Here's a sneak peak clip that was shown from the part of the movie where Bella and Jacob finally ride the motorcycles (it's also one of the times in the movie where Edward appears to Bella as an illusion. You know, because when she puts herself in danger he can 'speak' to her). All I can say is that you will not be able to resist the urge to scream or throw your hands up in excitment for this movie.
This second sneak peak clip is from the part of the movie where Bella has to go stop Edward from committing vampire suicide. It's also the part where the fountain (which was not in the book) was added. I laughed a little at this clip because it feels a little too dramatic... and computerized. It's hard to explain. The first movie felt to natural, but from these clips the next movie in the series is looking really different.
