A tough, new gang of superheroes has assembled.

After tantalizing fans with "Justice League" teasers and posters last week, Warner Bros. finally dropped the movie's first official trailer on Saturday. Like the superhero flick itself, the preview is packed with mighty DC Comics heroes. We get to see Batman (Ben Affleck) and Wonder Woman (Gal Gadot) as they work to put together a team of heroes to take on a scary threat.

The trailer doesn't spend much time focusing on the danger ahead. While we're told that an attack is coming, the main focus is the hero gang. Aquaman (Jason Momoa), Cyborg (Ray Fisher), and the Flash (Ezra Miller) all get a chance to show off their superhuman abilities, and from what we can see, the team should be an unstoppable force.Of course, conflict and clashes are inevitable. The metahumans are set to face off against some scary foes, as we'll see when "Justice League" opens in November.
