10 Smartest Decisions In Horror Movies
3. Copper Wire - The Thing
From one type of blood test to another, The Thing's assessment of impending doom is far more literal. When a group of Antarctic researchers are attacked and assimilated by a recently defrosted alien, MacReady takes fate into his own hands by tying up the crew and checking their humanity. Slowly working his way through a line of his friends, he takes a blood sample and prods a hot copper wire into it, as the theory is that The Thing taking over their bodies will react and defend itself no matter what form it's in.
Standing by with flamethrowers, MacReady finds one of his team has been infected - and it's not the one he suspected. Either way, it's a genius idea, one that offers a very public outing of any alien pretenders to the whole crew and allows for them to be quickly dispatched of should any anomalies turn up.
The only thing that was overlooked was sticking a bunch of tied up men together in the same room as a hungry alien life form that latches onto any living organism nearby since windows then gets his head turned into cat food. You win some, you lose some, I guess.
