Justice League will feature 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, and Amy Adams will be back as Lois Lane.
Snyder recently talked with Yahoo about Justice League, comparing it to the 1954 film Seven Samurai that features seven masterless Samurai coming together to defend a village of farmers.
“I’m getting ready to start ‘Justice League’ on the 11th of April, so in like two weeks we start shooting,” Synder told Yahoo Movies. “It’s an intense, awesome, and gigantic undertaking because Bruce [Wayne] is having to go out and sort of ‘Seven Samurai’ the Justice League together, which is fun.
“It’s slightly monumental,” added Snyder, “and at the same time they’re starting to grapple with this coming threat.”
Regarding that "coming threat," it's assumed Darkseid may be the big villain, but not before members of the Justice League apparently battle it out with Aquaman.
Justice League has a November 17, 2017 release.
