Rumors suggest that Joss Whedon’s contributions to the script for Justice League was apparently under two dozen pages and consisted of adding the scenes that Zack Snyder requested to be added to the mix, as well as excising some extraneous material from the film’s narrative.
Forbes contributor Mark Hughes recently discussed Joss Whedon’s additions to the Justice League script on the Superhero News podcast. On the podcast, Hughes took note that the total amount of content that was added or rewritten consists of slightly less than two dozen pages:
“I think that there’s some confusion… About what, precisely, he has to do. The idea that [him getting a credit relates to revising at least a third of the movie’s screenplay] – that’s not how it works. There are a lot of ways you can contribute to changing a script… What I heard was [that Whedon did] roughly two dozen pages of additional material and rewrites, and on top of that… There’s some stuff that’s been cut, and scenes that have been cut, and characters who have been cut out of the film – things have been changed and things have been cut. So when you look at the totality of his involvement and his work and his impact on that script, yes, it’s fair to say probably a third of the script total when you add [the scenes that he added, deleted, and/or replaced while directing additional photography] – it probably amounts to enough that yes, he would qualify for [a writing credit].”
For frame of reference, the typical screenplay for a movie of about two hours in length is 110 to 120 pages, with one page roughly translating to a minute of footage – so about two dozen pages of screenplay ought to translate to twenty to thirty minutes of film. Knowing that Zack Snyder usually likes exploring his settings in-depth (a practice that usually translates to a running time closer to two and a half hours, or longer in the case of the extended cuts he did for Watchmen and Batman v. Superman: Dawn of Justice), a movie like Justice League might be longer than two hours, and this would mean that Whedon’s changes only account for about a sixth to a fourth of the movie’s story.
Hughes suggested that these changes are placed throughout the script as opposed to revising just a single section of the film, meaning that dialogue and story elements have been reworked. However, he also suggested that these changes are not meant to remake the entire movie so much as they are to create a more whole film with a consistent narrative. In general, this story lines up with producer Charles Roven’s report that Whedon’s work will be in-line with Snyder’s original vision, even if it does suggest Whedon did more work than initially reported (most likely due to the fact that scheduling the film’s additional photography was a bit of a headache for Warner Brothers).
