After the original, heavily re-written and edited 1980s release of this film in the United States (as "Warriors of the Wind"), which substantially changed the movie, Hayao Miyazaki demanded that any new licensor for his films be contractually bound to do no edits whatsoever aside from a straight translation and dub. Disney (who bought the rights to all of Miyazaki's films except The Castle of Cagliostro (1979)) has honored this stipulation.
Many of the pieces of technology that the Tolmekians use bear a passing visual resemblance to German technology from the WWII era. For example, their large transport airships are visually similar to the ME 323 "Gigant" transport plane, their weapons are reminiscent of FG-42 paratrooper rifles, and their tanks appear similar to Sturmhaubitze 42 assault guns.
The lack of color fidelity used in certain versions give many people the impression that Naushika flies around in a miniskirt with a bare butt. This is not the case, she's wearing pants that happen to be roughly the same color as her skin, and the "skirt" is actually the lower part of her coat.
Adapted from the first two volumes of the original manga which Hayao Miyazaki wrote and drew for Animage from February 1982 through March 1994. He took breaks from working on the manga & worked on the earlier anime films he did. The manga is longer and more complex than the movie, featuring many more characters and places.
