Henry Cavill's Superman finally shows up in a new promotional poster for "Justice League". The Man of Steel has been absent from all the theatrical trailers and a bunch of photos of the DC superhero team-up film, but he can now be seen in the newly-unveiled poster looming large over his teammates.

The League looks ready for battle. Ben Affleck's Batman, Gal Gadot's Wonder Woman, Jason Momoa's Aquaman, Ezra Miller's The Flash and Ray Fisher's Cyborg are all striking bold poses in the poster, while Superman can be seen floating behind them and showing off his dauntless look.

It won't be long until "Justice League" hits theaters in the Unites States. The Zack Snyder-directed movie is set for a September 17 release. Snyder directed from a screenplay by Chris Terrio. After the helmer left the project in May following the death of his daughter, Joss Whedon acts as the director of post-production as well as screenwriter for the film's additional scenes and reshoots.

In "Justice League", fueled by his restored faith in humanity and inspired by Superman's selfless act, Bruce Wayne enlists the help of his newfound ally, Diana Prince, to face an even greater enemy. Together, Batman and Wonder Woman work quickly to find and recruit a team of metahumans to stand against this newly awakened threat.

But despite the formation of this unprecedented league of heroes--Batman, Wonder Woman, Aquaman, Cyborg and The Flash--it may already be too late to save the planet from an assault of catastrophic proportions.

The League will face off against Steppenwolf, played by Ciaran Hinds, in the flick. Other cast members include Amy Adams as Lois Lane, Amber Heard as Mera, Jeremy Irons as Alfred Pennyworth, J.K. Simmons as Commissioner James Gordon, Diane Lane as Martha Kent, Connie Nielsen as Queen Hippolyta, Willem Dafoe as Nuidis Vulko and Jesse Eisenberg as Lex Luthor.
