Anne Hathaway who plays Catwoman in the upcoming 'Dark Knight Rises' has been speaking about the role with Empire magazine.

Here are the some blurbs from the article.
On Getting the role - It was in October 2010 and I had been hearing for a few months that there was going to be a new female character in the new instalment of the Batman franchise. Chris wanted to meet with me amongst, you know, scores of other girls - or women, however you wish to refer to us [laughs]. I was very nervous going into it, and there was some conversation about what the character was and everyone, literally everyone, I talked to said, "Well they're not confirming anything but I personally think it's Catwoman."
I just thought, "No, no, Chris isn't going to go for Catwoman! [laughs]". Because I'm the all-seeing oracle, apparently. I went in with one character in mind and after about an hour of talking he says, "Okay, so the part is Catwoman," and I had to try to, all of a sudden, completely switch from the one character that I was subtly trying to subconsciously make him think of to Selina. Who, thank goodness I'm a huge fan of. Chris and I talked for about another hour and then about three-and-a-half months later we did another screen test and the week after that I found out I had the part.
On The Suit - It's not, you know, something I would choose to stay at home and watch a baseball game in, however... But it certainly got the job done and that's all that matters. I got chills when I saw that (Goggles). I was so happy they had such a clever solution to a really iconic but sometimes unnecessary part of the costume.
On Following Michelle Pfeiffer - How do I say this without sounding like a know-it-all? I think that Catwoman depends on the Gotham City she lives in. The characterisation of her is informed by the world around her. So what I sought to do with my Selina was make her part of Christopher Nolan's Gotham, just as I thought Michelle Pfeiffer's was very brilliantly a part of Tim Burton's.
