It depends how you want to approach things. If you completely exclude Japanese productions, then, yes, there don't seem to be many SF-orientated animated features.A further couple off the top of my head:Time Masters: often mistaken for an anime, this was actually a French production. May have been seen on BBC2.Heavy Metal: American production based on comic strips that appeared in the magazine of the same name. Different, but always struck me as being rather crude.G.I. Joe: The Movie. In fact there were a couple, some more SF than others, but there was only one actually called The Movie.If you include Japan, however, the list goes on for quite some time: Macross, Do You Remember Love?, Nausicaa of the Valley of Wind, Laputa: The Castle in the Sky, My Youth in Arcadia, no less than 5 Urusei Yatsura films, Gundam RX-93: Chars Counterattack, Galaxy Express 999... and thats only a fraction!
