Leave it to Winfrey to make a Disney movie even more magical. Her role as Eudora, Tiana's (Anika Noni Rose) mother in The Princess and the Frog, not only added some more star power to the already talented cast, but it allowed Winfrey to be part of something historical — the animated film featured Disney's first-ever black princess. You really thought Winfrey wasn't going to be part of something as culturally important as Princess and the Frog?
