The actual story behind why Zack Snyder left the Justice League in 2017
Even as someone who has followed every step of the Snyder Cut journey, I was surprised to hear Zack Snyder admit he was struggling with the studio and fighting for his version of the Justice League when Autumn died. And that Snyder imagined for a moment a world in which he would continue to fight, because as he says, these creative arguments between executives and storytellers take place in every film. But the incessant battles for the Justice League, and probably for Snyder’s overall vision for the DCEU, had completely robbed Snyder of his ability to scrap further. He said he had “no energy” for it. They wore him down and all he could do was walk away.
