Sandra Bullock says George Clooney had no time for pranks on 'Gravity' set

sandra-bullock-george-clooney-gravity-venice-film-festival.jpg Sandra Bullock and George Clooney, who have never appeared on screen together before their upcoming release "Gravity," but who are old friends in Hollywood, walked the red carpet together for the Venice Film Festival premiere of their new release.

Speaking to the Daily Mail about Clooney's penchant for pranks on movie sets, Bullock says, "This film was so hard that pranks had no place. There was never down time. How are you going to prank someone who's hanging from a scaffold with 12 wires, rigged up all day? So we had a truce at the very get-go because that just wasn't the place to prank."

"Gravity" tells the story of a medical engineer (Bullock) and a veteran astronaut (Clooney) who must work together to survive after an accident at the space station leaves them adrift. It was written and directed by Alfonso Cuaron ("Harry Potter and the Prisoner of Azkaban," "Children of Men").

"Gravity" opens nationwide Oct. 4.
