Aliens
There is literally no competition. Every scene has at least 1 classic line. Aliens is also the gold standard reference used by all action movies since.
It’s a dry heat
Nuke it from orbit
There goes our salvage guys
You got the duty, open that bag
Mostly
Hmm that is more about social conversation. You’d get over it if this was the norm.
Except where actual safety is concerned, all information should be public. That means Individuals, businesses, authorities, governments, etc, should not be able to hold any information privately, it should all be freely available to everyone. There only private information is what you can hold in your head.
Anyone who thinks about this idea for more than 30 seconds decides it is a really bad idea. I honestly believe that true information freedom will also free the human race, and that is the unpopular part. Everyone seemed to think I’m naive but people are just frightened kids and secrets are their first line of defense.
The “Mostly” thing is the most famous quote from Aliens.
The movie quote for “its a dry heat” is from Aliens but I think it is a common phrase used in places like Arizona.
I probably didn’t pick the most well known ones, but watch the film (which is always worth doing) and you’ll see.
“Get away from her you bi tch”
