Before the film was officially filmed, Spielberg had intended to direct the film, but because Spielberg planned to use Hayley Joe Osment to play Harry Potter, the producer insisted on finding a British boy. The actor came to play Harry, and the two sides couldn't agree, so Spielberg had to break up with the film. So the producer launched another director selection, kicked out famous directors such as Tim Robbins, Wolfgang Peterson, and finally chose Chris Columbus.
In October 2000, the film officially started shooting in the UK. In order to produce a well-made work, the film crew has been shooting in nine photography studios in the UK, costing a total of 125 million US dollars. Almost all the adult actors in the film are outstanding British performing artists. The theme song "The Boy Who Lived" in the play will be sung by Celine Dion, and it is the two masters James Horner and Will Jenin who wrote "My Heart Will Go On".
