With 24 Grand Slam titles, an Olympic gold medal, and over 1,000 singles match wins, the tennis phenom Novak Djokovic has a storied legacy. But he wasn’t always widely lauded. Even as a champion, the Serbian player was seen as a “party crasher” and an “unwelcome intruder” who pushed into the rivalry between Roger Federer and Rafael Nadal. A new documentary from the director of The Last Dance peers into the psyche of the unrelenting athlete, examining how his childhood in war-ridden Serbia shaped his brash persona and guided him to greatness, while also making him comfortable with conflict (see Djokovic’s 2022 deportation ahead of the Australian Open, caused by his refusal to be vaccinated for COVID-19). “You need to be elegant and sophisticated to play the game, and you need to be the chosen one,” his wife Jelena Djokovic said. “Novak was not the chosen one.” Now nearing the final chapter of his career, the athlete finds himself reckoning with a new challenge: when to stop. —Maggie Turner
