Seabiscuit. Seabiscuit is based on the true story of a small horse by the same name during the Great Depression. In the movie, the jockeys like Tobey Maguire wear plastic lenses and chinstraps attach to their hats. The lenses began to be used after WWII and the straps were not introduced until 1956.
