If you know the books, and hell, even if you don't, I'd definitely recommend checking out the radio series. It's really very good. Of course, Peake's writing makes the story, which is why adapting it is never entirely successful, but this one is the best it could be, I think.

Hee, it's Gormenghast. You have a misplaced 'h' :)
