Sandra Bullock: 'Gravity' at Comic-Con!

Sandra Bullock is red hot while attending a preview for her upcoming flick Gravity during the 2013 Comic-Con International at San Diego Convention Center on Saturday (July 20) in San Diego, Calif.

This was the first time that the 48-year-old actress attended the convention and was joined by the flick’s director Alfonso Cuaron and producer David Heyman.

“They had me strung up on wires for eight to nine hours a day,” Sandra shared about filming the flick. “If you were in pain, either use it, or, I learned how to meditate. Alfonso gave me boxes of CDs with sounds … anytime I was in a place, he would just play music for me.”

She added, “It sounded very Cirque du Soleil for me. I just wanted my body to get my core to accomplish whatever they wanted me to do…. I wanted the look to be as androgynous as I could get her.”

FYI: Sandra is wearing a Roland Mouret dress.
