The Day the Earth Stood Still (1951)
The Day the Earth Stood Still is perhaps my all time favorite science fiction movie. I must have been 9 or 10 years old when I first watched the movie. I have watched it several times since then. Having a fondness for old black and white movies. I like to categorize black and white science fiction movies as Sci Fi Noir.
An alien (Klaatu) with his mighty robot (Gort) land their spacecraft on Cold War-era Earth just after the end of World War II. They bring an important message to the planet that Klaatu wishes to tell to representatives of all nations. However, communication turns out to be difficult, so, after learning something about the natives, Klaatu decides on an alternative approach.

The remake of the 1951 hit movie The Day the Earth Stood Still has a message about Global Warming.The premise of the movie changed. The threat of nuclear war was the message in 1951.
I prefer the original 1951 movie over the 2008 version perhaps because it reminds me of my childhood. I have some very fond memories from that period of my life. Science fiction movies have been part of my life for many years.
