"The Hydrobot is a Terminator that actually goes through the water. Although it actually has the fluid movements of an eel or a fish and it has this ability to swim quite quickly we've tried to keep it real again. It's all mechanical, with a rhyme and a reason behind each element of the design. We did the final design, blew it up to full size and then gave it to the guys at Stan Winston Studios who made it as a 3D model. It's about eight and a half feet long. They puppeteered it on set a few days ago and it really looks very exciting. They move it around like a Jim Henson puppet with green sticks which we'll remove digitally. That reality of actual mechanical parts, that really would work, is what we've been chasing with all the design. There's no kind of science-fiction silliness that's going on. We started with Mother Nature, really, looking at various aquatic life, eels and so on. Then we worked on several different designs, honing it down each time. We're trying to establish a reality here. McG has been very clear about the fact that this is a real, grimy, dirty and dangerous world."
