She told interviewers that she wanted her character in new sci-fi movie Gravity to be almost "androgynous" in appearance, but Sandra Bullock was all glamour as the flick had its world premiere in Venice last night.
The actress stars alongside George Clooney in the film, which has been picking up high praise from critics.

She stunned in a strapless scarlet gown with black accessories and her hair tied back, while co-star Clooney looked suave as ever in a black tux and bow tie.
The Miss Congeniality actress had told Digital Spy that glamour was definitely not on her mind when she was preparing to take on her role in the new thriller, saying: "The physical aspects were two-fold - one was the core physicality which I needed in order to execute the wire work that was being done, and thank God I did that.
"The other side was what I wanted her to look like, or not look like, as a human being. She had experienced great tragedy, and a loss no-one should ever feel, which was the loss of a child."
She went on: "I wanted her to look as though she's trying to do everything she can to remove anything that would remind her of what she once was, which was a mum. I wanted the body to look almost androgynous."
Reviews have been overwhelmingly enthusiastic thus far, with The Hollywood Reporter writing: "At once the most realistic and beautifully choreographed film ever set in space, Gravity is a thrillingly realised survival story spiked with interludes of breath-catching tension and startling surprise."
