"This is my fourth or fifth film that’s been an adaptation of a book, and I hate to admit it, but this is the first one I’d read before filming the movie. Usually I kind of keep the script [as] the bible and base everything off of that. But I think Stephenie probably had a big hand in Andrew’s adaptation of her book. I knew that they were going to try to keep as close as possible and I knew the book would give me much more backstory — just because of the capacity a book can hold — than the script could give me. So I did just crash through the book in a few days. I learned some stuff, and then some stuff changed in the movie, and it all came together, and I was really happy with what we came up with for Ian."
