This reminds me of a nifty piece of trivia: in the final scene of "Casablanca" Rick is seen walking out of an airplane hanger where mechanics are working on a plane. But since the movie was shot entirely on a sound set, the plane is actually a scaled-down model and the workers are midgets. You can look it up.
Special Viking Pundit note: Des! Did you get my last email? I think your Earthlink address is defunct. Thinking of you and good trivia.
