I captured this video from the movie Kingdom of Heaven. I really like the moment before Sybilla speaks, she's asking a question but, before she speaks she asks with her eyes and small head shake. I've noticed this happening lots, we tend to anticipate what we're going to say with our eyes before we actually say it. Anticipation isn't only for big movement and actions, anticipating before speaking, like in this video, can add a lot to an animation.
Surfing around on the net I found this cool blog with a pretty extensive archive or dvd screenshots. Great reference for emotions. Click the image to head there.
