-Lawrence G. Paull
"Things are 'retro-fitted' after the fact of the original manufacture because the old, consumer-based technology wasn't keeping up with the demand. Things have to work on a day-to-day basis and you do whatever necessary to make it work. So you let go of the style and it becomes pure function. The whole visual philisophy of the film is based on this social idea.
"The city was getting very dense. Buildings 3,000-3,500 feet high would have old, ten and twenty story buildings underneath, functioning as service accesses to huge megastructures. Cables and generator tubes, delivering air and waste, would go up outside of the old buildings because they were still there. The street level becomes a service alley to the megastructures towering above."
"Almost as production began, we started building additional miniatures and more buildings, working on a smaller scale so Ridley could have more scope. He'd have the cityscapes in the background that actually aren't buildings at all- but we dressed them up with lights so they looked like they were."
