Samantha Tapping (”Stargate SG-1″) has a new gig on “Sanctuary”, a sci-fi web series that SciFi Channel has picked up for this fall tv season.

The show is about Dr. Helen Magnus (Samantha Tapping), a brilliant scientist who discovers a group of unusual beings have been living among humans for ages. Thus, she tries to track them down with her team and offer them sanctuary. Get it? Oh, and by some miracle of science she’s 157 years old!

Her daughter, Ashley (Emilie Ullerup), is also part of the team. She’s in it for the action of the chase. In the pilot episode, they recruit a forensic psychiatrist named Dr. Will Zimmerman (Robin Dunne) who isn’t as good as Ashley in the field. He seems to have a few problems adjusting to the idea of a world where monsters and supernatural beings exist. Ryan Robbins plays the requisite tech guy, Henry, and Christopher Heyerdahl plays Helen’s arch enemy, John Druitt.

“Sanctuary” was created by Damian Kindler and is produced by Tapping herself (along with a few of the “Stargate” producers like Martin Wood and N. John Smith). The show depends almost exclusively on green screen technology, which I feel can be great for science fiction, but I’m not sure if every building needs to be a cgi creation. I’ll guess I’ll just have to wait for the October 3rd (9/8c) premiere before making up my mind.
