Ghidorah, the Three-Headed Monster - Ishirō Honda

A princess from a small Himalayan country becomes possessed by the spirit of a Venusian (a Martian in the American version) and escapes a plane just as it explodes. As this happens a meteorite falls from the sky containing Ghidorah, the monster responsible for her planet's destruction. At the same time, Godzilla and Rodan emerge from hibernation and not only attack Japan, but each other as well. Mothra, along with its twin priestesses, attempt to convince Godzilla and Rodan to stop their fighting each other and to team up to fight the new monster. At the same time, the princess is being hunted by a group of assassins who want to kill her so that her enemies can take over her homeland.
