Kristen Stewart says the split point in 'The Twilight Saga: Breaking Dawn' films is 'obvious'

'Breaking Dawn' by Stephenie Meyer - Hachette Books

A few days ago, the question of whether there was a desirable point in the story of Breaking Dawn where the films could effectively be split came up, and the comments suggested that there were mixed but similar opinions about the moment.
Kristen Stewart, however, has been quoted to say that the split point is rather "obvious."
"I feel like it's so obvious where you break it up. It's as soon as she turns," she said to the Associated Press. "Gosh, you open your eyes to this different world, right? That would be amazing."
When producer Wyck Godfrey talked about the idea of making the second Breaking Dawn film a three-dimensional movie, he mentioned that the idea would be "when she becomes a vampire we move into 3D."
It seems, then, that the line has been drawn in the sand for the split of these two films and that the point of Bella's transformation may just be the carry-over after all.
