The latter two editions topped the cast list (as given on the cover) with Lon Chaney, Jr., who did not appear in this film but did appear in Hewitt's Doctor Terror's Gallery of Horrors with Carradine, Gentry, and McGee. Also in the early 1980s, Regal Video Inc. released both of these films in identical packaging under the title Alien Massacre. Both films were retitled on-screen, which left Carradine's screen credit "John Carradine as" just before the title, incomplete.
