Fan Casting Cortana in Neil Blomkamp's Halo

The Pillar of Autumn's shipboard AI, stored on a translucent chip no larger than a credit card. She is sharp, witty, and deeply intelligent, manifesting as a holographic woman with glowing blue circuitry beneath her skin. Hardwired into Master Chief's suit—and by extension, his mind—she experiences his dreams and impulses. Her arc moves from clinical efficiency to genuine emotional connection and protective fury.
