The most exciting part of a very dull Oscars ceremony last night was when the wrong movie was announced as the Best Picture winner. Presenters Faye Dunaway and Warren Beatty read out La La Land as the winner, but it turned out Beatty was holding the wrong award envelope — for Best Actress, which Emma Stone had won just prior.

La La Land’s acceptance speeches had to be interrupted to remedy the error. “This is not a joke,” La La Land producer Jordan Horowitz said. “Moonlight has won best picture.”
