Los Angeles: Legendary actor Warren Beatty's son Stephen Ira has defended his father's mix-up while presenting the best picture Oscar at this year's Academy Awards, saying "mistakes happen at live shows".
The bizarre incidents took place at the end of the gala night when "La La Land", which won six trophies including best director and actress, was incorrectly declared the best picture winner by Beatty and Faye Dunaway at the ceremony.
"Proud of my dad for his grace! It's live, stuff happens. Showbiz!" Ira tweeted.
In a later tweet, he wrote, "I think it was just a mix up! Mistakes happen, especially in a live show."
Beatty was announcing the final award onstage with Dunaway, in a "Bonnie and Clyde" reunion, when he seemed to pause after opening the envelope.
He exchanged a look with Dunaway, who then took the card and announced "La La Land" as the winner.
However, during the their victory speech, the musical's one of the producers, Jordan Horowitz, realised the mistake and announced that the award actually belonged to "Moonlight".
