Rupert Everett claims Hollywood star Sharon Stone is deranged. The MY BEST FRIEND'S WEDDING actor insists being slightly mad is a necessary quality for surviving in the film industry. The British actor discusses Basic Instinct star Stone and other A-listers, including Julia Roberts, in his autobiography RED CARPETS AND OTHER BANANA SKINS. He writes, "Saying that Sharon is unhinged is not rude; being unhinged is a prerequisite for being in showbusiness. "It is to their credit that these women are mad and tough and incredible. "Sharon Stone is an extraordinary character, extremely intelligent, totally controlling, really fun but... unhinged. And that's kind of fabulous."
