“He gives her cunnilingus and in my opinion, not enough.” So says Rooney Mara in the opening of the eight minutes David Fincher showed to lucky crowds in front of select screenings of Straw Dogs tonight. After nearly a year of films that focus on story without paying much attention to the images, Fincher’s palette blooms like distant heat lightning on a desert horizon; it can be no other director. With every film he grows as a visual storyteller. I can say with certainty that I’ve never seen anything like this. Something savage has been unleashed in the star, Rooney Mara. At their finest, Fincher’s films work best when he has a star who can absorb and thrive on the hardcore focus he dishes out. Jesse Eisenberg did it. Jake Gyllenhaal did it. And now Rooney Mara does it.
