01:00 UTC: The show has begun! Host Jimmy Kimmel is addressing the crowd and television audience. He has already made note of last year's Best Picture announcement mistake; he told tonight's winners not to come up to the stage to accept the Oscar right away. Of course, he is just joking.
00:45 UTC: The 2018 Academy Awards ceremony is about to begin. The event in Hollywood, California, is the biggest night in the American film industry. The National Academy of Motion Picture Arts and Sciences awards Oscars to the year's best movies and movie makers.
Refresh the page for the latest #Oscars90 news.
While we wait for the action to begin, you can read about this year's nominated films here.
Comedian Jimmy Kimmel is this year's Oscars host. He also hosted last year’s event. That is when presenters Faye Dunaway and Warren Beatty famously announced La La Land instead of Moonlight as the Best Picture winner. After the mistake was corrected, Kimmel told television viewers, “I promise I’ll never come back” to host another Oscars.
But Kimmel is back. And organizers are hoping this year's ceremony avoids such a mistake!
