On 29th October 2022, BBC Three announced that they have commissioned Euston Films to produce a 6-episode second series of the comedy horror. Series two will be filmed and broadcast in 2023.
Lead character Jamie Walsh was named after actress Jamie Lee Curtis and Mark Patton's character Jesse Walsh from Nightmare on Elm Street 2: Freddie's Revenge.
Karen's line on the promenade during her tour "one stop shopping and eating, everything you need at your fingertips" is a direct quote from Dawn of the Dead (1978).
None of the series was filmed on an actual cruise ship, however some exterior shots were captured on Belfast's SS Nomadic at the historic Hamilton Dock.
The ship theatre is "The Romero Theatre" after the iconic horror director George A. Romero.
