Here are some ideas:

-Bend it Like Beckham
-Akeelah and the Bee
-West Side Story
-Remember the Titans (not sure if it's age appropriate?)
-Princess and the Frog
-Home (coming out soon -
)
-Annie (coming out soon)
-Earth to Echo (out now)
-Color of Friendship
-The Cheetah Girls movies
-Jump In! (Disney original)
-Dora movies/TV shows
-Mindy Kaling Project is likely too adult, but she's a good role model. Writer, comedian, has her own show...hilarious smile

Movies that highlight different countries/cultures:
-Aladdin
-Around the World in 80 Days
-The Kite Runner (may not be age appropriate)
