movie trivia: scaled down

Because the film was made during WWII they were not allowed to film at an airport after dark for security reasons. Instead they used a sound stage with a small cardboard cutout airplane and forced perspective. To give the illusion that the plane was full-sized, they used little people to portray the crew preparing the plane for take-off. Years later the same technique was used in the film Alien (1979), with director Ridley Scott's son and some of his friends in scaled down spacesuits.
