As expected, "La La Land" took home Best Picture... until it didn't.

Hollywood royalty Warren Beatty and Faye Dunaway aka "Bonnie & Clyde" presented the night's biggest prize, and after an awkward pause, it was announced that the front-runner musical had taken home Best Picture. La La Land's producer was almost done with his speech until a bombshell was whispered in his ear, which he then relayed to the audience: The real winner was... Moonlight!

Turns out that Beatty had been given the wrong envelope, as he explained to the crowd; the reason he paused for a moment was that the winner card he took to the stage was for Emma Stone's Best Actress win. Eventually, someone ran out the real Best Picture envelope, and soon enough, director Barry Jenkins and his crew came up on stage to claim the prize. It was one of the most shocking moments in Oscars history, and sure to be talked about for years to come. The fact that the underdog movie won top prize made it all the more unbelievable.
