There are no insects naturally occurring on this planet. This seems very unusual, since insects are important in the life cycle of Earth, including pollination of plants.
Crichton: Man, you should have met her mother.
This Crichton never actually met Aeryn's Mother. It was the Crichton who died in "Icarus Abides". However, he did see a video image of her, and no doubt heard stories about her ruthlessness.
Chiana: Seriously - that's the longest this blindness has ever lasted.
Paroos: Then stop using the vision, twizzet.
Chiana: I'm sure you'll be the first to miss me, next palace coup.
Paroos: Should've let the bugs eat your hide.
D'Argo: (to Crichton and Aeryn) You can fight against it.
Crichton: D'Argo, just hit me! Knock me out!
(D'Argo hits him, to little effect)Crichton: Hit me harder you big sissy!
Title:
The episode's title, "A Prefect Murder", is a nod to the 1998 movie A Perfect Murder which starred Michael Douglas, Gwyneth Paltrow and Viggo Mortensen. This was itself a remake of the Alfred Hitchcock film Dial M For Murder, which was made in 1954.
Father Ted:
The look and design of Paroos the Priest was deliberately based on Father Jack from the 1990s comedy series Father Ted, which was about a group of Irish Priests.
