What are your favourite parts of the movies which weren't in the original books?

I really like how they did Jake's imprint at the end of Breaking Dawn 1, and flashing forwards sort-of to explain it. I liked the scene of him kneeling there. Also the vision of Alice's at the end of Breaking Dawn 2, and showing the battle through her vision (though I actually don't understand how she could see either).

I also liked the additional scenes in Eclipse, showing things like Riley's transformation and the newborn army developing.
