Gravity is a 2013 3D science fiction thriller and space drama film co-written, co-produced, co-edited and directed by Alfonso Cuarón. The film stars Sandra Bullock and George Clooney as surviving astronauts from a damaged Space Shuttle; they are the only actors appearing in the entire film, apart from voice acting.
Cuarón wrote the screenplay with his son Jonás and attempted to develop the project at Universal Studios. After the rights to the project were sold, the project found traction at Warner Bros. instead. 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. It got a wide release in the United States and Canada on October 4, 2013.
