LOS ANGELES (AP) — Oscar winner, take two. 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.
