The animated series, created by Michael Dante DiMartino and Bryan Konietzko, first premiered on Nickelodeon in 2005. An unsuccessful live-action movie, helmed by M. Night Shymalan, hit theaters in 2010. A trilogy of new animated movies, backed by DiMartino and Konietzko, was announced back in June.
