Avatar Spirits is a Nickelodeon documentary, directed by Kurt Mattila, about the making of Avatar: The Last Airbender. Its total run time is near half an hour, and it describes the creative process involved in the making of the hit television series. To create the thirteen episodes, they brought on more crew members to help out, such as John O'Bryan, Andrea Romano, the Track Team, and many more. Included in these were Sifu Kisu and Sifu Manuel Rodriguez, who provided a basis for the animators to animate the martial arts moves that the bending forms were based on.
