Trash-movie icon Allison Hayes (Zombies of Mora Tau, The Hypnotic Eye) plays the part of an unhappy housewife turned into the title behemoth after an encounter with a bald alien (it’s late, she’s had a couple drinks, she’s alone on a highway . . . you know how these things are). Not as dadaistically awful as one might have wished, though the elephant syringe injection scene makes up for a lot. SF stalwart Nathan Juran (The Deadly Mantis, 20 Million Miles to Earth) directed, with occasional despairing lunges in the general vicinity of style. With Yvette Vickers and William Hudson (1958).
