I think any good literature, whether it's for children or for adults, will appeal to everybody. As far as children's literature goes, adults should be able to read it and enjoy it as much as a child would.
A lot of people in the film industry are fatalists who think a worthwhile film will always achieve its destiny, and the films that aren't worthwhile won't. It's all sort of pre-determined, etc. And I don't think that's true at all.
