A movie to show discrimination for kids?

[ida]

What is a good movie to show for kids to learn the evil, or acknowledged the existence of discrimination? I want a group of kids ranging from the age of 6-12 to watch a movie over it but I am not sure what would be appropriate, even cartoons are fine. Please help me out.
