Claudia Black is an Australian actress, surprisingly, who is both hilarious and sexy and without whom the last few seasons of SG-1 would have been doomed to boredom and failed miserably. I first came across her in Farscape and Beastmaster (is my sci-fi nerdom showing?) and fell in love with her on Stargate where she plays Vala Mal Doran, a partially reformed thief/con-artiste who comes onto everyone, lies constantly and bounces around like she's enjoying herself all of the time. Somehow she manages to be lovable, sincere and form meaningful relationships with her new friends.
But whatever, she has her own action figure.... isn't that awesome?
