About Me
IMDB Listing for Cash Flagg, Jr.
"He was once a scientist who specialised in human evolution and had worked hard on it for many years. At some stage during his research he discovered he was able to access mankind's atavistic tendencies, and harness them for his own malevolent schemes. He created a serum extracted from the gonads of gibbons which, when passed through the balls of chimps at light speed in a special atomic container, could turn men into monkeys. He then set out contaminating our very own water supply, so I've had to develop an antidote. Which is why everybody is back to normal."
