Why not film on an aircraft carrier and dress that up a bit for the lower decks?
Why not indeed? It worked for
Silent Running.
Absolutely! But then, Trumbull's crew tweaked things a bit, since the ship was going to be scrapped after filming, i.e. changing the shape of the hatchways, filling the hangar deck with all those nifty cargo pods, etc.
(Fun fact: Apparently, Dow Chemical donated all the plastic to make the cargo pods because they wanted some good press to compensate for their other product, Napalm.)
EDIT: Now that I've read the entire thread, I'm with Zim 100% — totally took me out of the movie.
Of course, my Dad was a set designer, so we always went in for "Design Porn" movies, like
Star Wars, A L I E N &
Blade Runner (especially those two!).
Thanks to him, I go into a big-budget Sci-Fi movie or TV show expecting
every square inch to be custom-designed.
(He passed away just a few months before
Space: Above and Beyond premiered. He would've gone nuts over
those sets!)
When I saw the water treatment plant and brewery in ST09, I thought "What, are we in film school now?"
Not to insult film school, because Lucas took his USC final project and amplified it (with the help of Coppola) into the best example I can recall of making real-world locations look futuristic:
