Production on "Justice League: Part One" is officially underway, and fans have already gotten quite a few behind the scenes looks at what to expect when the flick finally hits theaters late next year. Now, star Henry Cavill has also shared a sneak peek of his new Superman duds for the film, foretelling a more somber return for the Man of Steel.

Cavill took to Instagram this week to reveal a snippet of his Superman costume, and this time, it looks a bit different from the iconic red, blue, and yellow number that fans have come to associate with the hero. The super tight closeup shot shows very little of his look, but the new color scheme is unmissable: this time, Supe will be sporting solid black.

That likely means that "Justice League" will closely follow the plot of the "Death and Return of Superman" comic series from the 1990s, which saw the Man of Steel return from his demise wearing an all-black suit. And since (SPOILER ALERT for those who have yet to see "Batman v Superman") Cavill's character died at the end of "Batman v Superman: Dawn of Justice," it would make sense to resurrect him with this new costume.

Of course, there's still a possibility that Cavill may have just been getting a little creative with his Instagram filters, and the suit actually isn't black at all. We'll have to wait until someone else from the production -- perhaps even the actor himself -- shares some more intel from the set before we know more.

"Justice League: Part One" is due in theaters on November 17, 2017.
