Not been discussed here, Dave. (Welcome to the ranks of the converted!) We thought it was sad that they changed it for the US. Tom (14) even had a letter printed in the Guardian about it- it seemed rather like 'dumbing down' for the American market, as if it was assumed that they wouldn't understand the concept of the philosopher's stone...

Graham, my daughter too was miffed that Hedwig's name wasn't mentioned, and I thought they could easily have referred to Mrs Norris instead of 'Filch's cat' as they did at one stage- can't see that it would confuse anyone who hadn't read the books... And Scabbers was far too healthy looking!
