The title Massacre Collection was utilized in the marketing of the DVD releases of the films, and was not a part of their theatrical or initial home video releases. The films, the first six of which were each produced by Roger Corman, were marketed as an analogous series based on their related content as well as the inclusion of "massacre" in their respective titles. The Slumber Party Massacre trilogy has the distinction of being the first horror film series in history whose films were exclusively written and directed by women, in addition to the first spin-offfilm forming the Sorority House Massacre sub-series.
