Director Reed Cowan's documentary on the Mormon Church's decades-old involvement in the fight to ban gay marriage in the United States will open in limited markets June 18.

8: The Mormon Proposition premiered in January at the Sundance Film Festival in Park City, Utah, just 30 miles from the world headquarters of the Church of Jesus Christ of Latter-day Saints.

The film is the first for newly-formed independent film distributor Red Flag Releasing, which is headed by Paul Federbush and Laura Kim, two film industry veterans. The pair hope to distribute as many as four independent features per year.

Proposition focuses on California's 2008 fight over Proposition 8, the ballot measure that outlawed gay marriage in the state.

“This film is for those who've suffered from religious bigotry,” Cowan, who is openly gay, said in a statement. “Its sold-out screenings at Sundance and in Salt Lake City are the first step for people to learn the truth about such a damaging and divisive effort.”

The film is narrated by Milk scribe Dustin Lance Black.

Proposition will open in 14 markets on June 18, including New York, Los Angeles and Salt Lake City, and in San Francisco, Berkeley and Santa Rosa on June 25.

A Wolfe DVD release of the film is scheduled for July.

“This is a vitally important documentary for the gay community,” Maria Lynn, president of Wolfe, said in a statement. “The message is urgent and we believe it will spur those who watch it to get politically involved.”
