Clark: I dunno what the hell's in there, but it's weird and pissed off whatever it is.
[Last line] MacReady: Why don't we just wait here for a while... see what happens.
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 vulnerable out in the open. If it takes us over, then it has no more enemies, nobody left to kill it. And then it's won.
MacReady: First goddamn week of winter.
[Norris' head grows legs and tries to walk away.] Palmer: You gotta be f**king kidding.
Trivia:
The film was originally banned when released in Finland.
The Norwegian camp scenes were actually the charred remains of the American site from the end of the film. Rather than go to the expense of building and burning down another camp, Carpenter re-used the destroyed American camp.
To give the illusion of icy Antarctic conditions, interior sets on the Los Angeles sound stages were refrigerated down to 40°F while it hovered around 90°F outside.
In the scene where Norris' (Charles Hallahan) head separates from his body, special-FX designer Rob Bottin used highly inflammable materials for the construction of interior of the head and neck models. During the shoot John Carpenter decided that, for continuity reasons, they needed some flames around the scene. Without thinking they lit a fire bar and the whole room, which by now was filled with inflammable gasses, caught fire. Nobody got hurt, but the entire special effects model, on which Bottin had worked several months, was destroyed.
Donald Pleasence was the original choice for the character of Blair. Pleasence was unable to perform the role due to a scheduling conflict.
