This movie is so bad, that it's actually somewhat likable.
Mistaken for gods, the men must destroy The Great One or face death, but meanwhile they fall in love.
There they find a primitive society of cave women who routinely sacrifice virgins to appease The Great One, the top dog dinosaur on the the island.
When walking it has movable hips and thin stick arms poking out of round protrusions on its chest, the rest of the time it looks like a normal T-Rex.
This has everything that a bad movie should have, including horrible dialogue, laughable special effects, and women who were cast because of their cup sizes.
Five downed pilots must contend with hungry prehistoric beasts and lusty cave women on a lush island paradise.
