Harry Potter actor Daniel Radcliffe fears the fictional wizard is taking over his life - because he has started to believe he actually exists.

The 16-year-old star, who has been playing the character since he was 11, loves his Hollywood status, but admits his alter-ego is beginning to eclipse his own personality.

He says, "I have actually started to talk about Harry as if he's another person I know, like one of my friends which is quite worrying.

"And people who have known me for five years have started to call me Harry."
