As comic-book fans know, the Selina Kyle character is the secret identity of Batman’s sometime paramour (and sometime foe) Catwoman, and Bane is a muscular bad guy powered by an addictive drug called Venom. But a news release from Warner Brothers gave no descriptions of how these characters would be utilized in Mr. Nolan’s film; Mr. Nolan said in a statement only that Ms. Hathaway was “a fantastic addition to our ensemble as we complete our story” and that he was “delighted to be working with Tom again and excited to watch him bring to life our new interpretation of one of Batman’s most formidable enemies.”
“The Dark Knight Rises” is planned to be released on July 20, 2012, with a screenplay by Mr. Nolan and his brother, Jonathan Nolan, from a story by Christopher Nolan and David S. Goyer."
The same reported on Deadline.
