It's interesting to see how the Special Features show about the creation of the TV show, and not the movie. They even show how it was based on martial arts and Asian philosophy, and show really cool art from the show. Also, they have some deleted scenes, which show Sokka acting more like he did on the show, as a goofball in some weird dance scene in the Earth Kingdom, and not as some super serious guy. There was also a funny scene when Aang visits a shaman who says she can talk to the dead, but she really can't, which leads to actual jokes and gags, with Aang actually making expressions like he did in the show. Although the Kyoshi Warriors scene is mysteriously missing here, you do get a small glimpse of them as they say goodbye to Sokka.
There was also a gag reel, which wasn't very funny, but neat to see the actors and staff smile and have fun.
As for the movie, well, it's also in Spanish.
