IT WASN’T a matter of whether we would get a Justice League movie, really. It was just a matter of when. But with the next Superman film still two years out, it’s swell that close-to-the-vest Warner Bros./DC Entertainment is letting us peek at a few more of its playing cards.

At last, we have confirmation that a stand-alone Justice League is a real thing. And — hit us again, dealer — also the news that “Man of Steel’s” Zack Snyder will direct DC’s attempt to counter the power assembly that is “The Avengers” films.

WB honcho Greg Silverman (official business-card title: president of worldwide production) told the Wall Street Journal blog Speakeasy that his studio has “set plans to make a ‘Justice League’ movie,” the paper reported Sunday evening. (Variety later got its own confirmation.)

There’s no set release date and no set script. What we have, exactly, is the distant but reassuring promise that by the time our next American president is nearing the end of his/her first term, we may nearly have a Justice League film.

Hey, Zack Snyder can only direct these things so quickly.

(Besides, Marvel Studios may only have made a few more billion dollars by then.)

More immediately, in the middle-distance, is the “Man of Steel” sequel that may or may not be released under the title “Batman vs. Superman” in 2016, with Henry Cavill returning as Supes; Gal Gadot donning Wonder Woman’s golden lasso and Aegis bracers; and Ben Affleck trying to prove legions of postadolescent-in-name-only doubters wrong as the franchise’s older, paternal Batman.

Silverman wouldn’t say which “Justice League” members might appear in the film besides the big DC triumvirate. What he would coyly tell the Wall Street Journal is: “It will be a further expansion of this universe. ‘Superman vs Batman’ will lead into ‘Justice League.’ ” (And no, Silverman apparently didn’t explain why he transposed the heroes’ names in the title of Snyder’s 2016 sequel. In this poker game of teasers, was that meant as a “tell,” too?)

Meanwhile, another WB executive, Sue Kroll (official biz-card title: president of worldwide marketing) played her own card, telling the Journal of a possible stand-alone Wonder Woman/Diana Prince film: “With the right script, that could be viable. The world is ready for her.
