Gravity is a 2013 American 3D film co-written, co-produced, co-edited and directed by Alfonso Cuarón. The film stars Sandra Bullock and George Clooney as surviving astronauts in a damaged space shuttle.
Cuarón wrote the screenplay with his son Jonás and attempted to develop the project at Universal Pictures. After the rights to the project were sold, the project found traction at Warner Bros. instead, and the studio approached multiple actresses before casting Bullock in the female lead role. Robert Downey, Jr. was also involved as the male lead before leaving the project and being replaced by Clooney.
Gravity opened at the 70th Venice International Film Festival in August 2013. Its North American premiere was three days later at the Telluride Film Festival.
