James Cameron knows very well he is not the only filmmaker to deal with child cast members’ changing appearances over the years. During a recent interview, he explained  why he opted to shoot the recently released Avatar: The Way of the Water at the same time as the third instalment of the series that is scheduled to arrive in 2024, and also some portion for the fourth part, as growth spurts for the younger performers could change the way they look.
