In 1958, the world was introduced to an intergalactic horror movie about an alien gelatinous goo that consumes everything in its wake: The Blob. The '50s B-movie has gone down in history as a classic monster flick, that would later even spawn a gory remake in 1988. But, this terrifying UFO film isn't entirely fiction, and you may want to keep an eye on the sky after hearing the shocking true story that inspired The Blob.
