The Thing

   The Thing - in which a bunch of scientists, trapped in Antarctica, are infiltrated by an alien who does a combination of taking over bodies or recreating them with increasing accuracy. So, at first the guys don't know anything is wrong, but they take in a stray dog the Norwegians were trying to shoot from a helicopter, and check out the Swedish camp, which I assume is the only camp in town. The Swedish camp is fucked up and burnt to shit, and in their garage they have a huge block of partially melted ice. Maybe Captain America? Anyway, back at the compound, Kurt Russell and his beard are RJ MacReady, a natural leader and regular badass. He ends up taking charge when they find out there is an alien invasion/infiltration, what happened was they walked into the barn area where the animals were kept and one was being turned into the THING. It is so gross. Then the old guy, Wilford Brimley kinda flips out and they lock him up in this shack that they can only get to during the storm by following this string because of white-out conditions. So, the alien slowly takes over, and MacReady yells at Wilford Brimley for destroying the helicopter, but he was thinking ahead, because the alien can't leave the continent, or it will destroy the world. Like, he's right, but he kinda made a unilateral decision. Whatever, I'm fine with it. So, guys keep getting turned and eaten, and they are carrying flamethrowers to fight IT, so there is this great scene where MacReady and one cowardly guy get the remaining men tied up and test their blood with a hot copper wire, and if the blood reacts, the guy is really THE THING. Its awesome. So, they find out a couple guys are secretly the things and they flame them. Burn them to death. The thing still exists somewhere and keeps trying to get them. It is relentless.
      So, the guys keep getting picked off until there are only MacReady and Childs left. They end up in an adjacent ice cave with all the remaining dynamite, hoping each other are not the thing. I hope so, too. They are trapped in there, and it never stops snowing.
