A landmark in cinema, not just in sci-fi, but in cinema period. This film truly set the bench mark for high tension, suspense, and paranoia which the 1970's remake comes close to, but doesn't quite match. This is the film that introduced the idea of aliens that take over the world via the mind (the idea was first popularized by Robert A. Heinleind in "The Puppet Masters" and later turned in to the book Invasion of the Body Snatchers" by Jack Finney) and has since become a common theme in sci-fi and horror, but anyone who is interested in good films or the roots of sci-fi needs to watch this movie and if you have the time read Heinleind and Finney's novels as well.
I was 10yrs the first time I saw this film. I walked down to Hollywood Video (whom are now bankrupt) which was a few blocks from my house and since I was always attracted to creepy and/or horror movies, I thought this looked very interesting and I rented it. When I got home and watched it I was absolutely amazed at this movie and how terrifying it truly was, as prone to nightmares as I already was, I realize a couple of years back that this movie gave me nightmares for the next 14yrs it affected me that much. I watched it not once, but 10 times over the next week, and soon this movie was tied between The Lion King and itself for my favorite movie of all time.
When I watched the movie as I got older, the feeling of terror, claustrophobia, and paranoia never vanished from this film, it gives that same creepy feeling every time you view it. I am sad to say I can no longer watch it for this very reason, it gives me horrible nightmares, but I enjoy the memory of it and it still remains in the top 5 of what I consider to be the best sci-fi films of all time.
I highly doubt most of you will be as affected by it as I am, but I do hope you all enjoy it.
