Re-Animator on AllMovie

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.
