According to Avatar: The Last Airbender head writer and director Aaron Ehasz, fans of the animated series would have had a fourth season to look forward to, had he been able to see his plans through.
In a series of tweets, the writer revealed there was a time during the series' run where he and co-creators Michael Dante DiMartino and Bryan Konietzko envisioned a fourth season of the show. However, plans for M. Night Shyamalan's live-action film took precedence over Season 4, and the show was brought to a close.
"I always intended for Azula to have a redemption arc in the story of Avatar: The Last Airbender," Ehasz wrote. Azula, as fans know, was the villainous sister of Fire Nation Prince Zuko. Responding to subsequent tweets, he revealed that he always believed "there would be a 4th season," but it ultimately didn't happen because the creators of the animated series wanted to focus on the film, instead.
"Though to be clear, M Night wanted us to do a 4th season," he explained, "but Mike and Bryan wanted to focus on the movie."

Ultimately, this was a lose-lose for Avatar fans. The 2010 live-action film, The Last Airbender, was critically panned and ill-received by audiences, and the animated series would never get a fourth season.
In recent years, Ehasz co-created The Dragon Prince with Justin Richmond, an animated series currently airing on Netflix. The show was recently renewed for a third season.
In September 2018, Netflix also announced it would produce an Avatar: The Last Airbender live-action series, which will be overseen by the animated series' creators, Michael Dante DiMartino and Bryan Konietzko. However, Ehasz doesn't appear to be involved in the project.
Featuring the voices of Jack DeSena as Callum, Sasha Rojen as Ezran, Paula Burrows as Rayla, Jesse Inocalla as Soren, Racquel Belmonte as Claudia, Luc Roderique as King Harrow of Katolis and Jason Simpson as Viren, The Dragon Prince Seasons 1 and 2 are available now on Netflix.
