One of either Cullinan or Ruiz, but probably Cullinan, did not dispose of the duplicate and realised too late...ironically given their interview 48 hours before about what would happen if name read out was ever wrong...they claimed they would know when wrong name was announced and go on stage asap (as they memorise the winners).
Brian did do that, along with the correct envelope, but IMHO too late. Someone backstage also saw Warren had the best actress duplicate.
The only question is...why it took them so long to spring into action once the wrong film was announced, a long time being at least two minutes and allowing the Lala speeches to start.
You see Brian go on stage along with a headphones producer but we're onto the third speech by then. Emma Stone mouths oh my God. Third guy falters, says didn't win BTW.
At that point Jordan steps up and because neither Brian, Producer nor Jimmy have taken to the mike, he snatches card out of Beatty's hands for a close-up that No, not kidding.
It was a clusterfuck but I really don't think they were going to cover it up and go with lala, nor that it was for publicity, I just think there was a dazed, confused, panicky frozen rabbits in headlights reaction.
I really wish Warren had been there with Annette, then he could have vocalised what was wrong. You see it non verbally but Faye, thinking it was for tension, says "you're impossible" before blurting.
She said later something vague, along the lines of it being quick and "the card read that way".
Jordan had the card with Emma Stone on it so presumably Faye just focussed on the La La bit.
I cannot believe they just took a punt on the odds.
Really wish that Warren had said "Best film Oscar goes to...Suicide Squad. Now, I have been stalling for a while now in the hope that someone would realize I have the wrong envelope. Can we have another drum roll please?"
He did not convey to Faye what was happening.
The memes are good though.
At least it gave Jimmy an out in terms of not being asked back. It will give host material for next year's.
Still not my favourite Oscar moment though..that would be John Travolta announcing Idina Mendel as Adele Dazeem, bless him.
