If the humans of the DC Films Universe thought the Kryptonians were bad, they have another thing coming to them. According to director Zack Snyder, he will draw heavily from comics legend Jack Kirby's work for "Justice League," which means Mother Boxes, Apokolips, the New Gods and more.

"[Jack] Kirby's crazy in a great way, and there's a lot of influence, you know, the New Gods stuff, we were digging on that -- and that's the Mother Boxes and that sort of Apokoliptian world and all that. I don't know if I can call it 'weird,' he said with a laugh.

"The kinda scope-y, sci-fi, cool, what I think is fun stuff," he continued. "I think inherently when you start to talk about a bad guy that would justify the Justice League, you have to have a good threat that's fun and kinda crazy. And the Mother Boxes are always fun, DC-weird tech, you know?"

Snyder included Mother Box technology in "Batman v Superman: Dawn of Justice," though the scene was cut from the theatrical version of the film; it will be included on the Ultimate Cut Blu-ray and DVD and is available to watch online. The scene also offered a glimpse of Steppenwolf, who will be the main villain of "Justice League."

Opening Nov. 17, 2017, "Justice League" stars Ben Affleck, Henry Cavill, Gal Gadot, Ezra Miller, Jason Momoa, Ray Fisher, Amy Adams, Jesse Eisenberg, Amber Heard, Jeremy Irons and J. K. Simmons.
