According to Penn State, "In 1974, in preparation for the American Bicentennial, the American Iron and Steel Institute made a half-hour film in cooperation with Walt Disney to promote an understanding of industrial society. The film told the story of American steel making from its primitive beginnings to recent practices and future needs. Scenes of colonial iron manufacture, modern steel plants, and steel products are interspersed with scenes of Donald Duck doing what he does best: being a good worker, getting run over by wheelbarrows, and getting frustrated. This scene, about 10 minutes into the film, explains how iron is mined and smelted in the Middle Ages—and it ends with Donald's literal transformation into a colonial ironmaster."
