How many of y'all knew already that Kristanna Loken played the female killer cyborg in Terminator 3? There was one very creepy scene in a fight sequence with Arnold (the original Terminator) where he grabbed her from behind, then she reversed her hips and wrapped her legs around him, reversed her arms and grabbed her, then rotated her head 180 degrees and ended up facing him. She never changed expression, either.
Her frown was intense enough to break glass. And the only time she smiled was when she tasted someone's blood to see if her victim was on her target list. She nailed that part. A very good actress who hasn't had the opportunities I think she should have had, although her website lists more acting gigs than I knew of.
