I was too indecisive to vote in these, but I'll comment. Hard to argue with the top of the list, although I would've had both Blanchett and Ullmann top five. Kidman in the top ten is a bit generous, IMO.
Also glad to see Audrey Hepburn and the new love of my life Deborah Kerr in the top 20, I wouldn't have expected that. I'd put them both ahead of Liz Taylor, though.
