In 2000, after a seven month search, lead actor Daniel Radcliffe was discovered by producer David Heyman and writer Steve Kloves seated just behind them in a theatre. In Heyman's own words, "There sitting behind me was this boy with these big blue eyes. It was Dan Radcliffe. I remember my first impressions: He was curious and funny and so energetic. There was real generosity too, and sweetness. But at the same time he was really voracious and with hunger for knowledge of whatever kind."
Radcliffe had already established himself as an actor in the 1999 BBC television production of David Copperfield in which he played the title role's childhood years. Heyman convinced Radcliffe's parents to allow him to audition for the part of Harry Potter, which involved Radcliffe being filmed. Heyman stated in an L.A. Times interview that this historic screen test of Radcliffe will be released as bonus material on a subsequent Harry Potter DVD. The footage was eventually released via the first set of Ultimate Editions in 2009. Rowling was enthusiastic after viewing Radcliffe's filmed test, saying she didn't think there was a better choice for the part of Harry Potter.
