Sandra Bullock is getting raw and real for her upcoming flick, "Extremely Loud & Incredibly Close."
For her first film project in over a year and a half, Bullock chose the Warner Bros. flick — costarring Tom Hanks — based on author Jonathan Safran Foer's acclaimed novel. She'll appear in the film as the mother of a nine-year-old boy, Oskar, who loses his father on 9/11.
