Re-released in the late 1970s under the new title "Grave Desires," on a double feature with Le grand amour du comte Dracula (1973), now re-titled "Cemetery Girls."
This was the first film in what became known as the "Blood Island" series.
Sam Sherman, independent producer and distributor of this and other drive-in films from the 60s to the 80s, came up with the marketing gimmick of offering female theatre patrons in the USA the opportunity to receive a free engagement ring set and become a Bride of Blood.
Riffed as "Danger on Tiki Island" by some original members of the MST3K crew, including Joel, Trace, Frank, Mary Jo and J. Elvis Weinstein under the Cinematic Titanic banner.
