Kenneth Crane followed his classic 'Half Human' with this little masterpiece whose 1956 copyright date indicates they weren't in a great hurry to release it.

In order to reassure the viewer that this is a twentieth-century sci-fi movie we get the usual footage under the opening credits of a wartime V-2 taking off masquerading as Dr. Quant Bradley's "experimental rocket". This time the film being cannibalised is 'Stanley and Livingstone', so they all don 19th Century pith helmets and WALK 400 miles across Africa to the Hollywood Hills to confront the giant mutant wasps following the "typical wasp markings" they leave behind them (although they look more like giant termites than wasps and in distress sound more like elephants than insects) that cosmic rays have created and are now wreaking havoc with the usual stock footage of antelopes and giraffes.

At the time of his death in 1981 Jim Davis was a household name on TV as Jock Ewing in 'Dallas' and he is here supported by veterans Eduardo Ciannelli and Vladimir Sokoloff; the latter's daughter played by the soulful-eyed Barbara Turner (herself later the mother of Jennifer Jason Leigh).
