The Oscar-winner will join a cast that includes Johnny Depp as The Riddler as she plays the whip-carrying burglar. The character has also been played by Michelle Pfeiffer and Halle Berry.
A studio executive said: "Cher is Nolan's first choice to play Catwoman. He wants to her to portray her like a vamp in her twilight years.
"The new Catwoman will be the absolute opposite of Michelle Pfeiffer and Halle Berry's purring creations."
