It’s very possible! Both she and director Christopher Nolan are interested!
“If Nolan’s interested, I’m very interested,” Hathaway, who plays Selina Kyle (Catwoman), told a media tabloid. “I think it would be lovely to see more of her, but only if it’s with the right people. She lives in this Gotham City, and so it would have to be established by the people who have made this Gotham City. For me, at least.”
Nolan himself even thinks the Actress deserves her own film saying, “Anne is incredibly precise and articulate about the psychology of the character. She’s really built it from the ground up, it’s a delight to watch her perform, the things she does in those heels is not to be taken lightly… I certainly think she deserves her own solo movie, she’s incredible.”
Please, please, please let this happen!! OMG!!
I JUST CAN’T WAIT!!!!!
“I loved Catwoman’s sense of humor. I love how sly she is. I love how she, to use a cat metaphor, walks the fence and you don’t know which side she’s going to come down on. She’s totally independent. And let’s face it, she’s badass.” - Anne Hathaway
“What’s come before doesn’t limit or even affect this new version. It doesn’t affect me because each Catwoman – and this is true in the comics as well – she is defined by the context of the Gotham City created around her. Michelle Pfeiffer’s Catwoman was informed by Tim Burton’s Gotham and Eartha Kitt was informed by Adam West’s Gotham. You have to live in whatever the reality of the world is and whatever Gotham is.”
