Holy blockbuster, Batman! "Catwoman" has its claws on some big-name stars.

With Halle Berry already signed on for the title role (see [article id="1475365"]"Halle Berry Eager To Dig Her Claws Into 'Catwoman' "[/article]), Benjamin Bratt is now in final negotiations with Warner Bros. to co-star.

In the film, which is based on D.C. Comics' antiheroine and feline seductress, the former "Law & Order" stud will play detective Tom Lone. Bratt's character also happens to be Catwoman's romantic interest in the story. And as if Berry isn't enough femme fatale for one movie, Sharon Stone will also appear in the flick as a villainous cosmetics magnate named Laurel.

One person you won't be seeing in this movie is Batman. "Catwoman" leaves the caped crusader and his boy wonder in the Bat Cave. Unlike Michelle Pfeiffer's version of the character in the 1992 film "Batman Returns," Berry's Catwoman is the movie's central protagonist.

The movie's screenwriter, Ed Solomon, also wrote "Men in Black" and co-wrote "Charlie's Angels" and "Bill and Ted's Excellent Adventure." The film begins shooting September 29 and is slated to hit theaters next summer.
