Currenlty nothing has even been set in stone, but at a recent convention this poster was displayed in order to attract toy distributors and other movie tie ins (i.e. fast food restuarants, video games, etc.)
So without a scene filmed and without an actor having officially signed on (although Tobey Maguire and Kirsten Dunst are attached, along with director Sam Raimi, according to the IMDB website), this poster was released.
And I'm not going to lie to you. I am already really excited about this film.
