Trivia: In 2014, a Details Magazine interviewer asked Wentworth Miller about his experience playing a "fish monster" in this episode, his first onscreen acting job. Miller responded: "Honestly, I was completely out of my depth and doing whatever I could to keep up. They glued this prosthetic piece covered with scales to my chest. Then there was a piece over it that looked like human skin. I had to peel through the top layer to reveal the beast within. Deep into the third hour of this, the makeup artist says to me, 'We only have one of these pieces to tear through, so you need to get this right.' Hollywood can be a deeply strange place."
