Brother Bear is a Disney film set in prehistoric North America after the last Ice Age, featuring Native American brothers, especially Kenai, who's turned into a bear, learning about life and brotherhood; while not an Ice Age movie (like the Blue Sky fran-chise), it shares themes of prehistoric life, megafauna (like mam-moths), and features a similar prehistoric setting, making people associate them, but they are separate films with different characters and stories, though both involve animal transformation and primal settings.
