Amy Berg’s sexual predator documentary “An Open Secret” has been set for a 20-city U.S. theatrical release beginning June 5, Variety has learned.

The documentary will also be screened for international buyers on May 19 at Cannes in what will be the first public showing of the film since its screening at the New York Doc Fest in November.

“An Open Secret” will hit theaters first in Denver and Seattle before expanding. Vesuvio Entertainment and Rocky Mountain Pictures are handling the release.

Berg, whose credits include “West of Memphis” and “Deliver Us From Evil,” incorporates the testimony of several ex-child performers along with denials from some of their accused abusers. The film centers on the rise and demise of Digital Entertainment Network, an early digital network that’s alleged to have been the center of a Hollywood sex-abuse ring.

The movie features extensive interviews with Michael Egan, who, after participating in the film, drew headlines for a quartet of lawsuits last year against Bryan Singer and three other Hollywood executives that were later withdrawn.

“I am pleased that ‘An Open Secret’ will finally have an opportunity to screen for a larger audience,” Berg said. “It’s an important film about an extremely important issue.”

Producers are Amy Berg and Katelyn Howes. Executive producers are Gabe Hoffman and Matthew Valentinas. Production companies are Esponda Productions, Vesuvio Entertainment, Rocky Mountain Pictures and Berg’s Disarming Films.

“This is clearly one of the most controversial, and most important films of 2015 and sheds light on one of the dirtiest secrets in Hollywood,” said Greg H. Sims, CEO of Vesuvio Entertainment.
