I'd love a Heavy Metal movie that was live-action. Not a remake, mind you, but an original idea.
I had a loose idea for one. Evil people are the hero(es) of the story. The good guys, stereotypically white clothed and things, are the villains. I know this sounds like a villain story, but the evil-doers are necessary and realize that they must win to have balance. It's a bit Darkside of The Force, I realize, but the evil orb in the original could be the McGuffin of the film in this live-action sequel(?) and our lead is of course female, to follow tradition. She's just full on metal. Sword & Sorcery scifi epic. Could be so fun.
