Designing Metropolis (The city, not the magazine)

Bryan Singer has been keeping a video blog of the progress of his latest movie, Superman Returns, over at bluetights.net. (Not only am I a design nerd, I'm also a movie nerd.)
One of the latest reports shows the work of his graphic design department fleshing out the details of Metropolis. Designing the look of an entire city has to be one of the secret desires of every designer and it is fun/envious to watch them at work.
