We do already have a "Jaws" Blazer (coming along nicely) and the "Dante's peak" Sub (hopefully goes as well). I could see a "Red Dawn" build, although I'm not sure how many people would recognize the end result without being told.
"Fall Guy"...definitely been done more than a few times. The biggest problem with that truck is which version do you build? How religiously do you follow some of the details? They used both the pre-81 and post 81 trucks throughout the show's run. More than a few still screen shots show massive engine relocation for better balance 'in flight'. As I see it, there are "Fall Guy" attributes, but they're pretty generic. Color, stance, the rest can be pretty much whatever.
So what other movie square body 'builds' are there?
