Dan's voice broke before the first film was finished (news story)

[Neil Ward]

Um, I don't think a spoiler is needed on this...

The news report below reveals that Daniel Radcliffe's voice broke 
before the end of filming the first HP film.  A boy called Joe 
Sowerbutts - who is actually  a bit older than Daniel - provided the 
boyish voice for two scenes, and has been hired to voiceover some 
film-related merchandise.

I guess Joe will also be dubbing Dan's voice for the whole of Chamber 
of Secrets... unless *his* voice breaks, that is.
