LOS ANGELES (AP) — Emma Stone sang and danced her way to a best-actress Oscar for "La La Land," elevating the once struggling actress with roots in community theater to the heights of Hollywood. Stone's victory on Sunday night was the sixth Oscar earned by the musical set against a Los Angeles backdrop. Once there, she endured starts and stops before breaking through in 2010 with the teen comedy "Easy A." Except it was a mistake that lasted for about 2 ½ minutes until "Moonlight" was announced as the real winner.
