At the 89th Academy Awards , presenters Faye Dunaway and Warren Beatty announced that '' La La Land '' was the winner of Best Picture . However , they had mistakenly been given the envelope for Best Actress , a category in which Emma Stone had won for her role in '' La La Land '' several minutes prior . When the mistake was realized , Horowitz rushed to the microphone to announce '' Moonlight '' as the correct winner , taking the letter from Warren Beatty and then presented the Oscar to the winning producers . This occurred after PricewaterhouseCoopers representatives appeared on stage to discuss the mistake with the team from '' La La Land '' and Warren Beatty
