The new trend is taking Anime and making it into live action movies.
So far, this trend has been terrible. Dragon Ball Evolution was a joke.
Aang is supposed to be a hardcore little Chinese boy. The Chinese thing is rather important as well. So, in live action, let's make him American and forget about the whole story?
Not so sure.. We'll see though.
Not Avatar: The Last Airbender; this is a different movie!
