He's the oldest, most dangerous vampire on the planet. And now he has a face.

Following weeks of hype and speculation, The Vampire Diaries has cast a relative unknown actor in the role of Klaus, the Original blood sucker set on sacrificing Elena and breaking the curse of the moonstone.

Say hello to Joseph Morgan.

We know what you're thinking: Who?!?

The 30-year old Brit has a thin resume in the States, but producer Julie Plec told Entertainment Weekly last month the show likely preferred an actor "that no one’s really familiar with," so he can be exploited, "in all the good ways," of course.

The Vampire Diaries has succeeded on that front: this role will mark Morgan's first network TV appearance. He has enjoyed parts on the big screen in Alexander and Master and Commander.

With just hours to go until tonight's 2011 premiere, sound off now: Good choice?
