Put your hands up if you got home from school everyday and watched this. Sometime in the late 70's, early 80's I think it was. Well, it's back as a movie. AWESOME. And I found a company that does miniatures.
Some editional information about the plot for those who did not have a TV in their house
"In the distant future, the war between the human race and the Gamilon has taken its toll on the planet Earth. Constant bombardment of radioactive asteroids has rendered the planet's atmosphere uninhabitable. As a means of relief aid, Queen Starsha of the planet Iscandar offers the Earth Forces a device that can completely neutalize the radiation off the planet. For this task, the space battleship Yamato is launched from the remains of its World War II ancestor on a 148,000 light-year journey. However, the crew of the Yamato has only one Earth year to travel to Iscandar and back, or the human race will come to an end".
