This opening episode is chock full of Stargate alum. Amanda Tapping, Ellie Harvie, Kavan Smith and Christopher Heyerdahl all worked on Stargate SG-1 and Stargate Atlantis. Director Martin Wood directed over 40 episodes of Stargate SG-1, as well as several others on Stargate Atlantis. Sanctuary's creator, Damian Kindler, was a writer on Stargate SG-1, writing over 20 episodes for the series. Finally, although David Hewlett was unable to reprise his role from the webisodes, Dan Shea (SG1's Sgt. Siler) has a non-speaking role as one of the police officers.
