Kevin Conway uncredited
I can never understand why actors go uncredited in roles, and I was surprised that Kevin Conway's playing of Crum Petree the mailman was uncredited. It was a such a great character even if he was only on screen for less than a minute.
I guess my question is why was he not listed in the credits? Do films do this in order to create a mystique about an actor/character by making you wonder who he was, just like the character of Crum Petree in the movie?
