Monica Bellucci, yes.
Britain's Saffron Burrows, though EON might think she's too 'old' for the part.
Which actually raises the question, how old is too old? After this recent run of 20something Bond girls it might be interesting to see Bond with someone closer to his own age, or even older. There are plenty of women over forty who are still incredibly hot. Monica Bellucci has already come up here, and have you seen Famke Janssen these days (not suggesting bringing her back, just making a point)?
I'd certainly like to see a Bond girl who has the same veteran edge Bond has.
I like this line of thinking. I would really want a more mature actress if the character is in some sort of role that would require a signifigant amount of experience. We don't want another 20 something nuclear physicist, do we?
While I certainly wouldn't mind seeing an actress that's right around Craig's age, I don't necessarily think that we need to have someone around his age. If the types of Bond girls that we've had in the past two films had been like their counterparts in the four films prior to CR, then I would agree, but the 20-something Bond girls we've had in CR and QoS have been the best of the best (with Eva Green being absolutely head and shoulders above every other Bond girls, at least in my opinion). There's plenty of other 20-something actresses who could come in and hold their own with Craig in future films, and if the scripts call for them, then great. I certainly would love to see actresses like Olivia Wilde (who was reportedly the runner up for the role of Vesper), Yvonne Strahovski, Rose Byrne, and many others in a Bond film in the very near future.
Now, there is a great number of 30-something actresses that would be fantastic in future films as well. If we're going for actresses closer to Craig's age, then I'd be all in favor of actresses like Diane Kruger, Selma Blair, Rachel Weisz, Kate Winslet, Paz Vega, or many other actresses that have been mentioned on these boards.
