Nicole Kidman took time out from promoting her new movie to speak at the United Nations headquarters today. The star of Australia was speaking out against violence against women and announcing that over five million people had signed the Internet-based petition in solidarity.

Melanie Reed of The Times Online describes her performance in Baz Luhrmann's epic as a "porcelain doll, looking frozen, brittle and vapid, staring at the camera with her oh-golly-look-how-I'm-looking-interesting blue eyes."

I would normally agree with Kidman's listless acting but I think it was all for a greater good. She was saving her entire repertoire of facial movements and range of emotional expression to convey the very important message of stopping violence against women.

Seriously, click through the pictures below. You haven't seen her face move this much since BMX Bandits.
