Jennifer Lawrence's friends would never speak to her again if she adopted a method acting approach.<br /><br /><br /><br />The 27-year-old actress was mortified when director Francis Lawrence urged her to keep the Russian accent she adopted for her role as ballerina-turned-spy in 'Red Sparrow' outside of filming because she knew her pals wouldn't be impressed.<br /><br /><br /><br />She said: "For two weeks before the movie, Francis would say, 'You should talk in the accent at home. Stay in the accent and talk to your friends in the accent.'<br /><br /><br /><br />"I said, 'Francis, I don't have those kinds of friends. They would never call me again.' "<br /><br /><br /><br />Jennifer spent several months working on the accent and though it was tough, it was an essential part of her preparations.<br /><br />
