During the run up to the 2017 Oscars, there were two clear stand-outs for who would win best picture. It would either be La La Land, a musical about how great Old Hollywood was (and since this is Hollywood giving the award, you know that's gonna get on their good side) or Moonlight, a black-led introspective LGBT film about a young man growing into his own. Both films had their supporters, and La La Land certainly had its detractors. Most people who were against it thought La La Land would win because, well, it was basically an anthem about how awesome Hollywood was, and what does Hollywood love more than praising itself? Nothing.
Then came the night of the awards and Best Picture went to … La La Land. Naturally. The cast and crew of L3 (as the kids call it) rushed the stage and thanked the Academy, their parents and then … producers for the Oscars rushed the stage. Hold on. Something was going down. There had been a mistake. It was actually … dun dun dun … Moonlight that had won. What was going on? Turned out that there's two copies of every award envelope, and the wrong one was given to the host. They got the envelope for Best Actress, which had gone to Emma Stone in La La Land, and the announcers were confused. But actually, Moonlight won Best Picture.
Well, in truth, we all won, because this was basically the most entertaining thing to ever happen at the Oscars.
