In a two-part BBC documentary, openly gay actor-author Stephen Fry visits with Joseph Nicolosi, founder of the “ex-gay” group NARTH.

In the documentary, titled Stephen Fry: Out There, Fry looks at what it means to be LGBT in 2013 through revealing interviews with openly gay celebrities, such as Sir Elton John, and everyday folks, such as a man who is facing persecution in his native Iran and is seeking asylum in the United Kingdom.

In a segment released on Tuesday, Fry chats with Nicolosi, who claims a 66 percent success rate with converting people from gay to straight.

“Would you say that you have a kind of percentage that you can demonstrate of a success-failure rate?” Fry asks.

“We say a third, a third, a third,” Nicolosi answers. “A third no change. A third significant improvement. A third cured.”

Nicolosi adds that 60 percent of his clients are teenagers. (It should be noted that therapies that attempt to alter a minor's sexual orientation from gay to straight are prohibited in California, where Nicolosi is based. However, groups opposed to the law, including NARTH, have sued to have it tossed out.)

Despite this claimed dramatic success rate, Nicolosi refuses to provide Fry with a former client to interview.

Near the end of the interview, Fry states he's interested in the metrosexual phenomenon.

“I'd say you fit that rather well. You're well groomed, you could easily pass as a gay man,” Fry says with a smile. (The video is embedded on this page. Visit our video library for more videos.)
