FLIGHT TO MARS (1951)

In FLIGHT TO MARS (1951) we take an early trip to Mars, where we find strange pyramid buildings and an advanced civilization. The story is of space ship carrying four scientists and a wisecracking news reporter lands on the planet Mars and discovers signs of an underground civilization. The entrances to the underground world on Mars are small pyramids, but natural resources on Mars are dwindling, and unless the Martians can re-colonize on Earth, their civilization is doomed.
