AI had its narrative problems, sure. But it didn't have a problem with the awesomeness of its practical effects, specifically the awesomeness of this fully kinetic, crippled android puppet. It's so good that the robo-carnage is almost disturbing.
This behind the scenes footage come from our friends at Stan Winston School, who put a few of the puppet's operators in front of the mic to explain the whole experience. If operating a giant robo-puppet wasn't enough, the final shoot actually involved burying the operators alive.
Sometimes you've gotta go the distance for badass practical effects. And man, it's lookin' worth it.
