I’m not sure any movie company is brave enough to do another ATLA/TLOK due to the huge amounts of negative fan reactions – even 2 years after the movie came out folk are still spreading the hate that isn’t necessary…. >_< …
Though personally part of me, would love to see more of the ATLA and even TLOK worlds brought into live acton there is another part that's just like… please don't lol….
Finding the right folk to play the characters would also be a great challenge and getting the fans support for those characters would also be another full on challenge indeed.
Bryan and Mike both mentioned that they would love to do a full length movie feature Animation Movie… so one never knows maybe after doing the series they do a Korra Movie…. oooooo, that would be awesome
