People are always intrigued with looking at the detail. Pilots that have flown a B17 in World War II have models of B17s. It's a fascination. There's definitely that theme that's starting to come in. But we're now seeing things that are starting to kind of cross that line.
Designs adapt and improve as the story progressed.
A starfighter design originally intended for evil-doers in the film found its way to the good guy's arsenal, allowing Duncan to craft a model that would have otherwise gone discarded. If it doesn't work for one use, it may look great for another. I know they did that for a number of the creature designs where they started making something for one thing, and then George suggest that by scaling it down, it could be used for something else. There's a lot of fantastic artwork on the unapproved wall. And a lot of times they went back to it.
