A wealthy business man discovers he has a brain tumor and seeks medical help. The business man finds a scientist experimenting with transplanting monkey heads on different monkey bodies. The business man decides to steal the head of Nostradamus from the prophet's crypt.
As preposterous sci-fi movies go, this one takes some beating. George Coulouris is the millionaire "Brussard" whose doctors tell him he has a tumour in his head and isn't long for the world. He refuses to admit defeat and concludes that some sort of transplant is probably his best plan. Allied with the inventive "Dr. Merritt" (Robert Hutton) who has been experimenting for ages on prolonging the life of a brain by sewing the head of one monkey onto the body of another, he procures that of Nostradamus (looks more like Rasputin to me, but anyway...) with a view to using his mathematical genius to capitalise on his already extensive fortune. Thing is, the headless body is a little narked at being decapitated and plumbed into some bubbling test tubes on a formica table, and so sets about wreaking a very static, but effective, revenge on his rapidly declining patron. What happens next? Well that doesn't really matter. By now the film has reached the depths of silly science backed up with some very dizzying visual effects and a few gadgets plundered from the school lab. The ending is fun, but in a ridi-colouloris sort of fashion. Not very good, sorry.
