A huge cock up at the Academy Awards where Faye Dunaway read out the wrong winner for Best Picture.
Here's my take on what happened.
Faye Dunaway and Warren Beatty were given the wrong envelope.
Above, you can see Warren Beatty holding an "Actress In A Leading Role" envelope, which had already been won by Emma Stone in La La Land.
You can see the confusion on Warren Beatty's face when he pulls out the card - he actually looks in the envelope again, and appears to look off-stage for help.
Then, after hesitating, he shows the card to Faye Dunaway, who fails to see Emma Stone's name, or perhaps it fails to register, but just sees the words La La Land (1.2 favourite) and reads it out.
The actual winner was second favourite Moonlight.
I happened to read an article last week on the counting process, and one of the facts is that two people have the results, and take separate routes to the ceremony.
Thus there are two copies / envelopes for each category, one is stage left, the other stage right.
It appears to me that the mix-up was that somehow the Best Actress envelope was given to presenters twice.
Not sure why Warren Beatty is being blamed for the error.
