If the shooting of Harry Potter and the Chamber of Secrets, the second part of the saga, did not start until a few days after the release of the first film, the team found itself faced with a very singular scenario: the change of voice of its main performer… in the middle of filming! Daniel Radcliffe , 12 years old at the time, was indeed surprised to hear his voice change between the beginning and the end of the film… Puberty, when you hold us

In order not to have “voice” differences between two scenes, Chris Columbus and his team had to find an emergency solution. Daniel Radcliffe’s voice was therefore deleted in post-production to be replaced by a new one. And it is in the hope of finding the rare pearl that the casting team embarked on a last minute mission. It is finally the young Joe Sowerbutts , 13, who was chosen to lend his voice to Daniel Radcliffe, in some scenes of the second opus (including one in the Forbidden Forest) as well as in the derivative video games.

In an interview with The Guardian in 2001, Sowerbutts recounted this funny adventure: “I couldn’t believe it when they told me I was going to be in the movie. I was really surprised that Daniel’s voice has changed because he’s younger than me. But, you could say that it was a stroke of luck for me “.
