"They filmed it down in Wexford and I visited the set for about half an hour. I don't usually go near the set, because there's nothing for a writer to do there and you're constantly getting in the way. If I give a book to the movies, it's theirs. Writers often whinge about being betrayed by the movies – I have no sympathy for that. If you don't want a movie to be made, then don't sell your book to the movies."
