Catherine Zeta-Jones is very good-looking (especially in the late-90s) but I don't like the woman, and she's not that great an actress, she wouldn't be on the A-list if it wasn't for her relationship with Michael Douglas.
Even though I have to that she has very attractive appearance for some reason I cannot understand her celebrity status or say her acting abilities are other than average. Just a personal opinion, but I would normally avoid any movies with her in a starring role. I guess a pleasing appearance does not always translate to an attractive character.
I think she's a bit of a gold-digging phoney. She was gorgeous when I first saw her in Mask of Zorro, but now I don't fancy her at all. And isn't it funny how most of the characters she's played are bitches?
