SAN DIEGO - Sandra Bullock has landed at Comic-Con.
The actress came to the pop-culture convention for the first time Saturday to discuss the new film "Gravity," in which she and George Clooney play astronauts floating through space.
Director Alfonso Cuaron said the two Oscar winners comprise the entire cast.
Bullock spent more than six months physically preparing for the role, which required her to spend dozens of hours in a 9-by-9 foot cube that simulated zero gravity. Other shots required her to be "strung up from 12 wires 18 hours a day."
Cuaron said, "It was a very intense experience for Sandra."
After promoting the film, Bullock said she planned to stroll the Comic-Con convention floor trying to "get free stuff."
"Gravity" opens in October.
