I mentioned in a past comment a while back that I made a catalog of my anime. One of the observations I found while making it is that everything except for one movie had an entry on the English language Wikipedia already. That movie is Gundress from 1999. According to my personal journal, I watched this once back in 2014, apparently, but I remembered nothing about it, so I loaded it up recently and rewatched it.

The movie has that "sort of hard to follow if you don't already know the source material" kind of feel -- although I think this is the original work? I checked the Japanese Wikipedia entry about it after watching it. Sticking the article through a translator, there's a description of a seriously screwed up initial showing and mismanagement of production with the film being finished after it aired in theaters initially. The version I have is finished, of course; if half the movie wasn't colored in I'd definitely have remembered that!

The DVD menu prominently credits it as "Masamune Shirow's Gundress", but I'm not sure what his role in the production actually was. He's listed in the opening credits for 設定協力 which got translated to English as "Characters Designed by" -- but different people are credited with character and mech design in the end credits. A literal translation is something like "setting cooperation".

There's definitely a number of familiar elements with some buildings reminiscent of Dominion Tank Police, mech suits that reminded me of designs in GitS:SAC, as well as thermoptic camouflage, cable-based cyborg communication (jacked into the neck), cyberdiving, etc. coming up during the story.

Unusually, this anime features a Little Arabia enclave within the Japanese "Bayside City" the story is set in and one of the main characters is Muslim. I think this may be the only time I've seen Arabic script in anime -- although I don't know what it says.

I clipped some screenshots and stacked them up so you can see what it looks like, if you're curious: https://files.catbox.moe/qtsa0d.png (~8MB)
