in 1981 Heavy Metal a Canadian American animated film that not many remember anymore came out. Sex, Drug use, and of course a lot of violence. And then in 2000, Heavy Metal: 2000 came out in limited theaters, not really a shocker that it flopped the way it did. Also Heavy Metal: 2000 only had one nude scene but a crap ton of violence. Who even remembers these two films, if you ask me the first one is the best even though it doesn't have a real story.
