Amazing But True
Believe it or not, the 1950’s classic horror movie The Blob is based on an incident that happened in the ‘50s when Philadelphia policemen stumbled upon a quivering purple lump that had crash landed in a nearby field, as if Grimace had suddenly been stricken with bubble-gut in the middle of a hang gliding trip. According to the responding officers, the mass was like a giant glowing jelly ball, and it left a sticky residue when touched, because of course the first thing you would do when encountering a mysterious Plutonian blob is shove your hands into it.
The two cops wanted witnesses to corroborate what they were seeing, so they radioed for two fellow officers to come take a look at it, if for no other reason than to prove they hadn't just been pranked by a couple of hopheads and alkies with fifty jars of jelly and absolutely nothing better to do.
The blob quickly began to fall apart, and within half an hour had completely dissolved, leaving behind no trace that it had ever existed.
Regardless of how ridicu- lous the story may seem, an official government report was made of the incident, although that likely had more to do with the Cold War than a fear of extraterrestrial preserves.
"Space jelly, eh? Those crafty Russkies." Who knows what it actually was—maybe some passing pedestrian dropped a Jell-O mold and, before the officers could come back to the scene, some passing animal came and ate it. Or maybe the guy just made the whole thing up.
Years later a man named Irvine H. Millgate (who at one point in his life had the very unique job title of "Head of Visual Aids for the Boy Scouts of America") needed to come up with a premise for a low-budget monster movie. Instead of pulling something completely out of thin air, he remembered the Philadelphia incident and used it as inspiration to assist him in pulling off something completely unlikely. The Blob became an unlikely hit, so if that purple blob creature actually returns to Earth someday, we assume the first thing it's going to do is sue for unpaid royalties (and then get shot by Tom Cruise in the remake).
