Had The Blob director Irvin Yeaworth stayed faithful to his inspiration, the film would have been titled Star Jelly—meaning, Burt Bacharach's delightfully cheesy opening theme song would sound a lot different. Probably much cornier, too.

The film's inspiration came from a 1950 case in Philadelphia in which police officers found a mysterious "domed disk of quivering jelly." Before the cops could move the jelly, it dissolved right before their eyes. The sticky discovery was thought by those with powerful imaginations to be "star jelly," or the gooey remains found near fallen meteorites—space mold, if you will. Other, more rational folks pegged it as industrial waste, explained by the presence a nearby gas company facility.
