The creators of "Avatar: The Last Airbender" say that the new spinoff series "The Legend of Korra" will be more mature than the original show, but will still have the same sense of fun and adventure.

Nickelodeon, the network behind the original show, today announcedthat it will air the "Avatar" spinoff series "The Legend of Korra" (a working title) starting next year.

The first series took place in a world in which supernatural "benders" have the ability to manipulate the elements of air, earth, fire and water, and focused on Aang, a young airbender who turned out to be the Avatar, a person capable of controlling all the elements. The new series takes place 70 years later in the same world and follows the new Avatar, a teen girl named Korra who has learned to bend earth, water and fire and seeks to master air under the tutelage of Aang's son, Tenzin.

Earlier this summer, director M. Night Shyamalan released a live-action theatrical version of the first series called "The Last Airbender" that was poorly received by critics, although it posted respectable numbers in early box office returns.

Michael DiMartino and Bryan Konietzko, the creators of "Avatar: The Last Airbender" and "The Legend of Korra" took the time to talk to Speakeasy today about the new series.
