Most people forget that Sandra Bullock has already won an Oscar, especially considering that most of the public views her as America's Sweetheart or as a comedic actress over a dramatic actress. Sandra herself has been promoting her new film 'Gravity', and admits that she didn't feel worthy of her Oscar when she received it for 'The Blind Side'.

She explains, "What [winning an Oscar] does do is it makes you realize how hard you have to work to earn it. I didn't feel worthy of it when I got it, so I thought, 'Okay, I'm going to spend the rest of my life earning it, but having a really good time in the process as well.'"
She's certainly trying her best to earn it in films like 'Gravity', which has been rave review after rave review coming out of Venice and Toronto. Sandra does admit that making the film was more isolating, explaining, "It was lonely, but in the best way. I don't know any other way to say it. It was frustrating, it was painful, it was isolating. After a while you just get used it, you wanted to kill Alfonso regularly, and I used that as well. So all your hate and your anger and your rage you just give forth in your work and you hope it translates on the screen."

George Clooney also stars in Gravity
Gravity is already set for release in October, and pundits are calling it a sure-fire lock for several Oscars, including a Best Actress nomination for Sandra Bullock, Best Director for Alfonso Cuaron, and several other technical achievements.
