“Justice League,” the Zack Synder-directed DC Extended Universe film set to debut in theaters this November, will focus on the newly formed Justice League’s attempt to stave off an alien invasion in the absence of Superman, who died at the end of “Batman v Superman: Dawn of Justice.” The invasion will be led by none other than Steppenwolf, an otherworldly New God who will be played by "Game of Thrones" star Ciaran Hinds. While the 64-year-old actor seems like a strange choice to play an unfathomably powerful conqueror of worlds, it turns out that the film’s version of Steppenwolf will largely be a computer-generated character.

“Basically they’re going to construct something, digitally, and then they will use my eyes and mouth,” said Hinds revealed in an interview with Independent.

Hinds’ career stretches as far back as 1980, but the actor has never played role that required motion-capture. To prepare for the experience, he enlisted the help of actor and friend Liam Neeson, who recently came off a similar role as a giant talking tree in “A Monster Calls.” Hinds said Neeson sent him several pamphlets about motion capture acting.

Hinds also dropped some extra information about his character, about which there has been precious little revealed. “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 [to] and take over worlds,” he shared.

Created by Jack Kirby, Steppenwolf first debuted in “New Gods” #7 in 1972. One of Darkseid’s Elite, Steppenwolf is inhumanly strong and nigh invincible. He once led an army of parademons against the forces of Earth, only to be repelled by the Justice League at a great cost to Earth’s heroes. Steppenwolf is also one of the few characters in the DC Comics universe to survive an encounter with Doomsday, the creature who -- in “Batman v Superman” -- was adapted as the reanimated, mutated corpse of General Zod.

Debuting in theaters November 17, “Justice League” is a production of Warner Bros. Pictures directed by Zack Snyder and starring Ben Affleck, Henry Cavill, Gal Gadot, Jason Momoa, Ezra Miller, Ray Fisher, Amy Adams, Willem Dafoe, Jesse Eisenberg, Jeremy Irons, Diane Lane, Connie Nielsen and J. K. Simmons.
