Magda Szubanski makes her first appearance as Furlow, who would play a critical role in in Season 3's "Infinite Possibilities". She is best known for her part as the farmer's wife in the Babe films.
Jeremy Sims who play Rorf would return in the "Liars, Guns, and Money" trilogy. A highly regarded actor in Australia, he has been nominated for numerous awards.
Jo Kerrigan also returns in "Liars, Guns, and Money" and would then play the treacherous scientist Linfer in the third season's "Losing Time".
Chrichton is in full pop culture mode in this episode, referring to Butch Cassidy and the Sundance Kid, Jesse James' The Hole in the Wall Gang, and Star Trek: The Next Generation's Klingon security chief Worf in the space of twenty seconds.
Furlow's reference to the "kindness of strangers" comes from the Tennessee Williams play A Streetcar Named Desire. Obviously its fame has spread to the Uncharted Territories.
At first, Virginia Hey was not happy about the idea of the photogasms, but realized that they added an important aspect to showing that Zhaan was a plant.
Of the numerous aliens in the background in this episode, Dave Elsey always hoped that the Fish Girl would get a story written around her, as the Sheyang had after the pilot. As of this writing, it hasn't happened.
"Till the Blood Runs Clear" was filmed at Stockton Sands, north of Sydney, which had the necessary desert feel, without having to take the production unit too far from their home base at Fox Studios.
In one of the outtakes, Crichton and D'Argo go into an embrace and give each other a big fake kiss at the end of their bonding session.
This episode was shot at Stockton Sands in Newcastle (near Sydney).
D'Argo: What is a pain in the ass?
Zhaan: Human speak, I believe, for someone irritating, stubborn, obnoxious.
Rygel: A simpleton, a dolt, idiot...
D'Argo: I get the idea.
Rygel: Zhaan, are you fully clothed?
Zhaan: I'm not wearing a scrap. I'm as nude as a new-born baby.
Rygel: Then go away, and don't insult my eyes with your naked blue extremities.
Zhaan: Which ones in particular don't you like? Show them to me.
Rygel: No thank you. Help, help! A mad Delvian exhibitionist is forcing herself on me… visually!
Zhaan: It's called a photogasm.
Rygel: I'll get a mop and bucket.
John: I just wanted to go home!
D'Argo: Well, no matter the cost to the rest of us.
John: What? Oh, right, remind me, who was it that chopped off Pilot's arm for a return ticket? No, wasn't me. I was too busy saving your ass. Too busy keeping your deepest family secrets.
D'Argo: Shall I chronicle the rest of that relationship?
John: Relationship? Oh, we have a relationship. No wonder you want to kill me.
D'Argo: I once thought-
John: Thought what? No no, no, no. Thank me tomorrow. I saved your ass today.
D'Argo: You tortured me.
John: I saved you! You know what? I have no idea what goes on in that tiny brain of yours, D'Argo.
D'Argo: And I have no idea why you do anything that you do.
John: Catch a clue, pal, because I am tired of sticking my hand out only to have you snap at it.
D'Argo: Every time I let down my guard, you disappoint me.
John: Sorry. I'm only human.
D'Argo: You look so much like a Peacekeeper, I often forget.
John: Listen, Aeryn... Crais' offer of amnesty... You're not seriously considering it, are you? You don't think he'd keep his word, do you?
Aeryn: I believe he would restore my commission and give me honorable retirement. But what he means be honorable retirement is radiation-induced brain fever to bring on the living death.
John: Well, if you knew the offer was bogus, then why did you listen to it?
Aeryn: Because it was nice, just for a moment, to believe that it was genuine. That I could go back.
