Avatar will have an animated movie in 2026, featuring the original Gaang characters but with an entire new voice cast .

“Steven Yeun was Avatar Wan,” Konietzko said. “He played the first Avatar in The Legend of Korra. We loved working with him and we’re excited to have him back in the universe.”

The natural follow-up question is whether Yeun will also be playing Avatar Wan, but neither Konietzko nor DiMartino would budge on that one.

Yeun joins previously announced cast members Dave Bautista (a so-far unannounced villain), Eric Nam (Aang), Dionne Quan (Toph), Jessica Matten (Katara), and Román Zaragoza (Sokka).

The Legend of Aang: The Last Airbender, due out October 9, 2026, is said to focus on the original Avatar protagonist in a story that takes place many years after the series came to an end.

It’s a busy time in the world of Avatar. Also at Comic-Con, DiMartino and Konietzko revealed the first image from Avatar: Seven Havens, a 26-episode animated series following a young Earthbender who is the next Avatar following Avatar Korra.
