What's her name??

Can someone tell me the name of this actress? It showed up on my horoscope recently and I know her name and the movie, but for some reason, I can't remember either.
It's driving me crazy that I can't remember her name and my obsessive personality needs to know it or else I'll go insane.
If you know what this actress' name is, or the name of what movie this image is from, please let me know.
