Now that Zack Snyder's Justice League is out and about on HBO Max, it's hard to even think about the original 2017 cut. Nevertheless, there was a time without the once-elusive Snyder Cut, a time when Snyder was desperately trying to get the film released.
Snyder's promotional campaign to get the Snyder Cut released is closely aligned with the filming dates for Army of the Dead. With this in mind, it's not hard to imagine that there's some overlap between the two projects.
Army of the Dead references the Snyder Cut
In the new Zack Snyder movie, one scene appears to have a subtle reference to the Snyder Cut. Obviously, the following explanation will have heavy spoilers for the recently released Netflix movie. So, proceed at your own risk.
In the final act of the film, the characters successfully open the movie’s mysterious vault. The vault is stacked with millions of dollars, but most importantly there's a reference to Zack Snyder's Justice League. Of course, this shot is over pretty quickly, so you'll have to pay attention.
Amidst the money, the corner of the vault has a mysterious rack of film reels in their protective cases. Before the release of the Snyder Cut, Zack Snyder teased the film's existence with pictures of the movie’s film reels. The film canisters even feature the exact same red labels. Knowing Snyder, these are the probably the actual film reels for Zack Snyder's Justice League.
Other similarities between the two movies
Zack Snyder doesn't reference his version of Justice League much throughout the movie. However, Army of the Dead does use the same camera lens as multiple scenes in Justice League.
Army of the Dead was predominantly filmed by Snyder using Canon 50mm f/.0.95 fullframe lenses he bought on eBay. These lenses result in a very dreamlike look that was used for Justice League's 2020 reshoots. It's a small connection, but one that marks an important turn in the director’s filmmaking journey.
