I used to have a special place for Kirsten Dunst. That quickly turned into a certain disgust with her. I guess she's become too arrogant.
I wouldn't use the word crush either these days (and age), but there are some actreses that I like seeing in movies:
Julia Stiles
Scarlett Johansson
Not so much though, now that she's gained a lot of popularity.
And of course Norwegian singer Marit Larsen.
