We love Coupling! I don't think we ever saw the final season, as we only caught it when it was on TV a few years back.

And Michael Sheen was awesome in the Underworld movies. Not sure if they'd be your thing, but I really liked them. And it made me giggle that they picked him to play a member of the Volturi after he'd been king werewolf in the Underworld series. I guess he's Switzerland.
