Snyder left the film in in early 2017 and was replaced with Joss Whedon, whose recut and reshot parts mixed with Snyder's work resulted in a jumbled mess of a movie. Snyder fans soon latched on seeing Snyder's vision and have been rallying for it ever since.
The cut has been described as an entirely new thing, with the original post-production team coming in to recut, rescore, and complete unfinished visual effects. It could possibly be a 4-hour film, or a 6-hour miniseries.
The release date hasn't been announced but will debut sometime in 2021. HBO Max, meanwhile, launches a week from today.
