This film, like many Spanish films from the late 60s through the end of the Franco era, shot their racy scenes twice, once with the actors nude, and then again with clothes on. The covered versions mostly appeared in Spanish prints, but not always. The nude scenes would be included in the dubbed versions that were offered for sale to just about everywhere else in the world. This film has three scenes where the actresses are nude, and these appear an English dubbed print retitled Orgy of the Vampires. The Pagan UK releases on VHS and DVD are the covered version of the film, and this version now appears in the US on DVDs of questionable legitimacy from Alpha and Sinema Diable.
