Even though he’s not from this Earth (or any other Earths for that matter, “Mr. Johnson” is a creepy old man with dark glasses who needs constant blood transfusions. Kinda like looking into a mirror. If he doesn’t get said body beverage, his juice will turn into dust and he’ll become not unlike powered Kool-Aid™.
So what the flippin’ flap? Why can’t Mr. Johnson get his own dang blood from his own dang planet? For starters, his home world of Davanna (that sounds so made up) has been flash mobbed by nuclear war. Looks like Republicans exist on other worlds as well. Old Man Johnson is here to test our blood to see if it’ll help keep his fellow Johnsons from going double extinct.
Johnson uses telekinesis and eyeless eyeballs to command people to do his bidding, like his doctor, for instance. He even manages to talk Nadine, the doc’s sassy/hot nurse, into moving in to his multi-roomed house to give him nightly blood transfusions. He has a young male assistant/driver to round up park bums with the promise of alcohol for experimental purposes and different “phases” of his program. Free booze or not, you don’t want to be one of his experiments — they end up in the basement furnace. Party foul — that’s where recyclables go.
With human firewood missing all over town, the cops are closing in. Johnson unleashes a flying umbrella brain sucking creature that lands on your head and sucks out your brains. That’s kinda cool, but does it hold up in the rain?
Seconds before Johnson can remote-control Nadine into an experiment, the cops close in and turn on the sirens to make the car chase scene more official. Before they can shoot him in the umbrella, it’s the blaring alarm that causes Johnson to crash AND burn. (It was earlier revealed he’s highly sensitive to loud sounds. Guess that’s why aliens aren’t into metal. Pity.)
Final note: Not of This Earth (1957) is in black and white, so all those bottles of “blood” in Johnson’s fridge might very well be powdered Kool-Aid™.
