U.S. cable network HBO has set an August premiere date for critically acclaimed doc Back on Board: Greg Louganis.

The 86-minute film, directed by Cheryl Furjanic and produced by Will Sweeney and Furjanic, traces the life and career of diver and four-time Olympic gold medalist Greg Louganis, often credited as one of the first openly gay American athletes, and highlights one of the defining moments of Louganis’ career: hitting his head on a diving board in a dive during the preliminary round of the 1988 Seoul Games, and sustaining a cut that required five stitches, then winning gold only days later. Though initially lauded for his competitive spirit, Louganis was later criticized when he announced that he was HIV-positive, setting off a nationwide discussion over HIV/AIDS and sports.

Having premiered at Washington DC’s AFI Docs festival in June 2014, the film has recently completed a successful festival circuit that included audience award wins at both the Outfest Los Angeles Film Festival and the Connecticut LGBT Film Festival. The film also took home best documentary feature film at the Annapolis Film Festival and best editing at the Salem Film Festival.

Exec produced by David Kaplan and Joan Kaplan, Grey Sample and Diana Holtzberg, Back on Board: Greg Louganis premieres August 4 at 10 p.m. EST/PST on HBO and its platforms including HBO Now, HBO On Demand and HBO Go.

“Greg Louganis is one of the most decorated and celebrated Olympians of any generation, and we are delighted to share his story – both personal and athletic – with the acquisition of this documentary,” said Ken Hershman, president of HBO Sports, in a statement. “Greg allowed the filmmakers unrestricted access to his life story and viewers will benefit from this deeply personal portrait and gain a terrific perspective on his complicated and rewarding life.”
