Cujo is mentioned in book 7. Roland thinks to himself that the word means "dear heart" or "sweet one" I can't rmemeber which.
Yeah, Whoopi for Sus 10 years ago. Now? Today? Queen Latifa, cause she's hot in that ass kickery way.
I can't see Roland being cast as any currently known actor. Like Superman Returns, he'd have to be a relative nobody.
But I absolutely cannot agree to Costner as Roland. Sorry, can't be.
