The multiplexes are already full of American movies and American superheroes. Why make even the Potterverse yours? There have been so many great recent films (In order of disappearance, Intouchables, Death at a Funeral) that have been turned into substandard murrican versions that those of us in what is actually often referred to as ROW (rest of world) are a bit fed up. So J K Rowling gets all CGI-d up and Eddie Redmayne is roped in to play the blithering, Hugh Grant style English chap. Lots of crashy bashy chase scenes and none of the subtleties of the Harry Potter movies. Good if you cant sleep though.
