In visualizing the Potter books, the movies have had their ups (David Yates’s athletic opening sequence to Order of the Phoenix, Alfonso Cuarón’s cheeky Whomping Willow in Prisoner of Azkaban), and their downs (Mike Newell’s overblown pathetic fallacy in Goblet of Fire, everything except Kenneth Branagh in Chamber of Secrets). If the many trailers for Deathly Hallows are any indication, this one should have more of the former than the latter. Are there any moments you’re particularly excited to see realized on film? And is there anything that you fear will be botched?
