I was pretty annoyes when I found out Harry Potter World was being made in America, on my children's behald obvioulsy, ahem. Am also annoyed that so many books set in the UK are made into American films, was really looking forward to 'I don;t know how she does it' coming out, only to watch the trailer and see it's set in the US. Same goes for Roald Dahl's 'Matilda'. Can't think of any other but am sure there are loads!
