The Last Airbender (2010)

The film begins with fourteen-year-old Katara (Nicola Peltz) and her fifteen-year-old warrior brother, Sokka (Jackson Rathbone), near a river at the South Pole. They soon followed some tracks of a tiger seal. When they looked beneath their feet, there was something glowing below. An ice sphere appeared with a boy named Aang and a flying bison named Appa trapped inside when Sokka hits the floor with his boomerang. Unknown to them, Aang (Noah Ringer) is the long lost Avatar - a spiritual figure that holds the world in balance through every incarnation. However, his disappearance allowed the Fire Nation to declare war on the other nations (the Air Nomads, the Water Tribes and the Earth Kingdom) in their attempt to conquer the world. Zuko (Dev Patel), an exhiled prince of the Fire Nation, is on a quest to find the Avatar and bring him as prisoner to his father, the Fire Lord Ozai (Cliff Curtis). Seeing the light that appeared from Aang's release, Zuko and some Fire Nation soldiers arrive at the Southern Water Tribe to demand the villagers to bring out their elderly under the impression that the Avatar must be an old person. But Aang reveals himself as he surrenders himself to Zuko on the condition that he agrees to leave the village alone. On the ship Aang is tested by Zuko's Uncle Iroh (Shaun Toub) to confirm him to be the Avatar.
