It was one of the most awkward moments in the history of the Oscars, of television, in entertainment, heck maybe in American history.

And somehow Warren Beatty, Hollywood91裸聊视频檚 ultimate smooth leading man, was at the centre of it.

The producers of 91裸聊视频淟a La Land91裸聊视频� were nearly done with their acceptance speeches for Best Picture, the Oscar broadcast91裸聊视频檚 credits sequence about to roll, when a stir of whispers began on stage. Moments later 91裸聊视频淟a La Land91裸聊视频� producer Jordan Horowitz returned to the microphone and said 91裸聊视频淢oonlight won Best Picture91裸聊视频� and insisting that 91裸聊视频渢his is not a joke.91裸聊视频�

The collective jaw of the crowd at the Dolby Theatre 91裸聊视频� and of America 91裸聊视频� remained dropped long after they became convinced it was no joke, but what academy historians later called an apparently unprecedented Oscar error.

Beatty returned to the mic and amid silence, explained that he had opened the envelope and he was confused when it read 91裸聊视频淓mma Stone, La La Land.91裸聊视频� He had shown it to co-presenter Faye Dunaway briefly, as though he wanted her to read it, which she did, apparently assuming the Emma Stone part was off but the 91裸聊视频淟a La91裸聊视频� part correct.

91裸聊视频淚t91裸聊视频檚 one of the strangest things that91裸聊视频檚 ever happened to me,91裸聊视频� Beatty said backstage. 91裸聊视频淭hank God there were two of us up there,91裸聊视频� Dunaway responded.

The actress then asked Beatty, 91裸聊视频淲ho else should I tell?91裸聊视频�

91裸聊视频淓verybody,91裸聊视频� he said.

At that point, a security guard tried to take the real envelope and Beatty said, 91裸聊视频淪ecurity is not getting this. I91裸聊视频檓 giving it to (Moonlight director) Barry Jenkins at a later time.91裸聊视频� Beatty also refused to show it to anyone else.

ABC News, tweeting about the ceremony broadcast on its network, said the envelope held by Beatty read, 91裸聊视频淎ctress in a leading role.91裸聊视频� A close-up photo of Beatty onstage verified that.

The mistake was being investigated by the academy, which had no immediate comment Sunday.

PwC, formerly known as Price Waterhouse Coopers, is the accounting firm that counts votes and provides winner envelopes for the Oscars and has done so for more than 80 years.

When the firm91裸聊视频檚 representatives realized the mistake, they raced onstage to right it, but too late, officials told The Associated Press.

The result was a bizarre scene with the entire cast of both movies standing together on stage exchanging sympathetic awkward stares and hugs.

The crowd had to rouse itself from its stunned stupor to try to give 91裸聊视频淢oonlight91裸聊视频� its just due for winning the big award. And as the credits rolled, usually bringing sweet relief after a long night, people appeared hesitant to leave in their disbelief.

91裸聊视频淚t made a very special feeling even more special, but not in the way I expected,91裸聊视频� a bemused Jenkins, co-writer and director of 91裸聊视频淢oonlight,91裸聊视频� said backstage.

91裸聊视频淭he folks at 91裸聊视频楲a La Land91裸聊视频� were so gracious,91裸聊视频� he added. 91裸聊视频淚 can91裸聊视频檛 imagine being in their position and having to do that.91裸聊视频�

Filmmaker Kenneth Lonergan, who won a best screenplay award for 91裸聊视频淢anchester by the Sea,91裸聊视频� cracked wise backstage: 91裸聊视频淚t turns out that we actually won best picture, which we91裸聊视频檙e really happy about,91裸聊视频� he said.

The ceremony91裸聊视频檚 chaotic scene immediately raced to the top of all-time Oscar moments, far more stunning than the nude man who raced across the stage in 1974 as part of the 91裸聊视频渟treaking91裸聊视频� fad.

And it immediately evoked Steve Harvey91裸聊视频檚 recent gaffe of naming the wrong Miss Universe winner.

The Miss Universe Twitter account quickly let the Oscars know they felt their pain.

91裸聊视频淗ave your people call our people, we know what to do,91裸聊视频� the tweet read.

That was the beginning of a Tweet pile-on that may be the biggest of all time, with many declaring that 91裸聊视频淟a La Land91裸聊视频� won the popular vote while 91裸聊视频淢oonlight91裸聊视频� won the electoral college.

But this stage, and this audience, were far, far bigger and are likely to last far, far longer in collective memory.

91裸聊视频榃e thought it was a joke91裸聊视频�: Canadian winner for Arrival

Montreal sound editor Sylvain Bellemare has an epic memory to accompany his Oscar win for 91裸聊视频淎rrival.91裸聊视频�

The Canadian was still in the Dolby Theatre on Sunday night as Warren Beatty and Faye Dunaway wrongly announced 91裸聊视频淟a La Land91裸聊视频� as best picture. Bellemare said it was 91裸聊视频渁ll very embarrassing91裸聊视频� as producers scrambled on stage to reveal that 91裸聊视频淢oonlight91裸聊视频� was the true winner.

91裸聊视频淚t was astonishing for like 15, 20 seconds. I think we thought it was a joke and no, it was real,91裸聊视频� Bellemare said by phone from Los Angeles after the show had ended.

91裸聊视频淏ut yet people were really happy I think because 91裸聊视频楳oonlight91裸聊视频� is a fantastic film that deserves so much,91裸聊视频� he added.

91裸聊视频�91裸聊视频楲a La Land91裸聊视频� is a great film, too, but it already has a lot of love and box office since it started and having 91裸聊视频楳oonlight91裸聊视频� triumph, it91裸聊视频檚 perfect.91裸聊视频�

The accounting firm PwC, which oversees the counting of the Oscar ballots, said early Monday that Beatty and Dunaway had been given the wrong envelope.

Bellemare said 91裸聊视频渁t the end, things went as they were supposed to be.

91裸聊视频淚t was a weird feeling91裸聊视频�. It was something awkward but those things happen and at the end, at least we got the real winner onstage.91裸聊视频�

Bellemare won the Oscar for best sound editor in a field that also included teams from 91裸聊视频淒eepwater Horizon,91裸聊视频� 91裸聊视频淗acksaw Ridge,91裸聊视频� 91裸聊视频淟a La Land91裸聊视频� and 91裸聊视频淪ully.91裸聊视频�

91裸聊视频淭here are so many people behind this prize. It91裸聊视频檚 a collective prize and I was so proud for them and for us.91裸聊视频�
