As my Facebook followers know, I'm obsessed with British actor Rufus Sewell and feel he embodies something of the "Casanova": handsome, intelligent, makes love to a woman with his eyes. Here he is in "Zen," a BBC mystery series based on the books by Michael Dibkin. Rufus often plays historical characters, but here he we get to enjoy him in an Armani suit strutting through the streets of Rome, sigh.
