When Justice League was released in Iceland, where films in non-Icelandic languages are subtitled rather than dubbed, Jason Momoa's single line in Icelandic was so unintelligible that it had to be subtitled in Icelandic (usually prompting laughter from audiences).

Director Zack Snyder and his wife, producer Deborah Snyder, stepped back from finishing the film after their daughter's suicide in March 2017. They tried appearing in the film as a way to cope, but two months later decided to leave the project to spend time with their family. Joss Whedon, who had signed on to Batgirl, took over directing and shot additional scenes that had to be included in the final cut. Warner Bros. stated that Whedon would direct and write in the same style as Snyder, so there would be no tonal shift or noticeable changes in style. However, Whedon controversially fired Snyder's composer Tom Holkenborg and replaced him with Danny Elfman, who had previously scored Whedon's Avengers: Age of Ultron (2015). Nevertheless, in 2021 Snyder succeeded in showing the film as he had originally intended.

Extensive reshoots in London and Los Angeles in mid-2017 added roughly $25 million to the film's budget. Henry Cavill worked on the reshoots and Mission: Impossible - Fallout (2018) at the same time. His role in the latter project required him to grow a mustache, but Paramount would not allow the actor to shave it to play Superman in the reshoots. This meant Cavill's mustache had to be digitally removed in post-production. Due to the tight schedule, however, the results were crude and were among the many criticisms of the film's theatrical version.

Holt McCallany, who plays the thief in the first scene with Batman, said the scene was written and shot by Joss Whedon for comedic purposes, but that Warner Bros. preferred to open the film with a more serious tone and the scene was re-edited. When McCallany returned to his home in New York, he found a bottle of his favorite champagne at his door and a note from Whedon reading, 'To lost battles. Gratefully, Joss.' McCallany appreciated Whedon's gesture and had the letter framed.

(At about 1 hour 50 minutes) At the end of the film, Superman and Flash race to decide who is faster. This is a direct reference to the many races in the comics, such as Superman No. 199 and others, in which the two occasionally race to determine who is the fastest man alive. In the comics, Superman limits himself to running instead of flying, a much more exhausting form of movement for him, which allowed the far more experienced Flash (in this case the Wally West version) to win at least once. In a much later story, however, the Flash (Barry Allen) is said to have raced Superman for an emergency, noted that these races were for charity, and when he started running seriously he instantly pulled far ahead.
