One of the best sci-fi movies ever
I have been fascinated with this movie ever since I saw it over 30 years ago. I consider it to be in the top 5 of sci-fi movies ever made. Why?
-It's a great sci-fi story: A man appears in the desert one day, walking to civilization. In short order he becomes the head of a scientifically advanced corporation. He seems to have a mission to build a spaceship. Is he an alien? We see flashes of a seeming alien culture. Are these his memories? What is his purpose? Although the special effects are not flashy, they are entirely appropriate to adult tone of the movie - they work.
-It's a great mystery: Nothing is explicitly stated, we learn almost everything through inference. Everything is there which you need to know, but you have to pay attention.
-It's a great love story: the Earth girl who falls in love with him is one of the most touching characters I've seen. At the same time attracted to him personally and repelled by his alienness, she retreats into alcoholism at times, but always comes back to her Tommy.
-It's got pathos: the ultimate reason the story works is the main character, Tommy. Played by David Bowie, in the role of a lifetime, the alien character is a man in love who is on a rescue mission to save the one he loves. Trapped in a world of aliens, he struggles mightily to build the spaceship to save his family, but ultimately fails because he is discovered and caught by the government. He is not so alien that he can't relate to human beings: he does have human friends, and even a measure of human love.
