Here James Watkins talks exclusively about his film Woman In Black, he says he always wanted to do a ghost story. He said "Jane Goldman’s script for The Woman in Black I really responded to it. I liked the fact that it was very scary but moving at the same time; it had a real depth." Which backs up my statement that UK horror films tend to put more story and suspense in the films.
