This movie was almost certainly inspired by the McCarthian communist "witch hunts" of the 1950's.The choice of title for this movie certainly does not do the film justice,which is probably why the film isn't thought of as being in the same league as"Invaders from Mars" and "Invasion of the Body Snatchers",another two films which develop the theme of this hidden "enemy within".Althougth, in my opinion, not as good as those films,it is still,nevertheless,worth adding to the collection of any sci-fi film fan. I do feel that this was one of Gloria Talbot's better film roles.The plot unfolds fairly evenly,with Tom Tyron body being taken over by an alien in the first few scenes.What gradually follows is the actual extent of the alien takeover and their intentions.This movie is available on DVD.
