Captain Jack house hunts

As I've mentioned before, I'm completely, utterly addicted to HGTV (and I don't care who knows it!) and I watch it endlessly. Lately they've run this ad for a show about what it's like to actually own a castle (Keys to the Castle). The guy who appears to be the host and who's walking around with the castle-owners looked like Captain Jack from Dr. Who/Torchwood (when oh when is that going to start???), but every time I paused or ran it again, I couldn't tell for certain. Well, wisteria_ confirms that it is indeed John Barrowman, so yay. I woulda watched it anyway, but now I will for cert. Info is here.
