Earth under attack in final Justice League trailer

What look like alien invaders attack Earth in the latest and final Justice League trailer, putting the likes of Wonder Woman, Batman, the Flash and Aquaman in charge of saving humanity.

The video has just debuted at New York Comic Con and starts with Lois Lane dreaming about Clark Kent - aka Superman - who apparently died in the last film, Batman v Superman: Dawn of Justice.

Violence, war and terrorism is on the rise, TV news announcers grimly tell Lane as she wakes form her dream, but something even darker is on the horizon.

"Divided, we are not enough," Bruce Wayne tells the other heroes, "the world needs Superman, and I made him a promise, which is why I've brought you together."

More of the battles teased in earlier trailers are shown, including Aquaman yelling "yeah" with a hillbilly accent while riding the Batmobile.

As the first trailer released since Joss Whedon took over from Zack Snyder as director on the film, some online observations have noted it's brighter, clearer footage with a lighter tone to earlier teases.

Justice League will be released in November.
