Za taigâsu: Sekai wa bokura o matteiru

The Andromeda Aliens' flying saucer is the Planet X (Xilian) Saucer from L'invasione degli astromostri (1965), the outer centerpiece painted with dark psychedelic colors. One of the machines inside the saucer would later become the Kilaaks' monster control machine from Gli eredi di King Kong (1968) (released later the same year).
