Night of the Lepus (1972) starring Stuart Whitman, Janet Leigh, Rory Calhoun, DeForest Kelley

There was no limit to the cheesiness in the Night Of The Lepus! A hormone intended to alter the breeding cycle of rabbits overrunning Arizona ranch lands instead turns them into flesh-eating, 150-pound monsters! Stuart Whitman (Eaten Alive), Janet Leigh (Psycho), Rory Calhoun (Motel Hell) and DeForest Kelley (Star Trek) are among the intrepid humans facing off against the behemoth bunnies.
