Syfy has officially announced that they’ll be renewing the TV series Sanctuary for a fourth season. The show has consistently averaged 1.5-2 million viewers per episode according to various ratings sites and with the smaller budget compared to some larger shows that have had similar ratings numbers recently that were given the axe, it’s an easy pick-up for the channel. Additionally, it helps that the show has a relatively short season to it as well. Production for the 13-episode season will begin production this spring with a possible fall premiere. Sanctuary stars Amanda Tapping, Robin Dunne, Agam Darshi, Ryan Robbins and Christopher Heyerdahl. The series, shot mostly on green screen, is the first North American show to exclusively film with the RED camera. Plot Summary: Sanctuary blazes a trail across the TV landscape with never-before-seen production technology. Starring Amanda Tapping, best known to fans as the brilliant Col. Samantha Carter on Stargate SG-1, Sanctuary is the first series to shoot extensively on green screen, using virtual sets and extraordinary visual effects. Sanctuary follows the adventures of the beautiful, enigmatic and always surprising Dr. Helen Magnus (Tapping), a brilliant scientist who holds the secrets of a clandestine population – a group of strange and sometimes terrifying beings that hide among humans.
