This story formed the basis for the 1966 Batman TV episodes "Zelda the Great" and "A Death Worse Than Fate", switching the character of Carnado the magician/escape artist to Zelda the Great, played by Anne Baxter. The character of "Eivol Ekdal" the death-trap inventor, played on TV by actor Jack Kruschen, remains unchanged from comic to teleplay.
