Netflix is going forward with its live-action Avatar: The Last Airbender series—regardless of whether fans and the original creators Michael DiMartino and Bryan Konietzko want it to or not. The streaming giant announced the primary cast back in August, and now we know which actors will play three of the supporting characters, too.
Fan-favorite and tea-loving Uncle Iroh will be played by Kim’s Convenience star Paul Sun-Hyung Lee. It’s a perfect fit for Zuko’s endearing uncle, since, despite the show’s writing flaws towards the end, Sun-Hyung Lee managed to always make his Kim’s Convenience character Mr. Kim charming.
