<span class=normal>The films vfx supervisor Scott Farrar has a very interesting tale to tell about using poles as spatial proxies in shots involving computer generated (CG) robots like Optimus Prime - which were only added in the post-production much later.. It is very sophisticated! It is a window washer pole! I believe in low tech for high effect. How it works is like this…if you have robot and I want the actor to look at the robot then you could have a big head (to represent the robot); but those are really heavy. So we just have the pole and the actor uses that to get an eye line.</span>
