Actress Rosario Dawson has confirmed reports Angelina Jolie will be signing on for the sequel to Sin City and production on the film is on hold while the star is pregnant. Jolie is currently expecting a baby with Brad Pitt, but is eager to co-star with Dawson, who will reprise her part as rogue hooker Gail in the movie. The Mr. And Mrs. Smith star is rumored to be playing the role of "A Dame To Kill For" in the next installment of the film. Dawson says, "The film's kind of been postponed because Robert (Rodriguez, the director) has been interested in Angelina Jolie for the lead. But she's very pregnant right now. So that's putting an understandable hold on the film." The second film will be based on Frank Miller's graphic novel stories "A Dame to Kill For" and "Lost, Lonely and Lethal," according to website, moviehole.net.
