Emily and Charlotte just sent us the following report:
We went along to the POA filming in Palmers green yesterday and got chatting to a man working on the film; he was telling us some of the scenes that had been shot already - the aunt Marge bit is slightly different from the book, apparently she floats out into the conservatory and then into the sky, Uncle Vernon grabs her ankle and the dog jumps at his. Also ... they've kept ... Snape dressed in woman's clothing when the students have their lesson about boggarts with Lupin. Oh and apparently the models of the Dementors are really scary.
Obviously, the comments from the staffer are secondhand, but if it proves to be accurate *and* makes it into the film, it should be interesting!
