One of the most frightening monsters in horror cinema. And there's Steve McQueen tossed in for good measure (he'd go on to do television's Wanted: Dead or Alive). The movie playing in the theater when the Blob spills out of the projector booth is Daughter of Horror (a re-cut of Dementia, 1955). If you haven't caught this movie, do so: it's held up and still delivers the goosebumps.
