Something people really don’t like about the theatrical release of Justice League, or “Josstice League” as they mock it as, is the amount of humor in the movie compared to Batman V Superman: Dawn of Justice. While it’s true some of that can be blamed on Whedon (like Flash laying on Diana), it appears some of the stuff people complain a lot about was there before Joss took over.
Back when Zack Snyder was still filming the movie Warner Brothers hosted media (the evil “bloggers” some people demonize on social media) on the set to actually hang out, watch scenes being filmed, and interview Zack about the movie. These interviews would normally be released right before the release, but due to the drama surrounding the production and what happened with Zack that didn’t happen. But the set visits still happened, and those people are now talking about what they saw there.
According to Eric Vespe, formerly of Ain’t It Cool News, a lot of the tone and humor people complain about is from Zack and not Joss:
I’m actually pretty curious to see this new all-Snyder version of Justice League. Hardcore fans should be warned, though, a lot of the humor they revolted against was from his version. I was on set and he told us he was leaning away from the dourness of BvS even then.— Eric Vespe (@EricVespe) May 21, 2020
Snyder also showed us a rough cut of the entire scene where Bruce Wayne shows up at the Flash’s place and it is almost exactly the same in the theatrically released cut, one-liners and all.— Eric Vespe (@EricVespe) May 21, 2020
The scene we saw them shooting was the League answering the bat signal call from Gordon and that ended with the Flash doing his fumbling nerdy meta jokes, too, which also made it into the theatrically released film. Not saying it’s a good or bad thing, just fair warning.— Eric Vespe (@EricVespe) May 21, 2020
So next year when the movie (or mini-series) streams on HBO Max and those light-hearted scenes remain, it’s not them using stuff that Whedon shot. That’s probably going to be a complaint and accusation when it happens, but according to the people who were on the set and watching those scenes being filmed; they were done intentionally by Snyder.
