There are a lot of fans that want the Snyder Cut for the Justice League, so I figured, it may be beneficial to have a thread compile all known differences between the two (apparently three because Zack Snyder had enough footage for two films) takes for the Justice League as well as what would be included for the Snyder Cut.
-It has been stated that Joss Whedon changed the dialogue between Deathstroke and Lex Luthor
- Zack Snyder did not make the scenes where:
•Wonder Woman wore the “ceremonial robe”
•Batman says “Something’s bleeding”
•Superman is interviewed by the kids nor Batman interacting with the Parademon
•Flash describes his annoyance with brunch
•Aquaman tries to excessively flirt with Mera as well as him being caught on Wonder Woman’s lasso
-Zack Snyder had the original movie follow:
•opening with Bruce Wayne looking for Aquaman
•having Batman try to commit suicide (towards the end of the film with the Batmobile)
•rumored to potentially have Batman die
•Darkseid appears and, I believe, kills Steppenwolf
•Vulko and Iris are in it
•The movie ends with a nice segue to Aquaman
•More background on Victor Stone and Barry Allen
•A scrapped scene where the Green Lanterns meet
I know I am forgetting some, but I hope it was a good idea to include this.
As for what Zack Snyder will do in the future, it has been said that he may make a Webcomic of his cut. Also, there is a news page stating that he helped with the Aquaman film, which was not what Warner Bros. wanted, so hopefully, he will be reinstated as a contributing member for future movies.
