Ladies, go out and rent The World Changes because Paul Muni is gorgeous! If you thought he was handsome as a brunette, just wait until you see him as a blond. Of course, by the end of the film, he's undergone severe age makeup, but feel free to drool your way through the first half of the film.
Paul lives out in the country with his family, but a chance meeting with Buffalo Bill, played by Douglass Dumbrille, inspires him to explore and make his way in the world. He gets a job in a meat-packing factory, and after marrying the boss's daughter, he transforms the industry. In addition to showing one man's struggle in the business world, the movie explores themes of ambition, ingratitude, family quarrels, and marital problems. Parts of the film are very good, but keep in mind that it was made in the early 1930s. It's worth noting that this was the first film Paul Muni made in which his character aged decades, something that would become his signature throughout his career.
Enjoy the eye candy, and the supporting cast, including Mary Astor, Guy Kibbee, Aline MacMahon, Margaret Lindsay, and Donald Cook, but you might want to watch a musical afterwards. The film takes place over several decades, and each time change shows a globe turning. The scene-change music can get stuck in your head quite easily.
