INVASION OF THE ASTRO MONSTERS (1966) (CLASSIC MEDIA)

American  Nick Adams stars in this great Japanese monster bash starring the always sexy Kumi Mizuno. This story revolves around a mysterious planet whose inhabitants trick the earth into giving them Godzilla and Rodan in order to help destroy Ghidrah.
The aliens actually intend to use all the monsters in an attempt to take over the earth. This is an excellent example of Japanese monster movie fun.
The battles between the three monsters is classic and Godzilla even does a "jig" and gives us his best George Forman when fighting Ghidrah.
The aliens are bad from the very beginning and you just know they are up to no good. Highly Recommended entertainment from Japan.
