In God Loves Uganda, Academy Award-winning filmmaker Roger Ross Williams takes a close look at the forces behind Uganda's anti-gay movement, some of which can be traced back to America.

The documentary premiered at the Sundance Film Festival in January. Now, the film is starting to roll into theaters: New York last Friday and Los Angeles on Friday, October 18.

In 2009, Ugandan lawmakers introduced a bill that proposed the death penalty for people who engage in gay sex. The Anti-Homosexuality Bill, which has yet to become law, has attracted worldwide condemnation and protests.

In the film, Williams explores the role of the American Evangelical movement in fueling Uganda's anti-gay law.

“American evangelicals have done a lot of great work,” Willams told NRP's All Things Considered. “But it's a certain type of fundamentalist evangelical ideology that came in there and basically instilled in a lot of the young people in Uganda this message that biblical law is above any other law.”

Williams said that evangelical leaders in America are increasingly looking abroad to pitch their message.

“Everyone I've talked to in my film has said, 'You know, look: America's lost.' As marriage equality has passed, America is lost to them, but they are winning the war in Uganda,” Williams said.
