines to delve into Johnson’s personal history and motivations, but Smith clarifies that the goal is not to prove Johnson’s detractors wrong. “The goal is never to try to change minds,” he says of his approach to creating documentaries. “It’s trying to put information out there in a way that people can make their own decisions and try to reflect things as accurately as we can.”
