If you're a Zack Snyder fan worrying that Joss Whedon is currently undoing everything your favourite film-maker had already done on Justice League before he left the project, you probably don't need to worry too much.
According to star JK Simmons - who, of course, plays the newest version of Jim Gordon in the ensemble - Joss Whedon is committed to telling the story that Snyder was before he stepped out of the director's chair. He might be in charge of reshoots and additional material, but Whedon won't be messing too much with the blueprint his predecessor mapped out.
Simmons spoke to Red Carpet News TV, and said that while Whedon is definitely important to Justice League, he hasn't changed what Snyder was doing in terms of the story:
“I wasn’t involved with Joss at all, (he was here for) some of the reshoots and I wasn’t involved in that. But I think he’s really dedicated to finishing the story that Zack was telling. Again, that’s my understanding from my vantage point.”
It's a statement echoed by some of his co-stars in this month's Justice League-focused issue of Empire magazine (via Comic Book Movie), in which Gal Gadot firmly stated whose film it is:
“This is Zack Snyder’s movie. Joss only did a few weeks of reshoots. He was Zack’s guy and knew exactly what he wanted to get… He has a beautiful vision.”
Ben Affleck spoke similarly:
“I didn’t sense that we were moving towards something that felt like The Avengers. Joss is more than just an Avengers director. He’s a good storyteller, full stop. In mid-stream, Joss got on and part of what interested him was the puzzle aspect of it, fitting in pieces that weren’t there yet. He put the rest of the pieces in and gave it his own imprimatur. Joss came in and walked a very fine line between Zack’s sensibility, tone, and direction. We found a really fun and inspiring synthesis of their two forms of storytelling. I was so glad everyone showed up to work for Zack.”
And Ezra Miller talked about how Snyder's vision for the characters continued through the completed film under Whedon's guidance:
“It’s a heroic act at its route. He called each and every one of us and took the time to explain something that defies, in many ways, explanation. He told us exactly how it was going to go down, which was true to course. He fascinates and amazes and staggers me. Zack Snyder, ultimate [frick]ing legend. Forever.”
So maybe don't go expecting something not Snyder-like, in short.
