Was just reading about the new HEAVY METAL project (slated for 2012), which will return to the multi-story format of the original feature, and a thought hit me:  There could be a series of animated anthology films based on other magazines of imaginative entertainment.  The three that quickly come to mind could be culled from the pages of the old Warren magazines:  CREEPY, EERIE and VAMPIRELLA.  With so much material, there would be a lot of source material to draw upon, using the title characters as our hosts for each film.  (In the case of Vampirella, one of the tales could even center around her.)
