With a framing story about a glowing green orb claiming to be the embodiment of all evil, the film shuttles through eight episodic tales of sci-fi adventure, each fueled by some of the most wretched rock music to emerge from the 1980s. The most consistent trademark is an abundance of blood-splattering violence and wet-dream sex, the latter involving a succession of huge-breasted babes who shed their clothes at the drop of a G-string. It's all quite fun in its rampantly brainless desire to fuel the young male libido, and for all its incoherence Heavy Metal remains impressive for the ambitious artistry of its individual segments. Courtesy of producer Ivan Reitman (who'd just scored a hit with Stripes), voice talents include several Canadian veterans of Second City comedy, including John Candy, Harold Ramis, Eugene Levy, and Joe Flaherty. --Jeff Shannon
