Fuchs: [whispering] I have to talk to you. MacReady: I'm tired of talkin', Fuchs. I just wanna get up to my shack and get drunk. Fuchs: Mac, it's important. MacReady: What is it? Fuchs: Outside. MacReady: It's 40 below zero outside.
Windows: You guys gonna listen to Garry? You gonna let him give the orders? I mean, he could BE one of those THINGS!
MacReady: [Holding TNT in one hand, and a lit flare in the other] Anybody touches me, and we go.
Fuchs: There's something wrong with Blair. He's locked himself in his room and he won't answer the door, so I took one of his notebooks from the lab. MacReady: Yeah? Fuchs: Listen: "It could have imitated a million life-forms on a million planets. It...
Dr. Blair: Clark? Clark: Yeah? Dr. Blair: Did you notice anything strange about the dog? Anything at all? Clark: Strange? No. Dr. Blair: What was the dog doing in the rec room? Clark: I don't know. It's just wondering around camp all day. Dr. Blair: ...
MacReady: Blair... he got back inside and blew the generator. In six hours, it'll be 100 below in here! Garry: Well, that's suicide! MacReady: Not for that Thing. It wants to freeze now. It knows it's got no way out of here. It just wants to go to sl...
MacReady: I know I'm human. And if you were all these things, then you'd just attack me right now, so some of you are still human. This thing doesn't want to show itself, it wants to hide inside an imitation. It'll fight if it has to, but it's vulner...
MacReady: How you doin', old boy? Dr. Blair: I don't know who to trust. MacReady: [swallows, sighs] I know what you mean, Blair. Trust's a tough thing to come by these days. Tell you what - why don't you just trust in the Lord?
Palmer: I was wonderin' when El Capitan was gonna get a chance to use his popgun.
Garry: [as to MacReady's blood test... ] This is pure nonsense. Doesn't prove a thing. MacReady: I thought you'd feel that way, Garry. You were the only one who could've got to that blood. We'll do you last.
Garry: You reach anybody, yet? Windows: Reach anybody? We're a thousand miles from nowhere, man, and it's gonna get a hell of a lot worse before it gets any better!
Palmer: [arguing about letting MacReady back inside] Let's open the door. Childs: Hell no! Windows: Do you think he's changed into one of those Things? Palmer: He's had plenty of time. Childs: Nothing human could have made with back here through this...
Palmer: [forced at gunpoint to tie up the corpses of Clark and Dr. Copper] This is bullshit, Mac! MacReady: Finish it, Palmer. Palmer: They're dead, Mac!
George Bennings: [Bennings rushes into Childs room] Childs, Mac wants the flamethrower! Childs: Mac wants the what? George Bennings: That's what he said. Now move! Childs: [Childs tucks in his shirts and grumbles] Damn it!
[Holding the others at bay with a flamethrower, MacReady tosses a coil of rope amongst them] Clark: What have you got in mind, MacReady? MacReady: A little test. Windows, you and Palmer tie everybody down real tight. Childs: What for? MacReady: For y...
Childs: He ain't tyin' ME up. MacReady: Then I'll have to kill you, Childs. Childs: Then kill me.
MacReady: Childs, we're goin' out to give Blair the test. If he tries to make it back here and we're not with him... burn him.
MacReady: [holding dynamite] Anyone messes with me... and the whole camp goes! Palmer: Don't argue with him!
