Imagine a 12" MacReady, complete with the huge sombrero...! If 'The Thing' is not the best horror movie ever made, it most certainly is the second best. Can't think of an other Horror movie that tops this one. I love Carpenters movies: The Fog, Christine, Halloween, Escape from New York, ... Great!

I always wanted to add this to the 'Bovine-Ox-buster' discussion in the Alien threat, but never got to it for some reason...
