James Cameron, the director of Avatar: The Way of Water, said that he wanted to avoid the Stranger Things mishap. He said that the young cast members of Avatar: The Way of Water are growing like weeds, and it was important to take their shots in that period to avoid them looking older in Avatar 3 and 4.
Tuk (Trinity Jo-Li Bliss, who was 7 when cast and is now 13) and Spider (Taylor Tomlinson) are introduced in the film The Way of Water (Jack Champion, who was 12 when cast but is now 18). Cameron explained that Jack Champion was growing rapidly, which necessitated filming the whole second, third, and opening acts of the fourth movie simultaneously.
That is the reason James Cameron decided to shoot Avatar 3 and Avatar 4 scenes with Avatar: The Way of Water shooting.
