Bullet Time was just the beginning. F/x guru John Gaeta reinvents cinematography with The Matrix Reloaded. I'm sitting in a former naval barracks in Alameda, California, watching the digital assembly of a human face. Bones, teeth, glistening eyes. Layer upon layer. Finally the hair and skin, the creases and tiny scars that make us who we are. The face blinks and breathes. Then it snarls, and my skin crawls.
