Almost. A few of them are female, and speak in soprano voices. Many of the baritones also have echo chambers in their larynxs. And virtually all the unfriendly aliens speak in a flat, almost mechanical monotone.
The main piece of safety equipment in a 1950’s spaceship is a baracalounger, which crew members recline during takeoff and landing.
We can’t test nuclear weapons in the ocean because they’ll wake up dinosaurs, we can’t test them in the Arctic because they’ll thaw dinosaurs, and we can’t test them in space because aliens will arrive and bother us. Dammit, where are we supposed to test the things?
In the desert, of course. Although you still have to worry about anyone accidentally exposed to radiation either shrinking incredibly or growing to, say, 50 feet.
Once the radioactive ant/spider/man/woman/gelantinous blob is subdued and safely stored away in a vault/the Arctic the best way to put a bow on the whole experience is to sadly shake one’s head and say “They meddled in God’s domain.”
One thing I learned is that no matter how technologically advanced and overwhelmingly powerful a monster or alien species is, they have a singular fatal vulnerability to something readily available to the good guys.
My favorite scene is the nowadays unintentionally hilarious bit in the old “Day the Earth stood still” when the doctors end examining Klaatu at the hospital:
*"DOCTOR ONE: How old do you think he is?
DOCTOR TWO: Oh, I’d say 35, 38.
DOCTOR ONE: He told me this morning while I was examining him. He’s 78.
DOCTOR TWO: Oh, I don’t believe it.
DOCTOR ONE: Life expectancy is a hundred and thirty.
DOCTOR TWO: Well, how does he explain that?
[Doctors begin to light cigarettes and start smoking in the hospital!]
DOCTOR ONE: He says their medicine is that much more advanced. He was very nice about it, but he made me feel like a third-class witch doctor!"*
Don’t forget that the residence/labs of world reknown physicists can be approached and simply entered by a stranger with a small boy in tow. Heck, you can even mess with their equations on the blackboard instead of leaving a note if they are not at home.
All interstellar starships are shaped like round, basically flat discs that kind of look (from a short distance) like frisbees or the lids to a cooking pot. They also invariably have long antennea attached to them that look like strings extending upwards from them.
The precocious but excitable ten year old boy’s “wild stories” are always on the up & up. Always take very seriously the boy’s ‘unbelievable’ accounts of little green men in the hills just over the ridge.
If somebody you know starts hysterically ranting about their spouse ‘not being their spouse - he/she’s an imposter’, brew a STRONG pot of coffee, stock up on caffeine tablets, and spray pesticide on every last plant on your property.
If you’re standing over the body of an inspector who’s dead, murdered, and somebody’s responsible, it’s quite all right to scratch your temple with your revolver when you do it.
I just remembered one - the first person to see/experience anything unusual or odd (if it isn’t the precocious ten-year old boy that is) will be the town drunk. Most people will just laugh off his eyewitness account, and treat it with the humorous irreverence that alcoholism-induced hallucinations deserves.
