This fan edit uses the Snyder Cut as the foundational source but transitions over the course of the edit into the Whedon third act.

The Snyder Cut and the Theatrical Cut, mixed and blended to create a theatrically viable version of Justice League.

Shortened to 133 minutes, focused on action and main plotline, with most of the character backstories removed or significantly shortened, this version relates heavily to 70s aesthetics but is not limited to it. The movie got used, damaged look and most of the music was replaced with some 70s (but not only) funk, rock, and cues taken from another movie soundtracks and some TV series themes.

Remixed version of Zack Snyder's Justice League is 47 minutes shorter, restructured and reframed to 2.31:1 with some theatrical additions and new opening credits sequence based on "Motherbox clip". Some scenes has been rearranged - for example: Bruce Wayne starts searching for Aquaman after the "history lesson" and we meet Flash earlier. Most of the sequel baits present in official version are gone, also removed are many scenes which were not necessary to keep the plot going. Movie ends just like theatrical cut without extended epilogue.

The Justice League: Ultimate Edition, aims to reinsert as much deleted footage from trailers, TV spots, promo material, behind the scenes featurettes, VFX Reels, Blu-Ray deleted scenes and a few fanedits to create the longest possible version of the Theatrical Cut.
It's not anything too spectacularly different, but it's four minutes longer with almost 70 alternate, deleted, extended and new shots and scenes added to the running time. Everything has been painstakingly colour matched with the theatrical footage and rescored with the OST with added SFX where needed to fill gaps.
This isn't any fancy Snyder Cut, but more of the movie you saw in cinemas with a few extra moments sprinkled throughout.

A more streamlined Justice League cut with added deleted scenes from trailers and bonus material. I’ve tried to keep it in the spirit of the previous films as much as possible, while still keeping the lighter tone. This is to improve the balance between the Joss Whedon reshoots and what Zack Snyder originally shot.
