“Today, humanity is just one misunderstanding, one miscalculation away from nuclear annihilation.” — U.N. Secretary-General António Guterres, speaking at a U.N. conference on the non-proliferation of nuclear weapons.

Oh, good. I’ve often wondered what it would take to put an end to the proliferation of dumbass superhero movies. A global thermonuclear holocaust might just get ’er done.

Or maybe we just need the right supervillain.

It wasn’t the Joker, the Penguin, or the Riddler who croaked “Batgirl” in her crib. No, the killer was the Green Eyeshade at Warner Bros-Discovery-HBO Max p/b AT&T, who discovered — with tens of millions already pounded down this particular Bat-hole — that writing off a made-for-streaming Bat-flick on the conglomerate’s Bat-taxes would not be at all, well … batty.

Industry insiders cite two changes between concept and execution. The first, in ownership, makes this one-time “purchase accounting maneuver” possible, as long as the movie is never released in any way, shape, or form; and the second, in strategy, aims to once again give theaters a head start over streaming as in days of yore.

With a budget made for television, “Batgirl” apparently began life as a B movie in more ways than one. But it can’t be a net positive when the entertainment press is quoting sources as saying that “the film tested once, and the result wasn’t that bad. …”

Too bad for TV? Have these people seen TV?

But when studio CEO David Zaslav tells investors in a second-quarter corporate earnings call, “We’re not going to put a movie out unless we believe in it. And that’s it,” well … piss on the fire and call in the bats, son. If a cameo from Michael Keaton can’t save you, you’re fucked.

Speaking of fucked, how many of you have bomb shelters? Raise your hands … yes, you there, crouched under your desks as if we were all reliving Those Fabulous Sixties.

Which we very well may be, if you listen to the U.N. secretary-general.

“The clouds that parted following the end of the Cold War are gathering once more,” Guterres warned in his remarks to the 10th Review Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons.

“We have been extraordinarily lucky so far. But luck is not a strategy. … Eliminating nuclear weapons is the only guarantee they will never be used.”

Yeah, well, good luck with that, Tony ol’ tiger. We can’t even cut back on “Spider-Man” movies.

While we’re debating whether “The Sandman” is true to Neil Gaiman’s original vision, you can bet your Batarang that some miscreant is trying to steal a tactical nuclear weapon from the Russkies, hoping to vaporize a hospital full of nuns, widder women, and crippled children in Ukraine, and then sit back and watch the fun.

The subsequent tit for tat as old scores get settled would quickly strip the planet of its tits, and also its tats. Anyone who can swing a bat (har de har har) will be stepping up to the plate, and the game will not be called on account of accountancy. Not even Michael Keaton can save us.

The good news is, this will make for some spectacular TV. The bad news? It will be on every channel at once. Welcome to Fyou Island, folks.

Not everyone will get voted off the isle, of course. There will be survivors, in remote spots like Tierra del Fuego. And people being what they are, some bored techie-turned-sheepherder in the former factory town of Rio Grande will eventually link one of the locally produced netbooks, powered by a solar panel, to the scattered strands of the once-mighty Internet.

Of an evening, weary of sheep, he will follow this thread, and then that one, and who knows? He might even unearth the digital archives of Warner Bros-Discovery-HBO Max p/b AT&T, buried deep beneath the glowing remains of Tinseltown in a blastproof vault.

Maybe he stumbles across that unfinished “Batgirl” movie, with its Latina star, and watches it.

“Hijo de la chingada,” he will mutter to himself. “This sucks.”
