The series' first season was the basis of the 2010 live-action film The Last Airbender, which was written and directed by M. Night Shyamalan. It was intended as the first of a trilogy of films, each of which would be based upon one of the three television seasons. The film was universally panned for its writing, acting, whitewashed cast, and Shyamalan's direction; it earned a 6% approval rating on Rotten Tomatoes as well as five Razzies at the 31st Golden Raspberry Awards, including Worst Picture. Although the film originally shared the title of the television series, the title The Last Airbender was used because producers feared it would be confused with James Cameron's film Avatar. The Last Airbender stars Noah Ringer as Aang, Nicola Peltz as Katara, Jackson Rathbone as Sokka, Dev Patel as Zuko, and Shaun Toub as Iroh.
The Legend of Korra, a sequel series to Avatar: The Last Airbender, premiered on Nickelodeon on April 14, 2012. It was written and produced by Michael Dante DiMartino and Bryan Konietzko, the creators and producers of the original series. The show was initially titled Avatar: Legend of Korra, then The Last Airbender: Legend of Korra; its events occur seventy years after the end of Avatar: The Last Airbender. The series' protagonist is Korra, a 17-year-old woman from the Southern Water Tribe who is the incarnation of the Avatar after Aang's death.
Netflix announced in September 2018 that a "reimagined" live-action remake of Avatar was to start production in 2019. The series' original creators, DiMartino and Konietzko, are to be the executive producers and showrunners. They said that they intended to adapt the series "with a culturally appropriate, non-whitewashed cast". Jeremy Zuckerman, who composed music for the original show, will also be returning to do the music for the remake. The release is slated for 2020.
