‘‘What a lovely singing voice you must have.’’ 
Shooter- You’re in big trouble though, pal. I eat pieces of shit like you for breakfast!
Happy- You eat pieces of shit for breakfast!?

The fact that the OP lead with a Star Trek quote brought to mind (one of) my favorite movies quotes of all time:
(Star Trek IV)
And it’s hard to work this one into conversation, but it’s so freakin’ cool.
Apollo 13. James Lovell’s mother, whom everybody has been tip-toeing around to avoid upsetting her:
IIRC, Ebert opined that Gladiator would’ve been fantastic if they’d ended it right after our palm-the-arrowhead hero makes Commodus go pale and shivery:
. . . if you imagine him stabbing the guy in the jugular right then, before smiling while getting cut to ribbons or something, the line is simply perfect.
If you instead continue the movie for another hour, it’s merely memorable.
New scene.
Jerry and Cheryl are at the coffee shop.
Cheryl: I actually have a friend in the Immigration Department who owes me a
big favor. You’re very lucky.
Jerry (somber): That’s wonderful news. Thank you.
Cheryl: You’re a very serious person, aren’t you?
Jerry: Well, with so many people in the world deprived and unhappy, it doesn’t
seem like it would be fair to be cheerful.
Cheryl: I understand.
Jerry reaches for the milk for his coffee.
Cheryl: I think it’s curdled.
Jerry: I don’t care.
Cheryl: Do you ever laugh?
Jerry: Not really. Sometimes, when I’m in the tub.
Cheryl: That’s so sad. What do you do?
Jerry: I’m a comedian. Oh, let me get that. (reaching for the check) You’ve
been so helpful…
“My father says that almost the whole world is asleep. Everybody you know. Everybody you see. Everybody you talk to. He says that only a few people are awake, and they live in a state of constant, total amazement.”
Patricia, Joe vs the Volcano
Mongol: Conan! What is best in life?
Conan: To crush your enemies, see them driven before you, and to hear the lamentation of their women.
Sheldon: You were involved in the Bay of Pigs?
Vince Ricardo: Involved? That was my idea.
Thank you, my friend, finally something that describes how I feel…
It’s a draw. I mean, it shouldn’t happen to a dog. I mean, the situation is hopeless, but not serious. -Otto in One, Two, Three
“Major Strasser has been shot! …Round up the usual suspects.”
or perhaps
“Y’know, Louie, I think this is the beginning of a beautiful friendship.”
or maybe
…well, actually, the whole darn movie is full of great quotes:D:D:D
*'I **am *big. It’s the pictures that got small. ’ Norma Desmond, Sunset Boulevard.
“I’m gonna make him an offer he can’t refuse.”
“If I didn’t have puke breath, I’d kiss you.”
“GET TO THA CHOPPAH!!” - Predator
+1 to many, especially the Josey Wales quotes
WINDMILLS DO NOT WORK THAT WAY!!! GOOD NIGHT!!!
Like the Ghostbusters quote(s) – esp. “there is only Zool”
“You know what kind of people they are. They’re gonna strip you naked and go to work on you with a pair of pliers and a blowtorch.” – Charley Varrick. I know a lot of geeks probably went to work on PFiction and sniffed it out, but it’s much more menacing in the classic Don Siegel movie.
“Gozer the Traveler. He will come in one of the pre-chosen forms. During the rectification of the Vuldrini, the traveler came as a large and moving Torg! Then, during the third reconciliation of the last of the McKetrick supplicants, they chose a new form for him: that of a giant Slor! Many Shuvs and Zuuls knew what it was to be roasted in the depths of the Slor that day, I can tell you!”
