This video includes a slideshow of a bunch of photos of deleted scenes from Prisoner of Azkaban, Goblet of Fire, Order of the Phoenix, and Half Blood Prince that have not been released. They were not in the movies or on the dvds.
They include some really great ones like Dumbledore’s explanation of Priori Incantantem, Hermione and Ron comforting Harry by a waterfall, and Sirius dueling Bellatrix.
Hope you enjoy! I really hope they will be released with the future Ultimate Editions.
