Associated Press LOS ANGELES — “Moonlight” won the best picture trophy at the Academy Awards in a historic Oscar upset that followed Warren Beatty at first reading the wrong winner. Shock and chaos spread through the Dolby Theatre when producers of “La La Land” were stopped in the middle of their acceptance speeches to be informed that Beatty had incorrectly read “La La Land” as the winner. “I wasn’t trying to be funny,” Beatty explained, saying he had seen the name Emma Stone from “La La Land” when he opened his envelope.
