Just saw the one with Sophie Marceau in it a few days ago, and I had to look up who she was right away as she really got me going with her look in that movie. Didn't have a clue who she was before that. So she rates very high for me. She's got a really sensual and catty look.
Ursula Andress does have a special place in my heart for me though. I'm not even that old but when I think of hot babes from the 60s in any kind of film I think of her and get all warm and fuzzy. She's got that greek godess kind of hot look to me. No comparison with Halle Barry, who I don't think is particularly attractive at all (her breasts aren't even that nice if you have seen them in Swordfish).
As I have yellow fever I might think I would like the asian bond girl but I don't find her particularly attractive - perhaps more just her acting is not sensual, she was more of a pure ass kicker.
