There is also Heavy Metal 2000
The original was cool for its time, and the concepts in it. But, I prefer the 2000 story better.
I also used to subscribe to the magazine for many years.
Both were ambitious experiments in independent animation of their time, and both are charmingly terrible. I can understand why Kevin Eastman would spend the entire 90s publicly worshiping Julie Strain. It's actually a really sweet, artsy, nerdy love story. On the other hand, with HM2K, for years, we were promised an epic animated continuation of Melting Pot, with that distinctively grungy gorgeous Simon Bisley look and Julie Strain's cartoon booty. What we got instead was a sparsely-animated, rust-colored mess, with CG animation shoehorned in that looked terrible even for the time. To say the least, I was disappointed. I haven't seen it in probably fifteen years, but I can't imagine it has aged very well.
