Warner Bros. apparently showed off a screening of the Justice League movie last night.

Users on Twitter are reporting they have seen the movie, and other users are also reporting they have friends that have seen the film.

Sorry, no Justice League spoilers have hit the net, but it's been said the movie is amazing.

Update: It's further said that a Superman fan that was not happy with Man of Steel or Batman vs. Superman loved Justice League, so take that for what it is worth.

The attendees had to sign a non-disclosure agreement, which means if they get caught revealing information, they can get sued.

That said, eventually as we get closer to the November release of the Justice League movie, WB will have screened it more times, and you can expect spoilers to leak out.

I've now heard from three people and one friend about this evening's JUSTICE LEAGUE screening. That's all I'm saying. — Robert Meyer Burnett (@BurnettRM) September 20, 2017

Justice League has a November 17, 2017 release directed by Zack Snyder, with the story by Chris Terrio and Zack Snyder, the screenplay by Chris Terrio and Joss Whedon, and stars 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 an Atlantean, Nuidis Vulko.

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.
