Steven Lang's Colonel Miles Quaritch is one of the most complicated characters of James Cameron's Avatar franchise, with shifting loyalties that are only exacerbated by his fate in Avatar: The Way of Water, in which Quaritch changed from a normal human into a "recombinant" Na'vi in a totally new body. According to Cameron himself, Quaritch's conflicted nature will be an important part of the upcoming Avatar: Fire and Ash.
"Quaritch is undergoing an identity crisis. His interest in the biological son of his biological precursor form is all about trying to define, 'Am I a completely new person? Am I bound by the rules and the behaviors of the person whose memories and personality I was imprinted with?' It's a true existential dilemma for him in the philosophical sense," Cameron tells Empire.
