Curtis,
i always found Penelope Cruz was a real Jeckyl & Hyde type of a woman - sometimes she really does it for me, and other times she just has hairy armpits. Scary.

My picks would have to be Julia Roberts in Pretty Woman, Marina Sirtis in ST:TNG, Katie Holmes in Dawson's Creek, Mena Suvari in American Beauty and Kate Hudson in Almost Famous. Also props to Angelina Jolie in pretty much everything she's been in!
