Russell Brand Talks Revisiting Addiction In 'Get Him To The Greek'

'It's not worth it,' he tells MTV News of using drugs and alcohol again. 'Not for me.'

Russell Brand is bound to bring the laughs when he reprises his role as rock star Aldous Snow in "Get Him to the Greek," but there's one major disparity between the comedian and his character: While Snow regularly indulges in promiscuous sex and drug-abusing behavior, Brand has kept his distance from that kind of lifestyle since abandoning drugs and alcohol several years ago.

Still, Brand's experience as an addict proved helpful in crafting the character of Snow, as the actor told MTV News that it provided some authenticity to his performance in "Get Him to the Greek."

"Say that when you were a child, there was a time where someone stood in front of you and strangled a kitten, then you had to do a film in which there's a scene where somebody strangles a kitten. You'd definitely remember the childhood time when that kitten-strangling happened, which would make you more authentic in the film," he explained. "But when you go home, you'll say, 'Oh, that poor kitten.' [Playing Snow] was a bit like that, except there were no kittens strangled in the making of this film. Well, there was one."

Brand said that his character's closeness to drug culture never tempted the actor himself into relapsing: "I don't take relapsing very seriously as a possibility in terms of thinking of it as 'Must not relapse. Must not relapse.' But it reminded me, 'Don't do drugs.' It's not worth it. Not for me."

That's not to say Brand isn't without his vices, of course.

"Every day, nine times, I watch 'Finding Nemo,' " he laughed. "Is that a problem? I love that little guy. He's got that tiny fin! It makes me happy."
