This cult classic centres on a hormone intended to alter the breeding cycle of rabbits overrunning farmland. Instead, the hormone turns these rabbits into flesh-eating, 150-pound monsters.
Roy Bennett (Stuart Whitman) and his wife Gerry (Janet Leigh) interrupt their studies of bats to investigate odd phenomena in a desert ranching area. Rabbits are overbreeding like crazy, making grief for rancher Cole Hillman (Rory Calhoun).
Unfortunately, the bunny-loving Bennett daughter Amanda (Melanie Fullerton) switches test animals involved in Roy’s genetic experiment and then lets one of them go.
Herds of oversized carnivorous rabbits are soon threatening livestock, ranches and any human they can catch until the scientist solves the problem with a crazy extermination scheme involving high power lines and some railway tracks.
Unfortunately, no matter how you photograph and light groups of bunny rabbits, they look cute, and not in the least bit threatening. Exhibit 1: Wallace and Gromit: The Curse of the Were-Rabbit (2005).
