A Nice Sci Fi Movie of the Fifties
20 April 1999 | by See all my reviews

"This Island Earth" is not the greatest science fiction movie of all time, but it deserves more respect than it is often granted. The boys at MST3K (whom I think are great) may have done this film a great disservice. In its day, it was thoughtful, imaginative, and the special effects were excellent. I disagree with those who say there is no plot. The cold war fears and xenophobia were once again at the center of this fifties effort. The alien as our "friend" was later used in many settings, including one of the best of the "Twilight Zone" episodes, "To Serve Man."

I was young when I first saw this in a movie theater, but even then I found the home planet, Metaluma, very striking and its fate frightening. I fear that often our smugness in criticizing older films, judging them by standards that they could not have hoped to approach because of the limitations of the technology, keeps us from acceptance of their good points and their contributions. I have an acquaintance who can't watch the Maltese Falcon because it is in black and white. What a loss. The sets are striking in this film. The aliens are a bit of a stretch, but I still like what they are. I saw this movie a couple times in a theatre (not the MST version). As people left they were captivated and involved. When we left, we had had fun (not from ridiculing but enjoying). Granted there are no computer morphs and no giant metal bugs sucking brains out, but it is still good stuff.
