I wonder if it's possible that the Justice League movie was edited in part (however minor) do to the fact that Cyborg is a black superhero?
Before the Black Panther made a billion plus, the overwelming thought was that black films do not play well in foreign avenues like China.
And today that may still be the case. The movie Shaft, which features all black leads, debuted poorly. But still might make up most of it's 30m budget because it has a high cinema score. But the shocking part about it is that when it hits international markets it will do so via Netflix on June 28. It's kind of surprising that Samuel L. Jackson's movie is going straight to streaming internationally in 2 weeks.
Zach Snyder just released another still of his JL cut and like many others before it features Cyborg. But this one seems to be directly inspired by a scene from Geoff Johns Darkseid War storyline when Cyborg hacked and went into the Green Lantern ring. Also in Cyborg # 7 by David Walker Cyborg's mother came back to life in a cybernetic 'ghost' form thanks to the motherbox. Zach's JL is heavily influenced by Geoff John's JL run so it's kind of strange for Geoff John to shoulder the blame for JL's failure. I believe that in part Geoff was force to cut out Cyborg's scenes so it would sell better in foreign markets like China.
