Scariest Woman in Hollywood

This is the scariest woman in Hollywood. I present Ms. Tilda Swinton. No, not because of the White Witch thing, but rather because how her on screen image is so delicate and demure, but off-screen.... je ne sais quoi.

She won an Oscar for her work in Michael Clayton. Channeling Jody Foster much?

Stole the show in Constantine, IMHO, as the archangel Gabriel.

Or is she channeling Charlize Theron from Monster?

I don't know... someting scary about chameleons. :)
