That’s Avatar: The Last Airbender, not Avatar (the long gestating James Cameron sequel)…
Paramount and Nickelodeon are preparing three new animated Avatar movies with Lauren Montgomery directing the first. Franchise creators Bryan Konietzko and Michael DiMartino are producing.
“As original creators Mike and Bryan expand the Avatar universe with us, we’re keeping it all in the family with Lauren bringing the same kind of expert, beautiful work she did on the original series to her new directing duties on the forthcoming theatrical,” said Ramsey Naito, who serves as President of Animation & Development at Paramount Animation and Nickelodeon Animation.
