Thou shall have mechanical problems that are readily solved by “re-routing” the “technobabble”.
OSHA is a thing of the past when working at a starship navigation consule - equivalent to a death sentence. (phaser fire hits the lower decks and the bridge consoles explode sending crewmen flying.)
Thou shall avoid plots dealing with technology, a future society, or any impact of the devices and themes shown. Instead, just make an action or horror movie in space.
Yea verily, ye must have one character who uses technology every day, but still expresses distrust of it because there are things “man was not meant to know.”
All technology, even alien technology, is compatible with eachother. This is particularly evident within the communications system. Some attribute this to the Communication Act of Stardate 11.25.2222222 but others say it is just a plot device
PS, Or perhaps Microsoft really took over the universe. :eep:
Despite the knowledge there is no gravity in space everything and everyone will remain perfectly positioned/seated inside their space ships.
(although Star Wars et al. would be pretty stupid if everyone was floating around, how on earth could they work on those computers?, but Light Saber fights would be pretty gnarly)
Any cute creature, like the “Muffin” of Battlestar Galactica,* can suddenly mutate into a colossal, destructive creature which advances on innocent humans with an insane urge to kill or eat or both.
*Just used as an example of the nature of the creature. So far as I know Muffin did not do this. 
Any rational statement made by a Captain Kirk type to a villain will be interrupted by a loud shout of “silence!” by the villain. (viz: “The Corbomite Maneuver.”)
No routine thing such as cleaning (custodial work), paperwork, or routine discipline is shown, let alone characters dining, using the bathroom :D, or sleeping. Anything and everything that happens is 100% germane to the plot/story line. :rolleyes:
Despite what we understand from Newton’s laws of motion, no gunlike weapon fired in space has a “recoil.”
As partially alluded earlier in this thread, male space people are more fully dressed than female ones; and all women critical to the plot are either beautiful (heroines) or monstrously hideous (villainesses). (And in posters, this is worse still: The poster for the original Star Wars movie showed Carrie Fisher, as Princess Leia, wearing a dress with a long slit up the side.) :eek:
The reason for light travelling slowly and sound propagating through space in the future is obvious. The ether will thicken in the future.
This is why spaceships will be able to make U-turns with ease.
The comet/asteroid on a collision course with Earth shall have a gravitational field strong enough to walk and/or drive a jeep on, even if it’s small enough to fit on Paramount’s LA studio lot.
Haha, Futurama had a bit like that once:
"Silence! You humans have already been found guilty!"
“Silence! The only appropriate punishment is death.”
"Silence! I concur."
oh, and:
Robots think by applying cold, unfeeling logic. When said cold, unfeeling logic leads them to decide that all human characters must immediately be killed, the cold unfeeling robot will start to cackle like a madman.
All spacesuits shall be equipped with bright lights inside the helmets, shining directly onto the wearer’s face, even though, in real life, this would make said wearer unable to see anything but said lights.
There shall be no acne in SF, evev on children, who must be prodiguos in the ways of their father, who is either dececed, evil, or both.
Being in zero gravity will cause people to bob up and down as if they are in water.
People shall suddenly gain telepathy in the future.
Human cleverness can overcome any amount of alien knowledge and technology
Thou shalt have a classical soundtrack
Space must be conquered by western civilization
Space ships should be aerodynamic or at the very least bank like an airplane in order to turn
Above all else, science fiction in the movies must not deal with subject matter not already covered in science fiction literature at least twenty years ago.
Spaceship combat shall require combatants to maneuver within close visual range of each other, indeed often in danger of collision. (This goes back to the problem of slow light in space, since a distant enemy has plenty of time to dodge your lasers.)
Androids shall aspire toward humanity, because it makes sense that a superintelligent, essentially immortal being would want to get fat and die.
No science-fiction film should have a plot that you can’t safely discuss in church.
Clones? Evil.
Future societies should have nothing but words of blistering contempt for every aspect of modern humanity. “Twenty-first century computers? You’d be better off with an abacus!”
For some reason, there are no gay people in the future.
I -know- I posted, but it’s something like an hour later, and it still hasn’t shown up. Let’s try this again…
If you should, for whatever reason, find yourself in an environment, you shall immediatly start moooooooviiiiing veeeeeeeryyyy slooooowwwlyyyyy as a visible cue that you’re weightless (Since floating through the air or walking the walls in magnetic boots is obviously not enough of a giveaway).
No matter how advanced your technology is, the ground forces of the future shall never be as good as even a modern millitary force free of these commandments.
Basic laws of physics, such as ground-pressure, square-cube law, and velocity, shall not apply to any super-weapon type of vehicle. Especially mecha. Bigger is better, end of debate.
Thy main computer shalt be tied into everything on the ship\base\planet right down to the shower controlls with ineffective or non-existant manual overrides so that when the alien\evil program\madman takes over the main computer he controlls everything untill the hero manages to blow up\shut down the main computer with a paper clip.
lasers can be deflected and blocked, but no one thinks back to the “good 'ole days” and reinvents the gun.
When thy ship is hit with the enemy’s phasers, thyself and thy crew shalt assume “blast position” against a railing in the bridge and remain there until the askew camera angle is once again righted.
(Yes yes, this is mainly for TOS, but meh…)
Heck, that commandment applies not only to all fiction, but all storytelling as well!
Travelling through time shall looketh uncannily like either going down a glowing waterslide, or jumping through a portable hole.
