I hear that Sanctuary is going to do a musical episode in the upcoming season. What can you tell us about it?

The first thing to know is it is not going to be like Glee. According to Amanda Tapping, 46, who plays Dr. Helen Magnus in the sci-fi fantasy TV series, “It’s more like The Exorcist: The Musical.”
The episode will be written and directed by the show’s creator, Damian Kindler, so it will stay true to form for the Syfy series, with a little added panache. “It was one of those things where we were, ‘How are we going to do this?’ It was outside of our comfort zone,” says Robin Dunne, 34, who plays Dr. Will Zimmerman. “Amanda and I were in the studio recording. It was like being a rock star for the week.”
