When the creators of "Avatar: The Last Airbender" decided that they wanted to have accurate martial arts in their show, they needed to find a martial arts choreographer and stunt performer. They would film the stunt actor performing martial arts movements, which the animators could then use as reference footage. The person that they ended up picking was Sifu Kisu, an all-in-one master martial artist and fight choreographer. Kisu worked alongside the directors to create the intricate martial arts movements for each character. Director Giancarlo Volpe said that having a stunt performer working on the show ended up saving time overall because it reduced the time spent drawing character movements.
