After seeing the actor au for Voltron and @avatarsymbolism and I’s conversation, I decided to make one for ATLA:
The cast is one big happy family
Sokka and Katara are brother and sister, while Zuko and Azula are not (though they act like it)
Katara never auditioned for her part and had never acted before but when she went in to read lines with Sokka, the directors loved her so much they casted her on the spot
Toph is actually blind and her scripts are all written in braille
Both Aang and Toph are child actors and Iroh is the most well known. The rest (excluding Katara) all dabbled in having minor parts on other shows
The cast keeps an “honor count” to see how many times they can get Zuko to say honor on set (it’s well past 100)
They also have a war to see who can mess up the most while filming
The special effects team loves to play jokes on the cast too. When Zuko pretends to firebend, farting sounds come out instead. Safe to say everyone dies laughing
After their first kiss on screen, Sokka and Suki started to date off set
Aang adopted a dog and cat, naming them Appa and Momo respectively
At comic con, Toph loves to spread around rumors when asked questions
And as a joke at comic con, they like to cosplay a different character from the show, ie. Zuko as Sokka, Katara as Azula….
Zuko and Azula have to wear contacts. Her eyes are brown, while his are blue
Even after the show ended, everyone stayed great friends and hang out regularly for coffee and tea
Also, under heavy make up, Zuko, Katara, Sokka, Aang, and Toph all guest starred as their older selves on Legend of Korra
