In 2018, after decades of being thought lost, cult film label Severin Films discovered the original 35mm negative in Paris, France. This element contains the uncut version of the film.
As a promotional gimmick, packets of green "blood" were distributed to cinema patrons, who were instructed to drink it at a certain point in the film. Production consultant Sam Sherman came up with the idea of distributing the liquid gel-packs to the theatergoers, and said years later in an interview that he drank one of the packets, which contained an aqua-colored gel, and it made him sick to his stomach. Nevertheless, Beverly Miller (an associate producer of the film) said she actually witnessed dozens of teenagers drinking the stuff in the theaters that she managed in Kansas City.
