In 2019, fans of the film called on Warner, the producer of the Justice League, to "release an edited version of the guide" through social media, buying newspaper pages, and organizing crowdfunding. The "Batman" in the film Affleck, "Wonder Woman" Gal Gadot, and "Sea King" Jason Momoa also expressed their support for this action. At the end of 2019, Warner executives expressed their support for Zach Schneider's comeback to produce the director's cut version of "Justice League".
In May 2020, Zach Schneider announced that most of the original team of the film was called for post-production, including soundtrack, editing, visual effects, etc., and some actors were also recalled to record the dialogue. On the 20th of the same month, HBO Max announced to give Zach Snyder a budget of 20-30 million US dollars to complete the film according to his own wishes, and officially confirmed the production of the director's cut version of "Justice League"; in September of the same year, HBO Max added 70 million U.S. dollar budget, including the cost of re-shooting and post-production; in October, it was announced that Ben Affleck, Ray Fisher, Amber Heard, etc., were all involved in re-shooting; on the 22nd of the same month, it was announced that they had starred Jared Leto of "Suicide Squad" will return to play the role of the clown in the film; on the 24th, it was announced that Joe Manganello would participate in the make-up work; on the 28th, it was announced that the film would start making-up; on November 18, the director Zach Schneider said in the live broadcast of the trailer that the film has about 2 hours of footage that is different from the theater version. Part of the two-hour footage shows the relationship between Superman and Batman.
In addition to the plot and characters, the Zhadao version and the theater version have different photography. The theater version probably only uses 10% of the main body shot by the photographer Fabian Wagner. The soundtrack used in the theater version was re-arranged by the master Danny Elfman, who was later invited by Warner; and the lead version will use the original soundtrack created by the original composer Junkie XL.
