In 1943, Universal Pictures had the inspired idea to throw two of their monster characters into the same film, "Frankenstein Meets the Wolf Man," thus making it appear twice as alluring and scary as their prior entries. In the 1950s and '60s, a steady wave of repertory showings of the Universal Monster movies and other horror films were advertised with lurid names like "Horror Show," and were typically shown on double, triple, or marathon billings. In 1962, Bobby "Boris" Pickett released the song "Monster Mash," a novelty pop rock record whose lyrics told the story of a party attended by every famous movie monster to date, and the song became so popular that it's still a kitschy Halloween staple to this day.

As all of this proves, there is a long tradition of quantity-as-quality in horror cinema, a trope which leans into the more experiential and carnival aspects of the genre.
