Sorry, this is the best screen cap I could do with an enlargement. Saw this scene early on in Terminator 3: Rise Of The Machines. Of course, most people were focused on the ancestor of the Aerial Hunter Killer... I always check out the backgrounds as well. It looks like an early version of the T-800 endoskeleton.
Does anyone know if that was an actual prop? Are there more pictures of it? Better quality pictures? It looks cool.
