Alien
Ripley: Ash, can you hear me? ASH?
Ash: Yes, I can hear you.
Ripley: What was your special order?
Ash: You read it. I thought it was clear.
Ripley: What was it?
Ash: Bring back life form. Priority One. All other priorities rescinded.
Parker: It's the damn company. What about our lives, you son of a bitch?
Ash: I repeat, all other priorities are rescinded.
Ripley: How do we kill it Ash? There got to be a way of killing it, how - HOW do we do it?
Ash: You can't.
Parker: That's bullshit.
Ash: You still don't understand what you're dealing with, do you? Perfect organism. Its structural perfection is matched only by its hostility.
Lambert: You admire it.
Ash: I admire its purity. A survivor... unclouded by conscience, remorse, or delusions of morality.
Parker: Look, I am, I've heard enough of this, and I'm asking you to pull the plug.
Ash: [Ripley goes to disconnect Ash, who interrupts] Last word.
Ripley: What?
Ash: I can't lie to you about your chances, but... you have my sympathies.
Aliens
Newt: We'd better get back, 'cause it'll be dark soon, and they mostly come at night... mostly.
Ripley: They cut the power.
Hudson: What do you mean "THEY cut the power"? How could they cut the power, man? They're animals!
Hudson: Hey Vasquez, have you ever been mistaken for a man?
Vasquez: No, have you?
Hudson: We're on an express elevator to hell - going down!
Newt: My mommy always said there were no monsters - no real ones - but there are, aren't there?
Vasquez: Look, man. I only need to know one thing: where they are.
Drake: Go, Vasquez. Kick ass.
Vasquez: Anytime, anywhere, man!
Hudson: Right, right. Somebody said "alien" she thought they said "illegal alien" and signed up!
Vasquez: f**k you, man!
Hudson: Anytime, anywhere.
Hudson: Oh dear Lord Jesus, this ain't happening, man... This can't be happening, man! This isn't happening!
Ripley: Get away from her, you bitch!
Alien 3
Dillon: You're all gonna die. The only question is how you check out. Do you want it on your feet? Or on your f**kin' knees... begging? I ain't much for begging! Nobody ever gave me nothing! So I say *f**k* that thing! Let's fight it!
Alien Resurrection
Johner: Hey, Vriess, you got a socket wrench? Maybe she just needs an oil change. Can't believe I almost f**ked it.
Vriess: Yeah, like you never f**ked a robot.
