Here's another behind the scenes video from Terminator 3: Rise of the Machines from Stan Winston School. The video features the first Terminators that were built, which were the robotic T-1 tanks that ended up turning on their human creators. The video gives us a cool look at the process of creating these robots.
For Terminator 3 Stan Winston Studio built five T-1s, two of which were fully functional, hydraulic robots with a huge range of movement.
