There are a number of simularaties between this episode and the Sandra Bullock film 'The Net'. Both characters set fun fair as a meeting point only to be outsmarted by the killer before escaping with the benefit of the carousel.
The original title of the episode was "Thrill Rides".
Many of the scenes were filmed at Santa Monica Pier under strict Covid-19 restrictions. For the close-ups set on the Ferris wheel, a replica was built in the studio using parts found at an amusement park graveyard.
This is the shortest episode of the show, running to only 37 minutes.
