Has Harry Potter gone to the dark side?

Not quite. But Daniel Radcliffe certainly looks like he has in the trailer for his new movie, “Horns.”

In the film, based on the 2010 novel of the same name, Radcliffe plays a man whose girlfriend has just been raped and murdered, and he’s everyone’s prime suspect. One morning he wakes up to find he has grown a pair of horns and developed strange new powers.

Wand play this isn’t.

There’s no US release date yet, but “Horns” opens in UK theaters on Halloween.
