Faye Dunaway and Warren Beatty took the stage to announce best picture... "La La Land." The producers and cast of the heavily favored film took the stage, and several of them spoke. But then, with the throng still onstage, producer Justin Horowitz — who had already given his heartfelt thanks — returned to the microphone and announced that there had been a mistake. In fact, best picture had not been won by La La Land, but by Moonlight, a beautiful, moving and very inexpensive independent coming-of-age drama.
