About That 'Justice League' Post-Credits Scene and What It Means Going Forward

The movie ended with Wonder Woman, Batman, Superman, Cyborg and The Flash defeating CGI monstrosity Steppenwolf, before going off on their separate journeys for more standalone films. While Steppenwolf's connection to Darkseid - as well as that nightmare vision from "Batman v. Superman" - signal he'll show up eventually, the last stinger also teased another group of Big Bads.

Though the mid-credits scene showing Flash challenging the man from Krypton to a race was cute, it's the other one involving Lex Luthor (Jesse Eisenberg) that got fans at this reporter's screening pumped. After escaping from prison, Luthor took off to some Monte Carlo-looking locale, where he's been chilling on a yacht with a few scantily-clad female bodyguards. He's joined by a heavily armed masked man name Slade, played by a white-haired Joe Manganiello.

Slade is Slade Wilson, AKA Deathstroke, a master assassin and all-around bad guy in the DC world. Lex's idea, after learning of the Justice League, is for the villains to form "a league of our own."

Not to be confused with the amazing 1992 movie starring Geena Davis, Luthor's most likely referring to the Injustice League (or similarly-themed Legion of Doom). In the comics - and there are a lot of them to draw from - this evil version of the super-friends has included villains like The Joker, Poison Ivy, Killer Frost, Harley Quinn, Catwoman, Reverse Flash, Black Manta and Captain Cold at one point or another.

The big question now: When will we see them all in action?

As it stands, the next four movies in the DC universe with release dates are "Aquaman" on December 21, 2018, "Shazam" with Zachary Levi on April 5, 2019, "Wonder Woman 2" on November 1, 2019, a standalone "Cyborg" film on April 3, 2020 and "Green Lantern Corps" on July 24, 2020.

Other planned films without dates include a "Deathstroke" film, "Batgirl" from Joss Whedon, "Flashpoint," "Gotham City Sirens," another "Suicide Squad" film, a Harley Quinn and Joker film, "Justice League Dark" and a Matt Reeves' "The Batman." A "Justice League" sequel was originally supposed to come out in 2019 too, but it's also been moved back to a TBD date.

Basically, it doesn't even seem like Warner Bros. fully knows what's coming when. While Manganiello's character was supposed to be the main villain in "The Batman" -- in addition to his standalone film -- it's likely the rest of the group will be introduced in their superhero's solo films first, before joining together in another team-up flick in the undetermined future. And with Darkseid looming behind everything going on as well, the Justice League will certainly be busy for a while.
