Warning From Space (1956) torrent

UFO's are seen around Tokyo. Because they look like giant starfish the aliens cannot approach us without creating panic. Hence one of them sacrifices itself and takes the form of a popular female singer. It/she warns mankind that a meteor will crash on Earth. While the approaching meteor causes hotter and hotter weather, mankind runs and builds a last-chance anti-meteor weapon.

Yes I know..... quite the costume ;-)
