Za taigâsu: Sekai wa bokura o matteiru

The Andromeda Aliens' flying saucer is the Planet X (Xilian) Saucer from La invasión de los astromonstruos (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 Los monstruos invaden la Tierra (1968) (released later the same year).
