In another new interview with MTV, Daniel Radcliffe talks about his involvement in The Trevor Project; a nonprofit organization offers 24/7 round the clock support for lesbian, gay, bisexual, transgender and questioning youths.

“It’s something I’ve always been quite passionate about. Because I grew up around gay men, it was always a natural thing to me. It was never something I ever gave a second thought to.” He admits growing up, he didn’t understand how some people could be so ignorant. “Some are gay, some are straight — didn’t make any difference to me. When I went to my second school, I heard terms like ‘puff’ and ‘homo’ getting thrown around. It never occurred to me that some people might have a problem with it.

“The Trevor Project is the only nationwide around-the-clock crisis- and suicide-prevention help line [of its kind],” Radcliffe said of the cause. “[It’s designed] for gay, lesbian, bisexual, transgender and questioning youth. There will also soon be a ‘Trevor’ iPhone application.”

Though many stars in Hollywood support causes that they can relate to on a personal level, Radcliffe doesn’t feel that is a necessity. When asked why he chose to support The Trevor Project, his response is: You don’t have to be gay to be a supporter — you just have to be human.

MTV has a new interview with Daniel Radcliffe where he talks about the end of Potter filming.

“It will be very sad when it comes to a finishing,” Daniel Radcliffe said of his rapidly diminishing days working on the final “Potter” film. “But it’s something you have to accept. Yeah, we’ve had a few people finish off their stories in the film, and they’ve been going home,” Radcliffe said of actors like Helena Bonham Carter, who told us recently that she wrapped a few months ago. “It is odd [seeing them leave].

“I did have a moment the other day, in the makeup room that I have been in for 10 years now,” he revealed. “I did walk in and go, ‘Wow, this is [hitting me]. One day — in about four or five months from now — I’m gonna walk in here for the last time.’ Especially since, after we’re done shooting, they’re redoing the entire studio, tearing down and starting again.”

“It’s going to be amazing,” he said of the renovation of the stages that have housed “Potter” for a decade. “A big investment is going into Leavesden [Studios], and England will finally have a third film studio. They’ve always had Shepperton and Pinewood, but to have Leavesden? That will do wonders for the film industry in England, which is always a struggle to keep going.”

“What’s been amazing about Potter is that Potter has been the major film in England for the last 10 years,” explained the star, who also recently used his star power for good while filming a public-service announcement in support of the Trevor Project. “[Our films] have given a lot of people jobs, myself included.” And as for his upcoming second decade in Hollywood, Radcliffe said he won’t spend it looking backward. “It’s also very exciting [to be finishing the series],” he said. “And I’ll hopefully have something to go onto shortly afterwards.”
