The April 2006 issue of Total Film features a blurb about The Black Dahlia, which lists the film’s release date in the UK for November 11, 2006. According to Total Film, Maggie Gyllenhaal was the first choice to play Kay Lake, the role that Scarlett eventually landed. Of Johansson, De Palma is quoted saying: “I’d say she’s one of the finest actresses working today, but I think that underestimates her talent.” ( source )

Also, Josh Hartnett recently spoke to ninemsn and he was asked of his relationship with Scarlett.

Josh, you are soon going to be starring in The Black Dahlia with the very sexy Scarlett Johansson. Can we expect to see a little bit of on screen sizzle?
Hartnett: “Probably yeah. She and I, and Hilary (Swank) and I, both have some full-on scenes.”
