I watched the Svengoolie show movie “Tarantula” last night, although I fell asleep for what turns out to have been about 20 minutes or so during the second half hour of this 1955 film about radioactive nutrient producing a giant tarantula. I had to catch up on what I missed on the Internet Archive.
Don’t get me wrong, the movie didn’t put me to sleep; in fact, there were various segments that reminded me of various tangents I’m about to go off on.
Anyway, the film was directed by Jack Arnold and starred John Agar (Dr. Mass Hastings), Mara Corday (Stephanie ‘Steve’ Clayton), and Leo G. Carroll (Prof Gerald Deemer, who I guess was in a lot of Hitchcock films including North by Northwest, which Sena has seen). Raymond Bailey (Townsend, Arizona dept of agriculture scientist) had an interesting line I’ll mention later. Bailey also played the banker Milburn Drysdale in the Beverly Hillbillies TV show in the early ‘60s-early ‘70s.
The short summary of this film is that it’s one of several related to the fear of radioactivity-linked science gone bad leading to the creation of really big bugs running amok in tiny towns in the desert southwest. The main angle here is Prof Deemer’s scientific work on preventing world starvation from overpopulation by creating a nutrient that would, if mixed with the evil radioactive isotope, cause hungry tarantulas to grow to enormous size, in turn leading to cattle mutilations that would prevent long wait times for motorists waiting for cows to cross Route 66, consequently unblocking the path to McDonald’s restaurants, although the food chain interruption from the beef shortage caused by tarantula predation would eventually result in the loss of big macs leading to cannibalism, thereby cancelling world hunger by population reduction.
Scientists never think this one through.
But there are other things to talk about with respect to this movie. One of them is the word “acromegalia.” I know about acromegaly, but the term “acromegalia” was a new one to me, although it turns out to be an old term. Acromegaly is the usual name for the medical condition. Why the writers chose this word is a mystery. Both mean a rare pituitary gland problem which produces too much growth hormone leading to gigantism in which the hands, feet, and face grow bigger.
Another fascinating thing about the film is that I think I can hear Dr. Deemer call the radioisotope a specific name, something that sounds sort of like “ammoniac.” In the internet archive version, see if you can hear it at about 27:47.
Sena can hear it too. But I can’t find any reviewers who mention it and even AI denies that the radioisotope is given a name in the movie. Also, if it was made just for the movie, it doesn’t make sense because most isotopes’ names end in “-ium,” so no made-up word for it should sound like “ammoniac” which makes you think of ammonia, something somebody would wave under your nose to smell if you fainted from the sight of the giant tarantula.
Another interesting thing is the dialogue between Dr. Hastings and an Arizona Agricultural Institute scientist, Dr. Townsend (played by Raymond Bailey). The gist of the interaction is that Dr. Hastings brought a specimen of giant tarantula venom for Dr. Townsend to analyze, but when he says he found giant pools of it, Townsend is incredulous and accuses Hastings of either having a nightmare or being the biggest liar since Baron Munchausen. On the internet archive this exchange happens at about 59:07.
This is priceless. I know about Baron Munchausen because, as a consulting psychiatrist for many years I saw patients who had the syndrome which used to be called Munchausen’s Syndrome (now called Factitious Disorder) which is essentially a mental disorder in which patients claim to have diseases which they don’t actually have but fake them and lie to doctors about it. I gave lectures about the syndrome. There’s a fascinating literature about it and, the odd thing is that the real Baron von Munchhausen was a famous adventurer and raconteur—but he was not a liar.

What many people don’t know is that it was actually a fellow named Rudolf Erich Raspe, a German scientist and scholar who wrote a book about the baron which was mostly made up. Raspe was the liar, not Baron Munchhausen.
A person with Factitious Disorder was hospitalized at University of Iowa Health Care back in the 1950s and a long case report about it was published in the Journal of the American Medical Association (JAMA). Further, a physician named William Bennett Bean, MD in the Department of Medicine at the University of Iowa wrote a very long poem about this which you can access. There was also a fascinating case report published in 1980 in the New England Journal of Medicine (NEJM) by medicine residents claiming they had seen a patient who lied about having Factitious Disorder (Factitious Munchausen’s Syndrome). The residents later admitted that they made up the story. I summarized most of this in a blog post a few years ago.
Finally, there is a line by Dr. Hastings at about 1:04:45 which reminded me of a Verizon commercial years ago: “Can you hear me now?”
I think that’s more than enough about this movie, which I would give a rating of 4/5 mainly because it evoked so much from the deep recesses of my memory.

Addendum: I couldn’t shake an urge to comment on a gesture of earlobe tugging that Dr. Matt Hastings engaged in while asking Prof Deemer about how quickly Jacobs developed his physical malformations. You can find this on the Internet Archive at time 28:36. Deemer dismisses it as acromegalia and nothing more but finally suggests Hastings could see that an autopsy be performed on Jacobs. I suspect Hasting’s earlobe tug might be dismissed as simple overacting, but there could be other interpretations.
