The cast of Avatar: The Way of Water includes Jack Champion, who is now 18 but started filming at the age of 13.

During a recent Entertainment Weekly interview, the filmmaker offered further context for his decision to shoot his sequel, Avatar: The Way of Water at the same time as the franchise’s third film, scheduled for a 2024 release, and a portion of the fourth movie, given that growth spurts for the younger performers could change the way they look.
For example, actor Jack Champion, who plays Spider in the films, was 13 when The Way of Water began shooting but is now 18.
Champion praised the connection he formed with Cameron over their four and a half years of filming. “He’s just a cinematic genius,” Champion said. “After so many years, he has kind of become like a father figure to me.”
Champion said that watching The Way of Water can feel like a “time capsule” given that he has been growing up in front of the cameras: “So it’s cool to see my teenage years onscreen, but I can still get immersed in the world of Pandora.”
