Best actress of the current crop?
Maybe so, in my opinion.
There are a lot of great ones out there right now, but Natalie Dormer (who I first noticed as Anne Boleyn in the Tudors) has shown great range, with deeply compelling portrayals. It doesn't hurt that she's fun to look at as well. Her facial expressions are so expressive, I bet she could do a great performance just miming alone.
Anyone else vote for her, or who would you put up to compete with her?
