Invasion of Astro-Monster

Aliens from Planet X make an irresistible offer to the people of Earth: let them borrow Godzilla and Rodan to help defeat King Ghidorah, and in return they will provide a cure for all known human diseases. But the aliens’ duplicity is soon revealed, as they deploy all three monsters in their quest to conquer Earth. This retro romp, featuring American star Nick Adams, stands as a high point in the Showa Godzilla series.
