Escape from Tomorrow
Filmed at Disney World without permission, it exposed what really happens behind the scenes at the theme park including manufactured corporate happiness and the trouble with having to be happy all the time.

Live action mixed with animation mixed with romance, violence and death. You'll never look at a cartoon the same again.
