You know Toei is the studio notorious for making those POWER RANGERS-type shows and anime, created this film to compete with other films such as JAWS (1975), the Dino Delaurentiis KING KONG remake (1976), Britain's LAND THAT TIME FORGOT (1975), AT THE EARTH'S CORE (1976), PEOPLE THAT TIME FORGOT (1977), and Spain's WHERE TIME BEGAN (1976). This one shows a Plesiosaurus and Pterodactyl terroize people and fight against each other. Infamous classic. Suitable for the whole family? You be the judge.
