It's a goofy guilty-pleasure pre-MTV sort of thing : ) https://en.wikipedia.org/wiki/Heavy_Metal_(film) (Like the magazine, it's cartoons but not really for kids due to nudity/violence etc.) Rife with cut-corners/executive meddling/production hell issues. Most of my love for this movie comes from the intent of the artists and the care they put into it, despite the cost-cutting "efforts" and other silliness imposed by the Embezzlement Specialists at the movie studio.

I was a big fan of the magazine before the movie came out (it was the precursor to the modern graphic-novel stuff like "V For Vendetta" etc.) Although Heavy Metal (the magazine) has been very influential on many movies (if not outright ripped-off-from,) few writers/directors give proper credit to the source of their plagiarisms.

>Bonus moar fun with that:

Frequent contributor Moebius did the cover art for a French release of "Are You Experienced" and "Axis Bold As Love," the Jimi Hendrix albums. Here's some of his Jimi Hendrix art, putting Jimi into the alien-desert landscapes typical of Moebius' work.
