The advertising for the double feature of "Horror of Party Beach" and "Living Corpse" capitalized on a gimmick first utilized by director William Castle, in which newspaper advertisements included a call-out that stated: "For your protection! We will not permit you to see these shockers unless you agree to release the theater of all responsibility for death by fright!" Theaters were encouraged by the distributor to have patrons sign a "Fright Release" before they took their seats. The trailer for the double feature also included this claim. Although billed in its promotional material as "The First Horror Monster Musical," all the songs heard in the film were presented as either soundtrack music or source music, as opposed to the style of a traditional musical with songs sung by central characters of the story. Ray Dennis Steckler's "The Incredibly Strange Creatures Who Stopped Living and Became Mixed-Up Zombies" also made the same claim a few months earlier. As a tie-in, a monographic fumetti comic book by Wally Wood and Russ Jones detailing the film's story was released by the Warren Publishing Company under its Famous Films masthead. It has a 35-cent cover price.
