Ciarán Hinds, best known for 
Munich, 
Road to Perdition and more recently, 
Game of Thrones, spoke to 
The Independent and confirmed his casting as 
Steppenwolf in Zack Snyder's
 Justice League. It seems this version of 
Darkseid's uncle and military general will be completely CGI. "
Basically they’re going to construct something, digitally, and then they will use my eyes and mouth,"said Hinds on his role as the film's primary antagonist. He added, "
He’s old, tired, still trying to get out of his own enslavement to Darkseid, [but] he has to keep on this line to try and take over worlds."
Previous rumors state that Steppenwolf invades Earth to retrieve three Motherboxes left on the planet after a battle with the Amazons, Atlanteans and mankind that occurred 30,000 years ago.
The use of a motion-captured, fully-CG villain continues a trend that began with 
Batman v Superman's Doomsday and will continue with 
Wonder Woman's Ares.
ABOUT JUSTICE LEAGUE:
	SYNOPSIS:  Fueled by his restored faith in humanity and inspired by Superman's (Henry Cavill) selfless act, Bruce Wayne (Ben Affleck) enlists newfound ally Diana Prince to face an even greater threat. Together, Batman and Wonder Woman work quickly to recruit a team to stand against this newly awakened enemy. Despite the formation of an unprecedented league of heroes -- Batman, Wonder Woman, Aquaman, Cyborg and the Flash -- it may be too late to save the planet from an assault of catastrophic proportions.
