Jennifer Lawrence was nominated for her first Oscar at twenty, and since then she has balanced the biggest of big-budget franchises, like the “Hunger Games” and the “X-Men” series, with smaller, prestige films, including “Silver Linings Playbook” and “mother!” That has made her perhaps the most famous and the most celebrated actor of her generation. Lawrence has tended to shy away from nudity and sex on film, but in the new “Red Sparrow,” directed by Francis Lawrence, she tackles a role that combines two of today’s most critical issues: Russian espionage and sexual coercion at work. As a frequent target of tabloid journalists, trolls, and hackers, Lawrence is frustrated that so many people still want to punish successful women, but, she tells David Remnick, Hollywood itself is changing; and, despite the likely cost to her career, she intends to spend the next year off the set and working as an activist, speaking to young people about the importance of political engagement.Plus, a look at the lobbyist who helped make Florida one of the most gun-friendly states in America.
