Berry was on the cusp of being an A list star.
Prior to Die Another day there was "Swordfish" then X-men 1 and 2.
I'd say people knew by then.
X2 came out after DAD.
Again, I'm not saying people didn't know her. I am saying that she was on-par with the other Bond girls of the era in being known, but not being house hold names quite yet. During the production of DAD, she became that household name (which, I'm sure the producers loved, considering they probably got her into a "pre-A-list" contract, but were also then able to market the hell out of her since the movie came out "post-A-list"). I would argue that Hatcher and Yeoh were on the cusp of being A-Listers as well. However, it didn't quite work out for them.
