Felicity Jones struggled with Ruth Bader Ginsburg's Brooklyn accent in upcoming "On the Basis of Sex"

English actress Felicity Jones told Yahoo Entertainment at CinemaCon that the biggest challenge of playing Justice Ruth Bader Ginsburg was nailing her Brooklyn accent. Jones recalled that Ginsburg told her, "you speak the Queen's English and I'm a girl from Brooklyn, how's that going to work?" Jones however, says she met the challenge and "just went for it."
