Sandra Bullock longed for a juicy part like her role in 'Gravity'.

Bullock admits struggled seeing top male actors like her co-star George Clooney consistently landing parts with depth and felt there was a lack of similar roles for actresses, and so she jumped at the opportunity when offered the role of Dr. Ryan King in the new space epic.

"I was always longing to do, emotionally and physically, what my male counterparts always got to do. I just felt envious every time I saw a movie that I was in awe of and it was usually a male lead. And those kinds of roles weren't available. They just weren't being written she says.

"But in the last couple of years, things have shifted. And then, there's the fact that Jonas and Alfonso [Cuaron] wrote this specifically as a woman. It wasn't an afterthought. I think it was the integral part of the story. I don't want to say that's revolutionary, but it's revolutionary. And the fact that a studio, on blind faith, would fund something as unknown as this is revolutionary."

In the si-fi, Bullock plays a medical engineer sent on a deep space mission with space veteran Matt Kowalsky (Clooney), but the pair find themselves wandering aimlessly in space when their shuttle is damaged.

The Oscar-winner says she was honoured to land the role and gave her all to the part during filming.

"To be able to be the person to do it is beyond humbling. It makes you realize, 'I have to step up and be the best version of myself, so that whatever is asked of me, I can produce.' So, every day, I'm so grateful." she added to Collider
