This entry from the 1960s nudie cycle is somewhat of an oddity, featuring less nudity than expected, a semi-competent stab at a plot, a strange silent movie whimsy, and some fine black-and-white photography on location in New York City.
The story involves two young roommates trying to make their way in the big city -- one is a fashion model trying to decide whether to model a topless bathing suit, and the other is a nurse at a hospital that inexplicibly has a lot of caged rats hanging around.
First the nurse introduces the model to the swinging life of Camp Sunshine, a nudist colony upstate, then accidentally spills chemicals on the rats, turning them into killers that chase her out a window. Her doctor boss, being the responsible sort he is, disposes of the dangerous chemicals by throwing them into the ocean. The plot just gets more ludicrous from there, culminating in the filmmakers trying to destroy the monster with parachuting scientists, a couple different armies and an entire stock footage library. One of the goofiest things you'll ever see.
The rat attack!
This was the first effort for producer Gene R. Kearney, who went on to a more respectable career as writer and director in television, working on such shows as "Night Gallery," "Kolchak the Night Stalker" and "Lou Grant."
"The Thrill Killers" (1964).
Take a Look:
This purports to be the trailer, although it's just a randomly edited bunch of shots. (Warning: Thar be boobies 'n' booties ahead!):
