That we’re the only species in the universe that doesn’t drool.
Movies about childhood sleds need more explosions and boobs.
What, Citizen Kane wasn’t science fiction? It would have been a better movie if it were.
Future Events such as these will affect you, in The Future. (Plan Nine From Outer Space)
That’s good. I’m interested in the future since that is where I’ll be spending the rest of my life.
Speak for yourself! 
I understand the faith thing, but I still think it’s cheating. What if a faithful fence-maker created that picket fence? And with that much faith the candlesticks were perfectly arbitrary. Van Helsing could have held up a telescope and scared Dracula away.
Apparently there were no Black actors in sci-fi in the 50’s. The few that did served as either alien chow or very, very, very minor characters.
Atomic bomb tests will make gila monsters grow to ginormous size, but they won’t eat the giant ants. Hot-rodding teeenagers played by 27 year olds are our only hope against them.
Any time you hear a theremin, it’s time to get the hell outta there.
In space, it’s important to keep your ego in check…but even MORE important to watch your id.
Things generally improve once a scientist takes charge. This holds true even if science is the cause of the original problem.
However, scientists with facial hair never take charge.
Humanity is the only species in the universe that uses contractions.
If a space alien has the ability to speak, it invariably complains a lot.
The brain is the most easily mutated structure in the human body.
All scientists use microscopes.
Radiation is surprisingly creative.
Caves are always bad news.
Animals can hibernate for millions of years.
No species of dinosaur ever really went extinct.
It wasn’t a 1950s movie, either.
General rule: Non-human aliens/mutants only want woment to mate with. There are no bloboids who like guys.
The flip side: Any planet/island of one gender is all female and they only want men.
Well, to be fair, sometimes aliens/mutants want women to eat (in a non-sexual way), especially if they’re bloboids. Then they’ll eat guys just as readily.
Agree with you about the single-sex planets. As I note in mmy post above, there are plenty of awful 50s flicks with sex-starved women and no men. Imagine if a ship full of Earth Women landed there. Or don’t.
No matter how slow the monster is, you will get eaten.
Aliens are all bipedal humanoids who speak perfect American English, in baritone voices.
All nuclear-mutant monsters have an instinctive urge to destroy human cities.
Conventional firearms and military explosives are useless against any of them.
Oh, and all aliens want to kill us, eat us, enslave us, or protect us against self-destruction. None are just exploring the neighborhood and only want to visit and make friends.
WHAT is the name of that flick? I’ve been looking for ages for that one.
It was 1953’s Cat-Women of the Moon. It also featured a comically ridiculous giant moon-spider and Sonny Tufts.
If Frankenstein’s Monster or The Mummy are lurching drunkenly towards me, don’t bother running; no matter how fast or far I run, when I look over my shoulder they’ll still be 10 feet behind me. And then I’ll trip and fall and be killed.
Aside: There’s an excellent deconstruction of this in James Tiptree, Jr.'s short story “Houston, Houston, do you Read?”. For that matter, Tiptree is pretty much the go-to author for gender issues in science fiction, period.
With one shining exception: It Came From Outer Space. In that one, the aliens were just trying to repair their ship and get away from Earth as fast as they could.
