Stone has high praise for extras

Sharon Stone has praised the talented extras in her latest movie Bobby - and wishes there was an accolade equivalent of an Academy Award for the budding stars.

The Casino beauty appears alongside William H Macy, Heather Graham, Christian Slater and Demi Moore in the Emilio Estevez-directed movie about the 1968 assassination of US Senator Robert F Kennedy.

Stone says: "I wish there was an Oscar for extras. I'm not even joking because the performances they gave are so compelling and so rich and so deep."
