Shaolin Soccer/WMG

This film shows that bending exists in real life.
Specifically, airbending (Mui), firebending (Sing) and earthbending (several Team Shaolin players, esp. Third Brother when he takes a turn at goalkeeping). Just compare the styles in this film with those in the Avatar series.
 * Said bendings were, after all, based on Chinese martial arts afterall(if we ignore the movie adaptation, which is pretty much a hilarious Hollywood Fu)
