Summer Glau has played two iconic characters in recent sci-fi history, aka River Tam in Firefly/Serenity and Cameron Phillips in Terminator : The Sarah Connor Chronicles, she deserves to be on top of the list.


I've never seen anyone that pretty, beautiful, attractive and with all that, look so innocent, then turn around and pull off playing a character that's tough as nails. What more could you want? Well, more of her on the big screen. Whew...makes your blood boil. She could be what Sigourney Weaver was in the 80's. Hope she makes it to the top.
