Actor Christopher Heyerdahl, who portrayed a Wraith in multiple episodes of Stargate Atlantis, has been cast as an ancient vampire for the upcoming season of True Blood on HBO, according to a report by Deadline. The move from siphoning the life force of humans in space to draining their blood in Louisiana should be an easy transition for the actor, who has also played a vampire in the Twilight saga. While Heyerdahl has moved to a more earthly pursuit, fans of Stargate Atlantis can find a number of screen-used props and wardrobe items from the series – including a Bolakai throwing disk to a pair of Atlantis hard hats and much more – at the VIP Fan Auction’s Stargate page.
