Question: Has anyone verified that Christopher Guest has six fingers on his right hand in every scene? There are a few shots (other than the one showing off all the fingers) where his right hand is visible, but the black gloves make a finger count difficult.

Answer: Not meaning to shoot down your idea, but since he is wearing gloves, even if the gloves only had five fingers, it would still not be a mistake as he could easily tuck his two smallest fingers into one of the glove's fingers. I would guess that this is why he wears gloves throughout the film, as the director would surely not have gone to the trouble of making 6-fingered gloves, and the actor does not really have 6 fingers.

They did make a six fingered glove. It's visible when Count Rugen knocks Westley out with his sword. Just before that Westley observes "You have 6 fingers on your right hand. Someone was looking for you."
