Sure. These are the Hathaway movies I've seen:
Havoc
Rachel Getting Married
Devil Wears Prada
Ella Enchanted
Get Smart
Love & Other Drugs
Brokeback Mountain
She's a good actress with a strong suit in sitcom-y, snappy dialogue. She can play "bad girl" but in a very high school, young-adult kind of way. She lacks the innate sultry, sexy, slinky aura of Selina Kyle. She's not as dangerous, womanly, sophisticated or mysterious, as Catwoman needs to be.
I have a strong suspicion that Nolan had Marion Cottilard cast, and she had to back out due to her pregnancy.
I also don't think Anne's "off-beat" casting is comparable to Heath's casting. It's evident from Monster and Brokeback that he had a lot of buried, intense crazy energy in him. And I was excited to see him as the Joker from the beginning. But Anne doesn't have that devil-may-care yet vulnerable oxymoronic quality about her. Unless she completely changes her voice, her style of "reacting" (eye blink, pursed lips) that she's used in other movies, and just full-on morphs into a new human being, I'm not going to be looking forward to her in the Dark Knight rises.
I will, however, be looking forward to the possibility of Darren Aronofsky directing The Dark Knight (3) in 2017. Or later. I'll wait.
