I didn't really have an image in mind, but was glad it wasn't one of the 'pretty boys' in Hollywood, they are fine for the rest of the family, but Edward needed something a little off the Hollywood line.
Gutted I saw the film before I read the book, because now I always picture him as R.Patz. I feel like the choice has been takem away from me! I think he was a good match for Edward though so not too bothered. It's better he was a pretty small actor and wasn't some huge type cast Hollywood star mind.
