Whether Don Siegel’s great 1956 film version of Jack Finney’s “Invasion of the Body Snatchers” was really intended as a metaphor about communist infiltration or bourgeois conformity is almost beside the point, it’s about the near impossibility of fighting dehumanizing forces, which can come from anywhere. And so it was with the equally terrific, or maybe even better, 1978 version directed by Phillip Kaufman. The latter film is one of my favorite remakes of a film classic, in that you could watch back to back with the original and have a great night at the movies. The plots might be similar, but they are in no way the same movie at all.

Below are trailers for both. Remember — you’re next!
