Check it out here! An excellent piece about filming on Potter three, by Martin Barber. Quotage from Chris:
His style is completely different to Chris Columbus?, he?s going for a real dramatic, tension building to a climax kind of film which I think is going to be perfect for Potter three. I think the way Alfonso is doing it, the way he?s shooting it, the style of camera work we?re using ? just everything is reflecting a slow and dramatic build up to an amazing end.
