Whats the most quotable movie?

The Princess Bride!
Any other answer is... inconceivable

Monty Python Quest for the holy grail.
Every character, every scene
- I think this is the correct answer, at least in English language.
  From the top of my head in roughly the right order:
  Tis but a flesh wound You're father smells of elderberries We want...a shrubbery Watery tarts throwing swords at people is no basis for a government She turned me into a newt On second thoughts, it's a silly place Bravely bravely ran away You have to know these things when you're a king you know
  
  Off, bad editing
- I thought the last scene was a bit of a cop out.
- It took growing up to get it, but I love the scene where the peasant is explaining to King Arthur that strange women lying in ponds distributing swords is a terrible basis for a system of governance.
- I was going to say Life of Brian, also extremely quotable
- This was my first thought as well
- We found them
  
  That's Empire Strikes Back.
- Never seen it

Monty Python and the Holy Grail
- Now, you listen here: 'e's not the Messiah, 'e's a very naughty boy! Now go away!
  
  Lovely troll!
- Ni!
  
  Oh, what sad times are these when passing ruffians can say "Ni" at will to old ladies.

That would be the 1985 master piece Clue
- Communism is just a red herring!
  
  I'm going home to sleep with my wife!
  
  Lot of red flags
- Are you trying to make me look stupid in front of the other guests?!
  You don't need any help from me, sir.
  That's right! ...
- To make a long story short...
  Too late
- Replying to myself to give The Sopranos an honorable mention!
- Flames! Flames on the side of my face!

Airplane.
- "Surely you can't be serious."
  
  I am serious, and don’t call me Shirley.
- When Kramer hears about this, the shits gonna hit the fan.
- What is it?
  
  It's a vehicle with wings large enough that it can fly, but that's not important right now.
- The hospital? What is it?
- What's the clearance Clarence?
- I picked the wrong day to stop sniffing glue.
- That's an entirely different situation all together now.

Spaceballs?!?!
- Definitely! “Now Lonestar you see why evil will always triumph…because good is dumb.”
  
  Say goodbye to your two best friends. And I don’t mean the idiots in the winnebago.
- Everything Mel Brooks.
  Airplane!
  The Producers
  Blazing Saddles... etc.
  So many of his movies have such memorable lines and jokes that still hold up today.
  
  It's good to be the king.
- This is the proper answer.
  "Would I lie??"
- Comb the area!

The Princess bride, no question!
- Inconceivable!

Oh I'm sorry, did I break your concentration?
Aw man, I shot Marvin in the face.
You know what they call a quarter pounder in Paris?
And you will know that I am the Lord when I lay my vengeance upon you.
- They call it a Royale with cheese.
  Say "what" again! I dare you, I DOUBLE DARE YOU.
  
  What ain’t no country I ever heard of, they speak English in what?
  Naw man, I’m pretty fucking far from ok

Hot Fuzz. Hands down.
Everyone's got guns round here. Like who? Farmers, Farmers mums.
- Hot fuzz for sure, I'm constantly quoting it
- You've got a mustache

Ghostbusters:
Back off man - I’m a scientist
Listen! You smell something?
What about the Twinkie?
Human sacrifice, dogs and cats living together... mass hysteria!
Yes it’s true, this man has no dick
Ok, so… she’s a dog
When someone asks you if you’re a god, you say yes!
Aim for the flat top!
Cross the streams
…and much much more
- 'Get her!'--that was your whole plan?
  
  Janine, someone with your qualifications would have no trouble finding a top-flight job in either the food service or housekeeping industries.
- I collect spores, mold, and fungus.
  
  We came, we saw, we kicked its ass!
- Yeah I'll go along with that.
  
  If there’s a steady paycheck in it, I’ll believe anything you say

Also, dude, Chinaman is not the preferred nomenclature. Asian-American, please.
I'm not talking about the guys who built the fucking railroad here.
- That rug really brought the room together.
  I see you’re not a golfer.
  Mind if a do a J?
  
  You can guess what happens next?
  He fixed the cable?
- Is there really a line which isn't quotable in this movie?

The Big Lewosky
- Well that's just like, your opinion, man.
  
  Far out.
- Nobody fucks with the Jesus
- Where's the money, lebowski?
  It's down there somewhere. Let me take another look.

Kung Pow Enter the fist.
My nipples look like milk duds
- That's a lot of nuts!
  
