The Black Dahlia is the one I'm most looking forward to. It is about an unsolved L.A. murder case from the 40's. Another interesting one is
The Other Boleyn Girl. Natalie Portman plays Anne Boleyn while Scarlett plays her sister Mary. Both vie for the affections of King Henry VIII of England (portrayed by Eric Bana). If you recall your English history, Anne looses her head over Henry, so to speak. Scarlett was so good in
A Good Woman, this peroiod piece may prove to be an excellent vehicle for her. More info can be found at:
