Magda Szubanski first appeared as Furlow in Season 1's "Till the Blood Runs Clear." She is best known for her work on the talking animal movie Babe (whose creatures were puppeteered by many of the Farscape puppetry team).
Kent McCord returns as the Ancient, first encountered in Season 1's "A Human Reaction." McCord has a long career in American TV, including starring roles in cop series Adam-12, and Galactica 1980, and is Treasurer of the American Screen Actors Guild.
Ben Browder and Wayne Pygram were amongst the last people ever to ride the rollercoaster at Luna Park for the sequence where Crichton tries to kill Harvey. The rollercoaster was dismantled shortly after filming was completed and transported to Queensland.
The Luna Park sequences were originally scripted to be shot on the river beside Farscape's studios at Homebush Bay, but director Peter Andrikidis thought that the funfair would be more spectacular.
When Crichton and Scorpius are riding the rollercoaster, Sydney Harbour Bridge can be seen in the background.
Writer Carleton Eastlake worked with David Kemper on The Outer Limits, The Equalizer, and seaQuest DSV, and traveled to Australia as Executive Consultant on the latter part of the third season.
Dam-Ba-Da village had to be recreated on location, as the original sets used for "Till the Blood Runs Clear" no longer existed. The crew traveled to the sand dunes at Kurnell, south of Sydney, on the flight path into the airport.
Filming Dam-Ba-Da seems to bring adverse weather conditions: hailstones hit the set during "Till the Blood Runs Clear's" filming in Season 1, and floods affected shooting of "Infinite Possibilities," although luckily the waters receded in time.
The Kurnell area was also used for the location shooting of Aeryn and Dregon's walk through the desert in Season 2's "Look at the Princess" trilogy. At one time, it was a notorious dumping ground for dead bodies by Sydney's criminal fraternity.
Ben Browder pulled his harmstring while running across the dunes during the filming of this episode, although he kept going until the director called "cut."
Carleton Eastlake suggested that Rygel's wound should be in the same place that Xhalax gutted him and Stark sewed him up four episodes earlier in "Relativity."
