Ananova:

Daniel Radcliffe refuses to watch the first Harry Potter film - because he cringes when he hears his unbroken voice.

The 14-year-old caught a snippet of 2001's Harry Potter and the Sorcerer's Stone on television recently, and wishes he hadn't as his voice was so high.

Radcliffe, who has just finished shooting the third film, Harry Potter and the Prisoner of Azkaban, told Empire: "I haven't seen the first one in a few years. I don't want to watch it. I won't go back while I'm doing the fourth one.

"Actually, I was flicking through the channels one day and I saw a bit of the first film and I genuinely thought there was something wrong with it.

"It sounded like I was on helium, it was bizarre, and I genuinely thought there was something wrong with it."

Harry Potter and the Prisoner of Azkaban will be released in the UK on June 4.
