This episode was written by Dark Matter supervising producer (and former Stargate special features producer) Ivon Bartok. 'Ivon Bartok' would be, of course, an awesome character name on either Dark Matter or Stargate.
This episode was directed by longtime Stargate director Peter DeLuise. 'Peter DeLuise' wouldn't be quite as awesome a character name on either Dark Matter or Stargate as 'Ivon Bartok' (no offense, Peter!).
The lobby of Dwarf Star Technologies, with its unique rose pattern wall design, is actually Brampton City Hall in Ontario, Canada. The city loves Dark Matter!
The concept meeting for this episode was long and detailed. About an hour and a half into it, first assistant director Brandon Tataryn said, "This isn't going to be an easy smash and grab," echoing Three's bleak assessment early in the episode.
As a tribute to the Dark Matter Whiskey Club (an impromptu after-lunch whiskey-sipping gathering of cast and crew), one of the scientists was named Dalsker, a combination of two club favorites: Dalwhinnie and Talker. Cheers!
In an early version of the episode, Three informs the scientists, "We need your retinas." They react, horrified, until Two corrects him: "No, we need to scan your retinas." Three responds by shrugging, "Same thing." Ha, hardly!
In an early draft of the episode, Two shoots Alexander Rook dead in their final lab confrontation. Another version had Rook escaping to the space elevator and seemingly making good his escape, only to have Two drop a piece of heavy machinery down the shaft, crushing him in the lobby. Yet another version had Rook punished at episode's end with being implanted with one of the 'entities.' Ultimately, Alexander Rook is still at large!
Three's 'possessed response' was inspired by the 1978 version of Invasion of the Body Snatchers. You know it. Click here to watch.
