James Marsters. Yes, that's right, Spike from the amazing Buffy the Vampire Slayer.
Sources have confirmed to Entertainment Weekly that James has been confirmed for the Battlestar Galactica prequel Caprica for quite a sizable arc.
...Hear that sound? That's the sound of my sister's squeal all the way from Connecticut. She raised me on Buffy. It's the premise for our relationship as sisters. It's our own personal '6 Degrees of Separation from Kevin Bacon'. For us, everything relates back to Buffy. She also happens to be a huge Battlestar Galactica fan. So it's a win-win for her.
Marsters will play a terrorist by the name of Barnabas Greeley in a minimum of three episodes (squee!). "Driven by desires both moralistic and carnal, Barnabus is as lethal as he is unpredictable."
SO excited. So excited I will probably actually watch SyFy to catch him on this. January 22nd is the debut.
