To light the fires in the episode, the crew made use of propane. Manners wanted the shots to be as close to the fire as possible, so they also used fireproof cameras. According to Manners, "They used a half a million dollar camera on a crane wrapped in asbestos" and ran it through the fire. For the scene in which the alien rebels incinerate people, the production crew used a "very dangerous" stunt known as a "full burn", in which a person is set on fire with the aid of a special suit. In total, the stuntman who performed in the scene was on fire for about 30 secondsquite a long time by filming standards. Special effects supervisor Tony Lindala supervised the creation of the faceless alien rebels, Dmitri's mutilation, and the incinerated victims of the rebels. Lindala also designed the rig used to infect Dmitri with the black oil.
