Here's a brief history of attempts:
* 2008: Paramount Pictures acquired the film rights but ultimately abandoned the project after a tumultuous development process.
* 2010: M. Night Shyamalan directed a live-action adaptation that was critically panned.
* 2018: Netflix acquired the rights to both *Avatar: The Last Airbender* and *The Legend of Korra* with plans to develop new live-action series.
So, while there isn't a confirmed movie in the works, it's possible that Netflix could eventually decide to adapt the story for the big screen. The success of the animated series and the recent *The Legend of Korra* live-action adaptation on Netflix suggests there's still a lot of interest in the franchise.
However, it's important to note that Netflix hasn't announced any concrete plans for a *Avatar: The Last Airbender* movie.
