Early Joker Concept Art for ‘The Dark Knight’

Heath Ledger's ghoulish Joker makeup gave me the heebie jeebies. But he looks like a squeezable birthday clown compared to this grisly concept art. Some of these images, found in The Art of The Dark Knight, were created before Ledger was cast -- back when names like Crispin Glover, Lachy Hulme, and Paul Bettany were bandied about. Ledger's knife-wielding clown was a frightening cat, but this joker would have sported a chainsaw.
