The design for Paroos, the Priest, was based on "Father Jack" from the 1990's BBC America comedy series Father Ted.
The Creature Shop took the opportunity to develop a new flying rig to use for Paroos. It would have been adapted for use by Rygel for the fifth year.
If you look at Paroos's seat in detail, it is supposed to look like the "Grim Reaper" in profile. Paroos is using his arms to control his flight.
The location work was filmed in an area of the Australian bush that had been devastated by fires the previous summer, giving the episode a highly unusual look.
If the dome set here looks a bit familiar, it was previously used as the site of Grayza's seduction of Crichton in "What Was Lost," and D'Argo's room as "The Witch" in "John Quixote."
The song sung by the little boy next to Aeryn's Prowler was actually sung by composer Guy Gross himself, aided by a little digital trickery to make him sound younger.
Claudia Black had worked with director Geoff Bennett seven years earlier on the Australian series A Country Practice. Bennett had wanted to cast her in a feature film that was shooting while she was in Europe.
Among his many other credits, Bruce Spence, who plays Prefect Falaak, appeared alongside Claudia Black in Queen of the Damned, and also worked with Virginia Hey on Mad Max 2: The Road Warrior.
