God damn, loved it. Watched it hundreds of times. The sound track is always rotating through my playlist.
I used to have collections of the original magazines. The magazines had much better art than the movie but the movies adaptation was better in terms of dialogue. For example Den was humorous in the movie but very dark and dramatic in the magazine. But richard corbins art was so much better than anything in the movie.
Always wanted to see a true part 2 based on the 70's stories.
Supposedly Love, Death + Robots was supposed to be Heavy Metal Part 2. LD+H was also very good.
Heavy metal is a staple like Blues brothers, fast times at ridgemont, stripes, caddyshack etc...
Also Lee Haney posed to Heavy Metal by Don Felder for one of his Olympias.
