Justice League (movie)
Ciarán Hinds as Steppenwolf: A general of the alien race, the New Gods, from the planet Apokolips who is charged with hunting down the three Mother Boxes on Earth for his nephew and commanding officer Darkseid. The character had previously appeared in the extended Ultimate Edition of Batman v Superman: Dawn of Justice, in which he communicates with Lex Luthor through Kryptonian hologram technology. In March 2017, Ciarán stated that Steppenwolf is old, tired and trying to get out of his enslaved position under Darkseid. Hinds will portray the villain through use of motion capture performance and received help in that process from his friend Liam Neeson, who had recently done similar work in A Monster Calls.
