Melissa Jaffer (Noranti) was to have had a larger part in the miniseries, but a bad reaction to the makeup forced her to drop out after only a few scenes. Most of her scenes were rewritten for other characters (most notably her officiating John and Aeryn's marriage went to Rygel) and later glimpses of Noranti are actually a look-alike.
Jim Henson's Creature Shop was responsible for most of the interesting aliens in the series. At one point, Crichton complains about being chased by the electric mayhem. The band on the The Muppet Show (1976) were known as Dr. Teeth and the Electric Mayhem and put out at least one album in the 1970s.
When Crichton is interrogated by the Eidolons and has to explain his predicament, he says he does it for the 89th time. This is a reference to Ben Browder's voice-over for the opening sequence of the 88 episodes of the Farscape (1999) series.
Virginia Hey is the only regular cast member from Farscape's original television run that is not in the miniseries (though she is visible for a moment in a flashback during Crichton's "recap flashback").
