The world's first snowmaking machine was invented for the snow seen at the beginning of the movie. The invention, by Warner Bros technical director Louis Geib, consisted of three rotating blades that shaved ice from a 400 pound block, and a high power fan that blew the resulting particles into the air. The invention spurred the development of more sophisticated machines that went on to be used at ski resorts around the world.
