"You've seen the Hunter-Killer before in the first three movies. So in the same way that we're coming back as it were from the T-800 to the T-600, we're doing the same thing with the Hunter-Killer. It's a little bit more brutal in its shape. It still has the vertical take off and landing design that was established in the previous films. But the shape and the colouring is very different. We were really lucky to have so many great designs to start with in the original Terminator movies and then we're working backwards to give it more of a brutal, basic feel. In the very early conversations I had with McG he was pushing an idea of a kind of cool silver look, then we came up with the idea of doing everything in black, and it all really started gelling."
