When it comes to adaptations of "Carrie," the
Movie gore has come a long way since the first "Carrie." What
Fake movie blood — sometimes called "Kensington Gore," after the street of that name in London — began evolving long before 1976. For black-and-white films, when blood was permitted at all (the censorship guidelines of the Hays Code in Hollywood didn't much allow it), filmmakers used something quite simple: chocolate syrup. On black-and-white film, it made a starker contrast than red blood, and no one in the theater would ever know it was just Bosco or Hershey's.
At first, technical advances were modest. For "Psycho" (1960), employing state-of-the-art makeup design didn't mean using a new kind of blood, just a new method of delivery: the plastic squeeze bottle. It was brand new with Shasta chocolate syrup. As makeup supervisor Jack Barron explained it, "This was before the days of the 'plastic explosion,' so that was pretty revolutionary. Up to that time in films, we were using Hershey's, but [with the squeeze bottle] you could do a lot more."
