When "Justice League" arrives this November, it will unite the heaviest-hitters in the DC Universe. Superman (Henry Cavill), Batman (Ben Affleck), Wonder Woman (Gal Gadot), Aquaman (Jason Momoa), Flash (Ezra Miller) and Cyborg (Ray Fisher) will round out the initial "League" line-up -- but they're missing someone.

That someone is Green Lantern, and he's not in that lineup because Warner Bros. has yet to cast someone to play Hal Jordan (or any of the other Green Lanterns, either). As more and more time passes without a Green Lantern announcement, more people wonder when we'll hear anything about DC's premier cosmic hero.

Henry Cavill, who plays Superman (a.k.a. Kal-El), knows this and has started an Instagram series titled "Kal looking for Hal." The title is short and the captions offer no further hints about Green Lantern or Justice League or, well, any DC movie.

It's possible, and most likely, that Cavill is just having a bit of fun on Instagram after coming up with the phrase "Kal looking for Hal." Still, it's been a year and a half since WB announced the "Green Lantern Corps" movie, and there have been no major announcements about the film since. The film is right now slated to hit theaters in 2020, which is still a ways off, but Green Lantern himself might appear in "Justice League 2."

Of course "Justice League 2's" release date is currently unknown as well. It was originally slated for 2019, but it was revealed that filming of the sequel was pushed back to accommodate Ben Affleck's solo "Batman" film. More recently, "The Batman" hit a speedbump when Affleck stepped down as director, but now Matt Reeves is on board. "The Batman" was originally slated to begin shooting in the spring, but it's not yet known if this change behind the scenes has slowed down production.
