The 89th Academy Awards concluded with the biggest blunder in Oscar history. Presenters Warren Beatty and Faye Dunaway were handed the wrong envelope (the backup for Best Actress) and mistakenly announced 'La La Land' as the Best Picture winner. The producers of 'La La Land' were mid-speech when stagehands and accountants from PwC intervened. Producer Jordan Horowitz famously held up the correct card to the cameras, announcing, 'There's a mistake. Moonlight, you guys won Best Picture.' The confusion was traced back to accountant Brian Cullinan, who was distracted by social media backstage. 'Moonlight' became the first film with an all-Black cast and the first LGBTQ+ themed film to win Best Picture, but the historic moment was largely overshadowed by the chaotic 'Envelopegate' error.
