Twist in the plot: The biggest gaffe in Oscars’ history

Barry Jenkins' Moonlight - not, as it turned out, La La Land - won best picture at the Academy Awards in a historic Oscar upset and an unprecedented fiasco that saw one winner swapped for another while the La La Land producers were in mid-speech. Presenters Warren Beatty and Faye Dunaway apparently took the wrong envelope - the one for best actress winner Emma Stone - onto the stage. When they realized the mistake, representatives for ballot tabulators Price Waterhouse Coopers raced onstage to try to stop the acceptance speeches. It was, nevertheless, a shocking upset considering that La La Land came in with 14 nominations, a record that tied it with Titanic and All About Eve.
