Holy Hell, which debuted at last month's Sundance Film Festival and competed for a documentary prize, centres on the Buddha Field community and includes interviews with ex-members, according to Variety.
"Holy Hell is relentless, haunting and unforgettable. This unflinching documentary expose takes us on a beautiful and bizarre journey in search of faith, love and family, but ends up showing us how the business of spirituality, power and corruption are often religion's menage a trois," Leto, 44, said.
"Jared saw an early cut of the film, which I shot over 22 years as the unofficial videographer of the group, and responded to the intimacy of our story," director Will Allen added.
