Update: The image may be from Batman vs. Superman.
The Justice League set images reveal Henry Cavill back in the red and blue costume. Cavill recently teased the Superman black costume for Justice League, which is thought to be similar to the "return of Superman" comic book version.
Henry Cavill can also be seen in the Justice League set images sporting the classic Superman curl, with green screens in the background which is used for CGI.
The Instagram user notes, "Superman gives the best hugs!"
Henry Cavill is currently filming Justice League in the UK.
Last we saw of Henry Cavill and Superman, the last son of Krypton had fallen in battle while defending humanity against Doomsday in Batman v Superman: Dawn of Justice. Superman sacrificed himself to stop the Kryptonian hybrid creature with the help of fellow Justice League members Batman and Wonder Woman. Superman was buried in Smallville; however, as we all know -- you can't keep a good Man of Steel down.
"Justice League" has a November 17, 2017 release directed by Zack Snyder starring Ben Affleck as Batman, Henry Cavill as Superman, Gal Gadot as Wonder Woman, Jason Momoa as Aquaman, Ezra Miller as The Flash, Ray Fisher as Cyborg, J.K. Simmons as Commissioner Gordon and Willem Dafoe as an Atlantean.
