Daniel Radcliffe hit the red carpet in London to promote his new film "Horns," a return to the magic genre that made his name in Harry Potter, though this time with a much darker twist.

The film tells the story of a man who is accused of violently raping and murdering his girlfriend, and awakes to find a pair of horns growing from his head.

SOUNDBITE: Daniel Radcliffe saying (English):

"I think a film like this, as much as it is, in one way, about a guy who grows horns and has to figure out why this is happening and why he is turning into the devil, is actually a film about feeling ostracized and being, feeling like an outsider, and it's about loss and you know, losing the one you love. And those are, despite the sort of crazy sort of surface thing that's going on, those are the themes that hopefully people will be able to relate to."

Despite the fanciful elements of the film, Radcliffe said don't compare it - or him - to Harry Potter.
