Ok this movie is definitely sci-horror, the premise to my knowledge had to do with a monster or virus on a spaceship that slowly kills everybody it is graphic in nature. It is not that episode of gal force or they were 11 I have both and love them but its along those lines and feel.

The Alien series maybe w/ Sigourney Weaver?? That was in the 80's

I believe your talking about Heavy Metal.(the movie, not the series which I believe is completely different)
