Geez, remember the first “Heavy Metal” movie in 1981? Or the sorta sequel in 2000 starring Julie Strain? Well forgot those, because they’re making another “Heavy Metal”, to be based on the ’70s sci-fi fantasy magazine of the same name. This latest “Metal” animated movie has some big guns behind it, too — namely director David Fincher, who along with 8 (or 9, they still haven’t settled on the total yet) other filmmakers, will be contributing individual segments to the movie, to be produced by Fincher, Kevin Eastman, and Tim Miller. Best news? They’re looking at an R-rated movie.
