First "Justice League" Film Plot Details, Logo Revealed | "Justice League" Movie's Main Villain Confirmed | Willem Dafoe's "Justice League" Character Revealed | First Look at "Justice League's" Upgraded Batmobile, More New Bat-Tech Revealed | "Justice League" Aims to Be 'More Inclusive,' Less Dark than "Batman v Superman" | "Batman" Movie Update: Affleck Has 'Highest of Standards' for Solo Film

There's still nearly a year and a half before the scheduled release of the "Justice League" film, but Warner Bros. has clear aims on getting some positive word out already. The studio held a set visit last week for the DC Comics-based film, with press including CBR News getting an early look at the movie.

Along with that, the first plot synopsis for "Justice League" has been released, which, while not divulging any unexpected details, gives a brief outline of what to expect from the upcoming superhero team-up:

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.

Directed by Zack Snyder, this marks the big screen debut of the Justice League, featuring an all-star lineup: Ben Affleck, Henry Cavill, Gal Gadot, Jason Momoa, Ezra Miller and Ray Fisher.

"Justice League" is a direct follow-up to this year's "Batman v Superman: Dawn of Justice," which somewhat underperformed at the box office -- it grossed $872.7 million worldwide, an impressive number but still below the $1.14 billion counting earned by "Captain America: Civil War" -- and received a mostly negative response from critics and a decidedly mixed reaction from fans. Warner Bros. appears intent on changing the "Justice League" narrative, and that's evident even from the short plot outline.

Declaring right at the star that Bruce Wayne is "fueled by his restored faith in humanity," there's already a clear distinction in tone between "Justice League" and "Batman v Superman," the latter of which was frequently criticized for being overly dark and grim. In "BvS," Batman was driven by revenge and a desire to (violently) end what he saw as a major threat poised by Superman -- here, he's apparently inspired by Superman, and operating as a proactive hero looking to form a super-team.

During the set visit, Affleck -- who debuted as Batman in "Batman v Superman" -- shared with reporters insight into his take on a more hopeful Dark Knight.

"He's a little bit more sardonic, a little more irony," Affleck told reporters. "He's a little more of a man on a mission this time. As opposed to, he was so full of anger because of what happened at the Black Zero Event. That sort of rage that possessed him. And now he's on a mission to get this group together; to constitute this League. But more of that sort of Bruce Wayne, wry, ironic gallows humor comes out. He's not like a 'haha' jokey, but that sort of stuff comes out a little bit. A bit of his darker humor is present."

At the set visit, it was confirmed that, as had been previously speculated, New Gods character Steppenwolf would be the main villain of the film -- and likely leading the "newly awakened threat" mentioned in the synopsis.

Along with the synopsis, the official logo for the "Justice League" film has also been released:

Though distinct from past iterations, the star between the "I" and the "C" serves as a callback to the classic Justice League comic book logo, which featured multiple stars:

Written by Academy Award-winner Chris Terrio, "Justice League" is scheduled for release on Nov. 17, 2017. Keep reading CBR for much more from the "Justice League" set visit.
