Fan Casting Albert Ganz in The Safdie Brothers' 48 Hrs.

A feral product of the foster system, Ganz is an unblinking void with a child's glee in destruction. Radically dissociated—pale, sinewy, eyes that register people as objects—a man who kills not from rage but from a terrifying, casual indifference. He stole Cates' gun, he's having a real good time, and he will not stop until the money or the bullets run out. His unpredictability makes him the purest agent of chaos.
