Fans of "Justice League" are proving to be as vigilant as their fictional heroes, as several cosplayers have gathered in a picket against Warner Bros., the production studio of for the said movie, to demand that they release Zack Snyder's original cut.

After the disappointing opening week of "Justice League" back in November last year, Warner Bros. is now being urged by more than a dozen hardcore DC fans right at the main office of the studio in Burbank, California for Snyder's cut of the film. Snyder was initially the director of "Justice League," and he actually oversaw most of the film until "Avengers" director Joss Whedon had to step in for him due to his family problems.

Apparently, Whedon modified the some of the movie scenes which Snyder had already shot, leading some of the fans to make the assumption that Snyder could have done better. Fans also blame Snyder's departure for the film doing poorly in the box office, only grossing as much as $675 million worldwide compared to the last two movies of DC, "Wonder Woman" ($821 million worldwide) and "Batman V Superman: Dawn of Justice" ($873.6 million).

It also seems that it was not only the fans who have been wanting the release of Snyder's cut, but also his fellow filmmakers. Most notable is "Justice League's" cinematographer Fabian Wagner, who stated that Whedon's version was shorter than he expected and hoped to see a director's cut.

He added, "What I love about his [Snyder's] director's cuts is they are long, but he takes his time to tell the story. I've never watched any of his directors cut and thought 'This is long.' Whether they are three hours long, or three hours and ten minutes, they always seemed to go quick."

Despite only a few people showing up in a physical protest at Warner Bros. studio at California, the online call-to-action from DC fans has now gained a significant momentum. There is a widespread use of the social media hashtag #ReleaseTheSnyderCut, along with a petition on Change.org, which has now gained 167,000 at the time of writing.

It remains to be seen whether Warner Bros. will give in to the fanbase clamour as they have yet to comment on the issue.
