Justice League will be the shortest DCEU movie to be released to date, with a runtime of 121 minutes -- a length that was reportedly ordered by the CEO of Warner Bros., Kevin Tsujihara.

The Wall Street Journal reports that Tsujihara made it clear that the first DC Films team movie's runtime was to be under two hours. In contrast, DCEU's prior efforts clocked in at 143 minutes (2013's Man of Steel), 151 minutes (2016's Batman v Superman: Dawn of Justice), 123 minutes (2016's Suicide Squad), and 141 minutes (2017's Wonder Woman).

The shorter runtime for Justice League is reportedly part of the tone shift for the DC Extended Universe. Geoff Johns and Jon Berg were brought in last year to bring in a lighter tone due to concerns that the Extended Universe was too dark and too violent. A rewriting of the Justice League script was the first thing the pair tackled, along with director Zack Snyder and screenwriter Chris Terrio. Snyder's first cut, delivered earlier this year, reportedly demonstrated progress to Warner Bros.' execs.
