There was also input from writer/director Frank Darabont, who gave a pass on the script "about two or three months before we started filming", according to Edwards. "A lot of his work remains in the film, but a big part of it is when the doors close on Juliette Binoche; this whole idea that there’s a gateway or a check point they have to get through, and that it would close, and you would see her die, and we’d have that very emotional moment. That was his biggest contribution. It’s the emotional peak of the film, potentially."
That explains why that whole sequence seemed to come from another movie. It was arresting visually and emotionally, and heartbreaking. Maybe he can let Darabont write the next script solo
