Leading man Richard Derr is a much sexier version of Danny Kaye.
Leading lady Barbara Rush is the brilliant scientist daughter of her brilliant scientist father. Yet she exhibits the classical female double mating strategy. She's torn --not really-- between The Stable Nice Guy and the Maverick Bad Boy. Guess who wins.
The United Nations exhibits its now legendary uselessness by rejecting the warnings of the brilliant scientist.
The leading man is an American who has decided to live and work in South Africa. No one remarks on the evils of apartheid.
No surprise, really. When the final group of survivors is chosen to board the space ship for the new world, they are monochromatically White.
This is completely unremarked upon. (Now that's what I call cultural self-confidence!)
The Evil Bad Guy is Differently Abled. But he understands human nature far better than the rational and morally upright scientists. And his capitalist money is what funds the project that will save the sons of Adam from extinction, including the humanitarian prigs who find him morally repugnant.
Funny how hard it is for sentimental liberals to keep from subverting their own ideology.
