UPDATE: Since the publication of the original article, Richard Cetrone reached out to CinemaBlend and denied claiming there's a Justice League cut sitting around from Zach Snyder. So, at this point, we have no idea what's going on. It seems reasonable to think it's possible such a cut does exist, but there is absolutely no confirmation at all. So, take the original article for what it's worth.
Although Justice League didn't receive quite the critical lashing as Batman v Superman: Dawn of Justice and Suicide Squad did, it still underperformed critically and was a box office bomb. Since it dropped in theaters last November, there have been calls for Warner Bros to release the "Zack Snyder cut" of Justice League, i.e. the version of the movie that better reflects the director's original vision before he departed the production rather than the Frankenstein-like assembly the masses watched. Now according to Richard Cetrone, a stunt double who worked on the movie, there is a Zack Snyder cut that is sitting around somewhere.
According to a screenshot posted by DC Films Universe, Richard Cetrone (who was Ben Affleck's stunt double on Batman v Superman: Dawn of Justice and Justice League, as well as David Thewlis' stunt double on Wonder Woman) not only does he believe that a Zack Snyder cut of Justice League exists, but with enough support from fans, perhaps Warner Bros might be willing to release it. The latter certainly won't be a problem, as many DCEU fans have expressed enthusiasm for seeing such a version of the movie, with a petition for the Zack Snyder cut being posted online only days after Justice League was released. A small group of fans even stood outside the Warner Bros lot in Burbank, California this past weekend to show their support for this endeavor.
It's worth noting that this new information conflicts with a previous claim that the Zack Snyder cut of Justice League doesn't exist. In case you need a refresher, it was announced in May 2017 that Snyder stepped away from the movie due to the tragic death of his daughter, and Joss Whedon, who'd already been brought on to re-write certain scenes, was tapped to helm the reshoots and the rest of post-production. Because of that, a VFX artist who worked on Justice League said that because Snyder hadn't worked on the DC superhero team-up story for more than half a year, there was no way to assemble a Zack Snyder cut together.
Either way, we shouldn't discount Warner Bros releasing an extended version of Justice League for Blu-ray, DVD, Digital HD, etc, even if it's not this specific Zack Snyder cut. Both Batman v Superman: Dawn of Justice and Suicide Squad received such treatments in 2016, and according to one rumor, an extended version of the Justice League theatrical cut will be released to the public, rather than one that shifts the story closer to what was envisioned when Zack Snyder was overseeing things.
Justice League has largely wrapped up its theatrical run, and while a home media release date hasn't been officially announced yet, I suspect it will arrive within the next month or two, so stay tuned to any updates about an extended cut, Zack Snyder-inspired or otherwise. The next DCEU installment, Aquaman, dives into theaters on December 21.
