I saw this film years ago, but can't remember the title. The human race is fighting against aliens. A human soldier crashlands on a planet which seems deserted. He finds another survivor but he is an alien enemy. They come together to survive. The human teaches him english language and the alien teaches him alien words. I remember the alien seemed male but he had a baby. In the end they are great friends it is really moving film about brotherhood. What is the title?
