I just got inspired with this song which would need to feature mostly children. It has two parts, the first is very emotional, sad, and hopeful and the latter is very upbeat and more fun, defending that little people can still put up quite a fight.
The kids can but don't have to be the main characters. So far I plan to use some Miyazaki movies (castle in the sky, maybe spirited away at the least), Gakuen Alice, the girl from Mitchiko no Hatchin, the little girl from Kuren-ai, Card Captor Sakura, probably Naruto when they are younger.
Kids going up against adults, being looked down, being laughed out, outwitting adults, or putting up a fight. Kids with sad back stories, getting bullied, crying, or who were abused may be helpful for the first part.
Thinking of kids around ages 12 and under (but may make exceptions - thinking about using Edward FMA for a few scenes... at least he's short and he's got lots of fight in him. ^^)
