Surveyors' ending shot - v1

Here's the first rough version of the final pullback that ends Surveyors. With Chris and Hayley talking on the elevator platform, Chris says his final line and then there's this major pullback to see his elevator as well as others going up and down in a huge cavern. It might be hard to see in this compressed version, but there are three elements that need to get combined. The first is the closeup live action footage of them talking. Then there's the image of their bodies and the elevator that needs to get merged in with the closeup (difficult since the reference photo for them standing there doesn't match the best take of them talking - their positions have shifted). And then the fully cg background cavern. Fortunately, the shot favors a massive unzoom rather than a dolly back which means that only one high quality render of the cavern is necessary rather than repeated passes from a flythrough perspective. As final touches, other elevators will get composited in as well as the closing box effect that finishes the shot.
