Trivia
Noah Ringer submitted an audition tape of himself doing martial arts with a completely shaved head with Aang's signature arrow tattoo painted onto his forehead to Paramount Pictures. This video is what won him the role.
Another "giant change" M. Night Shyamalan made from the animated series to the big screen was to limit the Fire Bender's source of fire. Only the highest of the Fire Benders can conjure flames from their chi.
During the scene where Aang is being tested by Zuko's uncle Iroh, Iroh pours a cup of water onto the table and it coalesces into a circle (at around 26 mins). In the next shot, Iroh places a rock on the table where the water had just been (at around 29 mins), but the water has inexplicably disappeared.
During the first conversation between Fire Lord Ozai and General Zhao we can see that Ozai's eyes move from left to right while he looks in the direction of Zhao's chest, thus revealing the use of a prompter.
When the flying lemur jumps on Aang's shoulder, Aang's hands supposedly touch and pet the Lemur. But it is clear that the lemur is computer generated as Aang's hands do not actually touch the creature, they seem to hover about an inch or so above him.
