Her name is Oona Hart. She's been in a few TV ads before (most notably a Mitsubishi ad called "Art Girl"), and it took me forever to find out who she was. I agree; way, way hot.

But don't get your hopes up about seeing much of her in "Vanilla Sky". If I recall correctly, you see her for like 1.5 seconds in a party scene at the beginning. We need to see more of her!
