I'm a big fan of Harry Potter (the books) I've seen all the films too, and to be honest it wasn't very long to wait until it came out in november, and they're delaying it by eight months because if they release it in the summer, they said that "summertime is the ideal window for a family tent pole release” ie they'll get more money that way. It's a pretty lame excuse, Harry potter isn't a film no one's heard of before, it has had five previous films with massive followings, money shouldn't be an object. However they're too busy thinking about their bank balance to care.
