13 Ghosts is a 1960 American horror film written by Robb White and directed by William Castle. The film stars 11-year-old child actor Charles Herbert, Jo Morrow, Rosemary DeCamp, Martin Milner, Donald Woods, and co-features experienced character actress Margaret Hamilton. Throughout the film, Buck (Herbert) refers to Elaine (Hamilton) as a witch. Though this is never confirmed, the film hints at the possibility. These inside references were an acknowledgement of Hamilton's best known role as the Wicked Witch of the West in The Wizard of Oz (1939).
