Warner Brothers unveiled a batch of clips from the big Harry Potter finale, (Harry Potter And The Deathly Hallows: Part 2) and it sounds like the studio changed a few scenes from the book — specifically the epic end battle.
Warning: This is very spoilery!
There was about four minutes of footage screened, and according to ComingSoon.net the bulk of the footage took place in Gringotts Wizarding Bank (a moment that pops up towards the end of the book). Harry, Ron, and Hermione are riding a bank cart with a goblin (we're assuming Griphook) in search of a horcrux. If you remember the book, the vault that they're trying to break into is owned by Bellatrix Lestrange. But suddenly their cart is blasted, and the kids plummet to the ground.
Later on, a giant white dragon appears and Hermione and the boys jump on its back and end up getting flung into a lake.
Other scenes included Voldermort taunting Harry via voice over, telling him to meet him in the forbidden forest. The Dark Lord taunts Harry by listing off all of Harry's friends that Voldemort has murdered or harmed. Potter heads out to the forest and is intercepted the very dead friends that Voldermort spoke of, including Dumbledore! The two go for a walk in some sort of strange alternate world, where all of the background is white. Purgatory? Heaven? We don't know.
And finally the audience caught a few glimpses of the final battle of Hogwarts. Cinemablend noted that the entire showdown seemed restructured and reshaped to make for a grander display. Snape was now battling Minerva McGonagall in the Great Hall, instead of in a corridor. It also sounded like there was a lot more time dedicated to the Snape moments on screen than in the book. The producer told CB that these changes were made to flesh out Snape's story.
We don't really have a problem with that kind of change! Fingers crossed Harry Potter ends with a bang and not a whimper.
