Not since a Chicago newspaper headlined “Dewey Defeats Truman” has there been a massive public screw-up on the order of what happened at the Oscars on Sunday night. But it’s an ill wind that blows nobody some good, and the huge embarrassment for Warren Beatty, Faye Dunaway and the academy may turn out to be a good thing for the Oscars. 

For if having a debacle like the two presenters announcing the wrong winner before millions of viewers in 225 countries does nothing else, it proves the lasting watchability of live television.

Yes, even in this age of presumed digital safeguards everyone got to see the “La La Land” entourage troop joyously on stage and then retreat in disarray in the face of the equally shocked “Moonlight” folks when the error was discovered. Truly, if surrealist Luis Bunuel had had a writing credit on the program he could not have done it any better.

Finally, too, it was good to see the Academy do what film festival juries often do, which is judiciously split their votes between many worthy contenders.

Having given “La La Land” six victories, including lead actress, director, original song and original score — twice as many as its nearest rival — it decided that giving a little more love to “Moonlight,” already with two Oscars, was the thing to do.

The fact that it came with the last and biggest award — and in such shocking fashion — made it all the more astonishing.

Signs of this had appeared earlier, when “La La Land” lost three key races it might have won: editing went to “Hacksaw Ridge,” original screenplay went to “Manchester by the Sea” and sound editing went to “Arrival.” The feeling of a sweep was never in the air.

And “Moonlight” turned out to be a very apropos choice for several reasons. For one, even though its coming-of-age story of a gay young black boy with a crack addicted mother does not sound like the kind of thing that would make old-school moguls the Warner brothers or Harry Cohen stand up and cheer, in fact the enormous feeling of transcendent well-being that you feel by the film’s close put it closer in line with traditional Hollywood movies than might be imagined.

And this turned out to be a year when sending a message was clearly on voters’ minds, a trend exemplified by giving the foreign language award to Iran’s Ashgar Farhadi and his “Salesman” at least in part, or so it seems, to protest the proposed presidential ban on travelers from seven Muslim countries. So giving best picture to a film that celebrates the beauty of being who you are was something that Academy members could not resist doing.
