I just watched this last night on TCM. I had seen it before but I love this movie. Forbidden Planet was the first science fiction film that was set entirely in deep space, away from the planet Earth. It is considered one of the great science fiction films of the 1950s, a precursor of what was to come for the science fiction film genre in the decades that followed. It is funny how the story plays out when these space explores land and start to explore. I love the sounds of space that you hear throughout the movie.
Anyways here is a trailer of the movie.
