While Star Wars fans view the Dark Side as a bad place, Daniel Radcliffe — the title wizard in Harry Potter and the Chamber of Secrets— really digs plumbing the murky depths of his character. "I think everybody has a dark side really," the 13-year-old says. "However much you either like to show it or you're afraid to show it, everybody has it."

Those expecting a light, fluffy movie should beware: Chamber of Secrets — opening Friday — is much darker in tone than Harry Potter and the Sorcerer's Stone. Harry has a vicious magical duel with rival Draco Malfoy (Tom Felton) and also faces an identity crisis over his mysterious similarities to the evil Lord Voldemort.

"I think it was great to be able to show Harry's dark side," Radcliffe notes. "To show that he's not flawless and that he's not a perfect person."

He adds that this spookier subject matter is no excuse to keep young Potter fans from seeing the film. "It's all in [J.K. Rowling's] book," the actor points out. "If you take away the darkness from the film, then you haven't done the book justice. If they've read the book, then I don't think they'll be scared at all."

Most likely, the only moviegoer truly scared by Chamber of Secrets will be Radcliffe himself. He's discovered he has much in common with his big screen alter ego, and after delving further into the character, he's a bit worried about that! "Gradually, when I keep reading the books, I just find out more about myself that Harry has in his personality too," he reveals. "[Like] curiosity, loyalty, not being afraid to stand up for yourself and getting in trouble... I think I'm going to have to go and have therapy one day."
