9. Invasion of the Body Snatchers (1978)
The 1956 original used its alien takeover premise as a clear metaphor for McCarthyism and the paranoia of conformity creeping through small-town America. Philip Kaufman's remake kept the same basic concept but updated the anxieties, shifting the commentary toward blind consumerism and the hollow, disconnected nature of modern urban life. The biggest reinvention, though, is the ending, where the original offered a degree of hope, Kaufman's version closes on one of the most gut-punch finales in horror history, leaving audiences with absolutely nowhere to hide. | © United Artists
