The Oscars were pretty unremarkable. As expected, La La Land scooped numerous awards, including Best Cinematography, Best Original Score, and Best Production.

But then, something spectacular happened: Warren Beatty and Faye Dunaway — through no fault of their own — announced that Damien Chazelle’s film had won Best Picture.

As we all know, Barry Jenkins’ Moonlight was the real winner, leading to an awkward exchange of trophies on-stage and speculation over why the mix-up happened.

Appearing on The Graham Norton Show, Beatty called the event ‘chaos’ while defending his part in the incident and Dunaways.

“I thought well, maybe this is a misprint,” he said. “And then, I shouldn’t foul up the show just because someone made a little error.”

Asked whether he handed the letter to Dunaway to move fault to her, Beatty responded: “My instructions were to take the envelope when I walked out. I couldn’t have it before that. And then I go out, and then I say something, and then I open the envelope and then I give it to Faye and she then says what it says.”

In a final comment, Norton joked how the event was “all anyone could talk about,” to which the actor quipped: “No, that’s not true, people talk about themselves.”
