The film's working titles were Thirteen and Ghost Train. Although onscreen credits note "color scenes by Path," the viewed print was in black and white. The New York Times review erroneously lists the film's running time as 128 minutes. The Filmfacts review mentioned the Illusion-O "gimmick," which was the studio's name for the effects created by a pair of special glasses, called a "ghost viewer," that the audience would wear. One window of the glasses was tinted blue and one red; when the viewer looked through the red one, ghosts would appear on the screen, but when the viewer looked through the blue, the ghost could not be seen. The review added that producer William Castle appeared in a prologue to the film to explain the process, but Castle was not in the print viewed. In 2001, Warner Bros. released a remake of 13 Ghosts, titled Thir13en Ghosts, directed by Steve Beck and starring Tony Shaloub and Embeth Davidtz.
