'Invasion Of The Body Snatcher's is my favourite 1950s science fiction movie alongside 'Forbidden Planet'. Both are very different movies. 'Forbidden Planet' is arguably the first SF blockbuster, an intergalactic adventure, in colour, with a large budget and impressive special effects. 'Invasion Of The Body Snatcher's is a smaller movie, a low budget black and white paranoid thriller that is a classic of its type. Many subsequent movies have been influenced by this one, and there have been at least two remakes (Philip Kaufman, Abel Ferrara), but it still takes some beating! Director Don Siegel is best known for tough guy crime dramas like 'The Killers' and 'Dirty Harry', but shows his versatility with this extremely effective and disturbing horror story. The legendary Sam Peckinpah had an uncredited hand in the script, and (keep an eye open for) a small cameo as a meter reader. Kevin McCarthy is terrific as the small town doctor turned hero. His performance is excellent, and made him a legend to SF and horror fans everywhere (he reprises it briefly in Kaufman's excellent 1970s remake by the way). The lovely Dana Wynter leads a strong supporting cast, and buffs will get a particular kick out of seeing Carolyn Jones (a.k.a. Morticia Addams) and Whit Bissell. ('I Was A Teenage Werewolf', 'Creature From The Black Lagoon' and too many others to mention!) This movie has aged very well, much better than say, 'The Thing From Another World', and still stands as THE 1950s paranoid SF/horror movie. An absolute classic that I guarantee still packs a punch! Highly recommended!
