Now the heartthrob is fighting zombies in the film adaptation of the best-selling book “Warm Bodies,” also starring Nicholas Hoult of “A Single Man.” In his first gay press interview, we picked Dave’s brain on the outsider theme of his new flick, whether he plans to work on a gay project with James and how his sexually explicit videos are in no way baiting the boys who love them. The 27-year-old has attracted a big gay fan base ever since he starred in the 2007 indie “After Sex,” the one where Mila Kunis was a lesbian, and put Channing Tatum in his place after a homophobic mix-up in last year’s “21 Jump Street.” But it’s Dave’s viral Funny or Die videos, where he’s had sex with himself and also told actor Chris “McLovin” Mintz-Plasse “I wanna strip you down” (and other homoerotic things), that have really made the gays smitten. James Franco isn’t the only one fearlessly exploring homosexuality in his career.
