Slade’s favorite deleted scene originally came after a spat between Bella and Edward early on in the film.
When Bella sets out to see Jacob one night, Edward catches her in her truck “and they have a bit of a row,” Slade says. In the final version of the film, Bella simply heads back into the house and slams the door, ending the scene.
“We actually shot a scene where the row continues for a little while and she goes upstairs and she looks at the open window and she closes it,” he said. “Then she kind of has a moment and then she unlocks it and opens it again. And it was really touching and emotional, but it’s like a speed bump every time you hit it. It kind of threw you out of the film.”
