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, and then graciously 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.
