I know people are doubting her, but doesn't that always happen at first? Look at the response Andrew Garfield got when he was first announced as Spiderman (mainly from losers who had never seen him in anything) and the of course, the most obvious example, Heath Ledger. I can see her pulling off the shy Selina and sexy Catwoman. She has it in her. Personally, I kind of wanted Maggie Gyllenhaal to 'come back' as Catwoman. Sounds stupid, but it would've been cool.
