'An American Tail'
This film begins with a Hanukkah celebration where a young Russian-Jewish mouse named Fievel learns all about the great United States from his father. America is a place where there are supposedly no "cats" to attack them for simply being who they are. Of course, once Fievel goes to America, he learns that there are cats everywhere, but he perseveres.
It's an important analogy of the realities of anti-Jewish discrimination as told through a rated-G children's movie.
