-Millenium Actress
-Ghost in the Shell
-Akira
-Ninja Scroll
-Macross Plus (I know, I know -- technically it's considered an OVA in it's 4-episode version, but we'll just reference the movie cut for the sake of compliance.)
-Anything Miyazaki
-Vampire Hunter D (it holds a special place as the first real adult-oriented anime flick I ever watched.)
-Call of the Wild (animated version originally released by Toei around '81, adapted to English by Harmony Gold with later editions released by Vestron, GoodTimes Video, etc. -- I loved this movie when I was little, and still have it to this day. I never really considered it "anime" until I grew a little older and more aware of the style. An excellent watch if you can get hold of a copy.)
