On a related note I don't see how they could translate the characters' clothing to live action and not stay true to the cartoon without making it look costumey. A female bounty hunter with DDD tits running around in yellow hot pants and suspenders? Riiiight. Not that I have anything against what she wears, I just can't see an actress actually wearing that getup and expecting her portrayal to be taken seriously.

Then there's Jet's facial hair. Spike's green hair. Ed's weird facial expressions. Sometimes I think they could do better simply by doing the whole movie in CG (actually I feel the same about the Dragonball, Akira, Trigun, and World of Warcraft movies that are also in the works.).
