Development Silent Kill was written by Joe Weisberg and directed by
Fred Toye. Toye previously directed the fourth episode,
Grace. This is the first episode that Joe Weisberg wrote. He later writes the ninth episode,
Mutiny. The scene where Hal enters the hospital with Rick's harness was shot in an abandoned hospital in Toronto. During the scene where the actors had to react to the mech walking by, a crewmember walked through the space with a large pole with a light on it. This gave the actors the basic size and speed to track to. A scene was later shot without the crew member. Whenever the mech was meant to contact the shrubbery, the effects crew attached fishing lines to the bushes, which were shaken in sync with when the interaction was meant to happen. == Reception ==
