I've always wondered about this -- When Petofi's hand is detached, it is pretty normal looking, smooth skin, almost youthful (if a disembodied hand can be youthful), nothing too scarey about it. But, as soon as it gets re-attached to the Count, it suddenly looks shriveled and wrinkly, totally fake.
I think the make-up department really goofed up on that one. Why would they choose to make an artificial hand look real, and make a real hand (Thayer David's) look fake? It looks like they sprayed David's hand with some sort of latex wrinkle make-up to get the effect. But, I think it was a bad decision.
Has anyone else ever noticed this?
