A happy 52nd birthday to Callum Keith Rennie, who played Leoben the Cylon with a robo-hard-on for Starbuck in the Battlestar Galactica reboot. He's seemingly stayed very busy with TV work ever since, doing roles on everything from 24 to Californication to... there's a TV version of The Firm? Huh. Learn something new every day. We posted about him once before. And you can see several pics of Callum here, too.
