“Bullets fired at the “liquid metal” robot resulted only in a chrome-looking bullet splash that momentarily staggered the killing machine.”
The T-1000’s chrome bullet wounds were foam rubber, vacuum metallized and packed under spring trapdoors in a fiberglass chest plate. A pin on a cable popped each one on cue. Stan Winston’s crew got the shapes right by firing into mud. Thirty years later it still looks better than most of what a render farm spits out.
