A little over a month after its award-winning debut at the 2014 Sundance Film Festival, HBO has just announced a theatrical release for its hit documentary The Case Against 8.

The Case Against 8 will be released in theaters in New York and Los Angeles on June 6, with an expansion planned for select cities on June 13. The film will also premiere on HBO, coinciding with the first anniversary of the landmark Supreme Court ruling on marriage equality.

Directed by Ben Cotner and Ryan White, the film, which has been five years in the making, chronicles the groundbreaking Supreme Court case that overturned Proposition 8, California’s ban on same-sex marriage.

“We feel it’s important to bring the story of the men and women behind this roller-coaster battle to screens across the country, and we’re extremely proud to bring attention to a fundamental civil rights issue that faces the country today,” said Sheila Nevins, president, HBO Documentary Films in the announcement.
