Herbert West (Jeffrey Combs) is a brilliant medical student who has perfected a green-glowing serum for regenerating life into dead things -- or even parts of dead things. But a corrupt superior, Dr. Carl Hill (David Gale), assumes control of West's experiments and winds up, by ghastly necessity, using the stuff on his own severed head and body. West and in-over-his-head co-worker Dan Cain (Bruce Abbott) struggle to control the now out-of-control effects of the serum, but the bone-saws and zombies complicate their plans. Anchor Bay has gone out of their way with this release, delivering a brand new 70-minute featurette as well as multiple audio commentaries, interviews, exhaustive marketing materials, and deleted/extended scenes. The packaging is notable for the regeneration syringe pen, which marks this limited release as the one for collectors to shoot for.
