1997
Julie Christie - Afterglow
Judi Dench - Mrs. Brown
* Jodie Foster - Contact *
Pam Grier - Jackie Brown

I'm the biggest Kate Winslet fangirl ever, but anyone that says she was robbed this year is pretty insane.
1998
Cate Blanchett - Elizabeth
Samantha Morton - Under the Skin
Gwyneth Paltrow - Shakespeare in Love
* Christina Ricci - Buffalo '66 *
Emily Watson - Hilary and Jackie
If TV movies count, boot Blanchett and the win goes to Angelina Jolie, amazing in Gia.
1999
Julianne Moore - The End of the Affair
Cecilia Roth - All About My Mother
* Hilary Swank - Boys Don't Cry *
Kate Winslet - Holy Smoke!
Reese Witherspoon - Election

2001
Maggie Cheung - In the Mood for Love
Nicole Kidman - Moulin Rouge! (and The Others)
Charlotte Rampling - Under the Sand

If TV nominees are allowed, I'd boot Cheung and Rampling for Emma Thompson in Wit and Judy Davis in Life with Judy Garland: Me and My Shadows.
2002
Maggie Gyllenhaal - Secretary
Isabelle Huppert - The Piano Teacher
Diane Lane - Unfaithful
Julianne Moore - Far from Heaven
* Samantha Morton - Morvern Callar *
If TV movies were allowed, I'd boot Huppert for Uma Thurman in Hysterical Blindness. Or maybe not. But she'd be a close sixth, since the year falls off fast after those six.
2003
Zooey Deschanel - All the Real Girls
* Scarlett Johansson - Lost in Translation *
Charlize Theron - Monster
Uma Thurman - Kill Bill, Vol. 1
Evan Rachel Wood - thirteen

Pardon me, I am in post-Oscar-but-pre-good-movie-hype mode. I tend to post a lot of things like this then look back in like two years and say "WHAT WAS I THINKING???!!!"
