The 15-year-old star - who plays the boy wizard - accidentally caught a glimpse of himself in the 2001 movie while changing TV channels, but immediately turned it off because he hated the sound of his voice.
He explains, "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.
"Although having said that, I was flicking through the channels one day and I saw a bit of it on TV and I genuinely thought there was something wrong with the sound because my voice was too high and I seemed so young.
"I might watch it one day for fun - although I'm not sure how much fun it would be because I'm really self-critical."15/12/2004 13:18
