Hayao Miyazaki was still so upset by the 'Warriors of the Wind' version of Nausicaa that when Harvey Weinstein was threatening to do a similar heavily cut version of Princess Mononoke (1997), Miyzaki sent a katana to Weinstein with 'NO CUTS.' embedded into its blade.
After the heavily re-written and edited 1985 release of this film in the United States and Europe (as "Warriors of the Wind"), which substantially changed the movie in addition to cutting nearly 25 minutes of footage, Hayao Miyazaki was hesitant to release any of his film's outside of Japan. 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.
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.
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.
While many consider this to be a Studio Ghibli film, it was actually created before the studio was properly founded, and is instead a production of Topcraft. Studio Ghibli was officially founded in 1985, and its first production was Castle in the Sky (1986).
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. Also, Asbel in his red gunship resembles the Red Baron, the dreaded German fighter pilot of WWI.
Patrick Stewart who voiced Lord Yupa also played Captain Jean-Luc Picard in Star Trek: The Next Generation. Captain Picard had an artificial heart that he needed installed after a run in with a Nausican (s06e15 "Tapestry).
The disastrous "Warriors of the Wind" dub left its cast without any billing. Among the unnamed actors from that cast Cam Clarke was Asbel (name changed to Milo) and Susan Davis was Nausicaa (name changed to Zandra).
