After months of speculation and Zack Snyder slowly leaking details from "his" version of Justice League, DC storyboard artist Jay Oliva confirms that a Snyder Cut of the movie exists out there somewhere. Those close to the DC Extended Universe director had hinted he was further along with the movie than first expected, but now fans can take it as fact.

The superhero ensemble had a famously troubled production after Snyder departed late in the process due to personal reasons. Some were critical about the finished product after The Avengers director Joss Whedon boarded Justice League and overtook reshoots and post-production. Justice League became a movie that was criticized for two different styles and a guessing game of which director was responsible for which storylines.

Posting on Twitter after writer Mark Hughes denounced the existence of a Snyder Cut, Oliva told followers, "Zack isn’t the kind of director who creates the film in the edit bay. It’s all planned out meticulously from beginning to end. That’s how MoS and BvS was done." The debate continued until Oliva reiterated that fans "are responding to people saying that the Snydercut (prior to Whedon’s involvement) does not exist and is not a cohesive story because Zack left."

He concluded, "It may not be 100% polished but all of the planned scenes were shot and edited into a full timeline." Although Warner Bros. denies that Snyder had completed a rough draft of the movie before he left, Snyder's release of behind-the-scenes images on his personal social media led fans to believe that a Snyder Cut exists in some form.

Oliva says that 99% of Snyder's movie was done, meaning that it was likely only lacking VFX and other post-production effects. Several reshoots were filmed under Whedon, as well as the Russian family subplot that Snyder had no idea existed and the controversial CGI removal of Henry Cavill's mustache.

Explaining why Justice League linked heavily to 2016's Batman v Superman: Dawn of Justice, Snyder reportedly had a five-movie arc and intended to continue several plot threads with Justice League 2 and possible spinoffs. Ultimately, no one will really know how the DCEU would've continued if Snyder stayed with the franchise.

While Oliva didn't reveal what of the Snyder Cut he has seen or whether it could ever see the light of day, it is a massive coup for those who have championed for Snyder's vision of Justice League since the movie's lukewarm reception in theaters.
