Unknown to himself or the producers, lead actor Richard Hatch was suffering from stage 4 pancreatic cancer during principal photography. Hatch notified director Adrian Stewart of his illness early in 2017. Three days of scheduled re-shoots were canceled as Stewart and the producers quickly assembled a rough cut of the film, which Hatch was able to view before his passing on February 7, 2017. The film is dedicated to Hatch, with the card "In Loving Memory of Our Good Friend Richard Hatch" opening the end credits.
On the wall is a print of Maxfield Parrish's 'Young King of the Black Isles'. Originally painted as a frontispiece for Collier's Arabian Nights VIII from 18 May 1907. It depicts a sultan brought to tears after hearing the sad story of a young king.