  That'll be four bucks baby! You want fries with that!?
- Wii U! Wii U! Wii U! Wii!
- Taco Bell, taco Bell, product placement, for taco Bell
- Leap that wall, if you're so great
- Ahhh! My wound!
  It's for the both of us.

Galaxy Quest
- LOL. "Let's get out of here before one of those things gets Guy." Cracks me up every time.
  
  Miners not minors!
- Yes.
  
  DIGITIZE ME FRED

I have several ol' reliables:
Grandma's Boy: "high score? What's that mean?"
Snatch: "when you're in reverse, things tend to come from behind ya."
Tombstone: "i got two guns, one for each of ya."
Big Lebowski: "he's a good man Jeffrey. And thorough."
There's more, but those are probably my most quoted.

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
- Game over man, game over!
  
  Fuckin' aye
- The top two are obviously familiar, but certainly wouldn't attribute the first one to that movie. I don't think I've ever heard the next two phrases used or remember them from the movie, and never heard anyone use 'mostly' as a reference from that movie.
  Maybe it's an insider thing
  
  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"
  
  The "dry heat" line comes from Hudson when they first go into the reactor/nest and they're looking around, just before the attack.

Super Troopers
From "The Snozzberries taste like Snozzberries!" to "BEARFUCKER! DO YOU NEED ASSISTANCE?!" almost every line in that movie is quotable and relevant to most situations.

Blues Brothers
Any Mel Brooks movie
- It's 106 miles to Chicago, we've got a full tank of gas, half a pack of cigarettes, it's dark and we're wearing sunglasses.
  
  Hit it.

Old School and Office Space
- No. No, man. Shit, no, man. I believe you'd get your ass kicked sayin' something like that, man.
  
  Sounds like someone has the case of the mondays.

Anchorman
- I quoted this a lot as a teen!

Star Wars
Any of them (except maybe the sequels)
- Not even close.
  
  You underestimate my power

In French it s between Astérix mission Cleopatre and la cité de la peur
- the former also in Polish
  
  Oh really ? That's amazing :D

In Bruges
Snatch

Lord of the rings
- Well that’s just, like, your opinion, man.

That's a beautiful accent you have. New Jersey?

A lot of quotes from the Batman Dark Knight have become pretty common lingo or at least widely recognized, like "not the hero we deserve but the one we need" or "you either die a hero or live long enough to see yourself become the villain" or even "some people just want to watch the world burn" or "it's not about the money, it's about sending a message", maybe also popularizing the whole "immovable object vs unstoppable force" etc.

Office space
- There's a throwaway line that one of the Bobs says talking with management about the layoffs where he starts with "well just a second there professor" and it's one I never hear quoted but for some reason that phrase gets me every time I watch it.

Ghostbusters.
- Yes, it's true. This man has no dick.
  
  Well, that's what I heard!

Borat

Dumb and Dumber for sure.
https://youtu.be/SOdxz77-lag
- Big gulps huh? Well, see ya later!
- Samsonite! I was way off.
  
  So you're saying there's a chance!?
- Look at the buns on that one... He must work out.

Mean girls

I seem to quote ‘Zoolander’ a lot
- He's so hot right now
- It’s in the computer!

Billy Madison
No milk will ever be our milk.
If peeing your pants is cool then consider me Miles Davis!
He called the shit poop!
What you've just said is one of the most insanely idiotic things I have ever heard. At no point in your rambling, incoherent response were you even close to anything that could be considered a rational thought. Everyone in this room is now dumber for having listened to it. I award you no points, and may God have mercy on your soul.
- It was that damn Sasquatch!

Army of Darkness. I mean it’s freaking Bruce Campbell. Kiss the king baby.
- This. Is. My. BOOM STICK!
  
  Ya GOT THAT!?
- Groovy.

Penguins (of Madagascar): The Movie

Airplane (Flying High)
Bill and Ted’s Excellent Adventure
The Empire Strikes Back

kung pow for sure
- Chosimba, you must take your place in the great circle of…. Stuff.
  
  this is CNN... c.. n... n....

Withnail and I

Star Wars.
- Not even close.
  
  I recently rewatched the prequels with a friend and we quickly decided to count the number of scenes/lines that are used as memes and reactions.
  Don't remember of the top of my head, but it was in the triple digits.
  Star Wars is absolutely quotable on a minute by minute basis - if you like the meme culture around it : ^)
  
  At this point, it's easier to count the prequel lines that haven't become memes.
