Queerty blog found an interesting interview at gay South African site Mamba with Noah's Arc lead Darryl Stephens and I found it via AfterEtton.com. Stephens claims in the interview that he's through playing gays for a while (he says it's a "moratorium"), and then goes on to explain why he and his cast do not discuss their sexualities publicly:
"The one thing I can say is that the straight actors on this show [Noah’s Arc] are not saying "we’re straight, playing gay". In the same way that the gay actors aren’t saying "we’re gay". No-one [on the show] is talking about their personal lives. We sat down – all the actors sat down – and said that the straight actors are not going to get all the press because they’re being “so brave” in playing gay."
In addition to the title character on "Arc," Stephens plays gay in the current release "Boy Culture" and had a role in the comedy "Not Just Another Gay Movie."
Stephens later notes that he's of course up for a movie version of Arc, adding, "Noah is a great character for me. A lot of people relate to him – he’s a gift. I won’t give up playing this character."
