Mines from forrest gump.
"Private gump, why did you assemble your gun so fast? I did it because you told me drill sargeNT!"

Also another one in full metal jacket

"Private Pyle, you can suck a golf ball through a garden hose"

:-) :-) :-) :-) :-) :-)

"Look at it as on the job training"..
Robert Redford in A Bridge to Far, just before the assault boat crossing of the river Waal, by Nijmegen

OK all you guys..im gonna put some romance in here.

Julia Roberts says to Hugh Grant in Notting Hill

"I'm just a girl, standing in front of a boy, asking him to love her"..

Gotta love this line.
Mary

"Luke i am your father"
classic, never saw that coming.

Too many movies, too many lines.

Young Frankenstein

Igor: (in a Groucho Marx accent) You take the blond and I'll take the one in the turban.

Not a one liner but:

Frankenstein: (speaking of the door knockers) What knockers.
Terri Garr: (speaking of something else) Why, thank you very much.

Kelly's Heroes (possibly the best source of one liners ever)

Oddball: To a New Yorker like you a hero is some kind of weird sandwich, not some nut who takes on three tigers.

Kelly: That's PAINT!

Moriarty: Listen, I've been thinking nothing but good thoughts about that bridge.

Crap-game: Make a deal deal. Maybe he's a Republican. (non Americans might not get that one as well.)

Animal House

Bluto: Was it over when the Germans bombed Pearl Harbor?

Monty Python and the Holy Grail

What is the airborne velocity of a laden sparrow?

Monthy Python Life of Brian

" He's not the Messia, he's a naughty boy.."

From "Tango & Cash" when they're comparing weapons:
Cash:" How come your's is bigger than mine?"
Tango: "Genetics"

From "Hear no evil, see no evil" when deaf Gene Wider stations blind Richard Pryor as a lookout:
"Let me know if anybody comes down the hall"

Can't recall the movie, but the line was great. The lady cop levels her gun and says: "Blink and you'll die in the dark".

Art

How about from Holy Grail?

"I'm not dying, I'm getting better."



In my own particular idiom
Steve

Now Bring Us A Shrubbery! A nice one but not too expensive.

"Go Ahead - Make my Day" - Dirty Harry
"On my command - unleash hell!" - Gladiator
"Custer was a P*ssy" - We Were Soldiers
"Mummies - I hate these guys" - The Mummy
"Fill yer hands, you son of a b*tch" - True Grit

Big Chris at the end of, lock stock and two smoking barrels..
Might not be so well known in the USA..

Ola Nice topic

From the movie Oh Brother Where Art thou:
"You Guys are dumber then a bag o Hammers"

From Boondock Saints:
"Charles Bronson always has a rope"

Check the movie boondock saints probably a top source for good movie quotes and oneliners.

From Dodgeball:
"You would not even hit water when you fall out a boat"

I can name dozens and dozens I really like but these three just sprung my mind

But African swallows are nonmigratory.

Cary Grant in 'Arsenic & Old Lace'

"Does insanity run in my family? It practically gallops"

Vinnie

I have to go with BrandydogUK - the Michael Cain quote from 'The Italian Job'. If anyone in our household sees a wreck - out it comes " You're only supposed to blow the bloody doors off!'

This is one of the all time movies made and my favorite. Here is just one of the many one liners, see if you can guess which movie

hey boys look what I got here
"hey...where's all the white woman at"

My favourite "film" quote is actually from the TV version of M.A.S.H.

Corporal Klinger: "If my dog had a face like yours, I'd shave its butt and teach it to walk backwards!"

But, from a truly movie point of view, a quote that all Staff can relate to...

"After all... tomorrow IS another day!"

All the best

Rowan

Best one!
Everyone should know this one!

Fight me!
I cut your bloody arm off!
"Nothing but a near Flesh wound"

Joe,
"Blazing Saddles." Too many great quotes.
"Man who drinks like that and don't eat is gonna die."
"When?"

Shaun

Oh, my fave, that hasn't been mentioned, "I'm not even supposed to be here today." from "clerks"

Shaun

The best one liner is most certainly from ‘Gone with the Wind’: "Frankly, my dear, I don't give a damn."

A bit of Trivia; according to the ‘Hays Office code’, this was considered swearing and Selznick (Producer) was allegedly fined $5,000 for including the word.

Rowan ye old softie, that is the final line from ‘Gone with the Wind’:
“...Tara! Home, I'll go home and I'll think of some way to get him back! After all, tomorrow is another day!”


Others, I quite enjoy are:

From ‘Rambo II (First Blood Part II)’ “... one more thing, what you choose to call hell, he calls home."

From ‘Saving Private Ryan’; “Earn this, earn it.”

From ‘Cross of Iron’; "Follow me, I’ll show you where Iron Crosses grow."

6th sense:
"I see dead people!"

Pulp Fiction:

"and you should know, I am the lord!!"

now you got all these Arnie quotes that should be read with a strong Austrian accent:

"I'll be back"

"Get Down!"

"Give those people air!!"

"Talk to the hand"

Full Metal Jacket. this movie is a 2 hour quote fest :-) :

"want some ARVN Rifles? never been fired only dropped once"

"I really wanted to see the world, visit exotic places, meet exotic people and, you know, kill them".

"seen any action?" "oh yeah, I seen it on TV"

sorry if I didnt accuratly quoted the lines.
beside that I'd really like to backup what has been said and recommend watching Lock Stock and Two Smoking Barrels (Vinnie Jones is the man!) and Boondock Saints.

Sean Connery as Urquhart in ABtF, upon being told that no radio contact is possible with anybody :
'Most unsatisfactory..'

ABtF

Micheal Caine, as Lt.Col. Vandeleur, at the jump off :
'No rush. We are the cavalry, we shall arrive just in the nick of time.It would be bad form to arrive to early..'

"I fart in your general direction!"
"I'm a zit, get it?"
When told it was a good morning, SgtMj Plumbly Replies:
"What are you now, the F***ing weatherman?"
"NI!"
"No bastard ever won a war by dying for his country. He won it by making the other poor dumb bastard die for his country"
"Use the force, Luke"

oops, i forgot one....

"I'm getting to old for this S***!"
