Though many of the show's scenes set on the interior of the ship were filmed on sets in a Canadian studio, a few were shot on an actual Art Deco ocean liner from the 1930s, the RMS Queen Mary, that is permanently moored in the port of Long Beach, California. Often used as a filming location for movies and shows set on luxury ships, the Queen Mary also contains a hotel, restaurants and bars, and event spaces. At the time when this series filmed its scenes on the vessel (autumn 2021), much of the ship was closed for renovation.
Originally title called "Career Opportunities in Murder & Mayhem".
Jane Atkinson and Mandy Patinkin costarred in multiple seasons of Criminal Minds together prior to this show.
