Now, there's 4 threads on here for Harry Potter, 3 of them I created, two of them for the new movie alone.....
But I'm not sure which one it was where someone said that the new movie was basically setting up the final movie.
So one special note before I continue, anyone who hasn't read the books or seen the new movie yet, please do not read the spoiler box below!
In book 6, while Harry is at the Burrow and talking to Bill and Arthur, they tell him that Ollivander the wandmaker has closed his shop and disappeared without notice. There was no other mention of him after that. Not until in book 7 that is, when Harry makes it back to the Burrow and his scar links him to Voltemort yet again, and he sees Voltemort torturing the wand maker.
Now in the new movie, The Half Blood Prince, at the beginning of the film, it is showing downtown London. A number of executives are in an office building and they're looking out the windows at the sky, where the clouds are getting darker. Suddenly, 3 trails of smoke burst out of the clouds, flying through the streets of London, where they make their way to Diagon Alley. And they blast through a shop, bringing out the shopkeeper, who's head is covered, and they fly off with him. We would have to assume this is Ollivander and a setup for the final movie.
