DH 2 spoilers from EW

…An encounter in limbo with Dumbledore’s specter (Michael Gambon), who reveals dark secrets about his past. And, of course, Ron and Hermione’s kiss. ”It has to be the most anticipated moment between the two of them in the whole series,” says Watson. ”In general, though, Part 2 is just plain hell-raising and scary. I get to get my Lara Croft on.”
Both parts of Deathly Hallows were shot simultaneously over 261 days. Keen-eyed Potterphiles will note a number of tweaks to Rowling’s climactic tale. The filmmakers have added a new structure to the sprawling Hogwarts campus — a glass boathouse where a certain iconic character will perish. (Hint: In the book, the scene takes place at the Shrieking Shack.) The final confrontation between Harry and Voldemort — a wand duel in the novel — has been expanded to include a chase through Hogwarts and a very physical brawl as the two foes ”apparate” (i.e., teleport) toward and away from each other. At one point, the rivals seem to fuse, creating a striking, symbolically loaded visual effect.
One of the trickiest sequences for the filmmakers was the movie’s epilogue, set 19 years after the heroes’ graduation from Hogwarts. Director David Yates first shot the scene during the middle of production, with the young stars wearing makeup to look like the adult versions of their characters. ”I didn’t want older actors,” says Yates. ”If you spent seven movies with these guys, you know these kids, and you want to end with them.” But looking at the footage, he felt the epilogue fell short of magical. ”We ended up with a scene that, for all sorts of reasons, not just the makeup, just didn’t work,” says the helmer. So late last December, months after the end of principal photography, Yates called the actors back for a do-over. ”We came up with a very simple solution — simple makeup, which may be enhanced slightly with special effects — that’s really charming.” According to producer David Heyman, the new epilogue also led to a change in the portion of the film that plays during the closing credits. ”We thought about a nostalgic look back at how the kids have grown over the previous films,” says the producer. ”We decided against it because this ending captures all of that.”
Of all the moments in Deathly Hallows — Part 2, the one that may exude the strongest sense of closure comes right before the epilogue, when Harry, Ron, and Hermione stand on a bridge outside Hogwarts, looking back at the school. ”I like it very much because it wasn’t just the actors playing the scene, it was the kids reflecting on growing up in this moviemaking world, and I believe a bit of that has ended up on [film],” says Yates. ”For anyone who knows them or can identify with these three, as characters or actors, it’s quite moving.”
