10 Behind The Scenes Reasons For DCEU Characters' Quirks

Even the most casual-minded of moviegoers who aren't Chronically Online likely realised that something was a little... off with Superman's face in the Joss Whedon version of Justice League.

From that opening scene in which we glimpse the Man of Steel's mug as captured by a boy's phone, even those with no awareness of the movie's behind-the-scenes troubles surely knew, perhaps just semi-consciously, that all was not right.

And indeed, this feeling pervades throughout the rest of the movie, with Superman having a strangely robotic-looking jaw, as though Henry Cavill had just recently had delicate dental surgery and needed to hold his face in a very specific way.

But the real reason for this? The aforementioned two months of reshoots intended to "fix" the film's perceived problems, requiring all major cast members to return to set.

Except, in Cavill's case, he was already busy shooting his role in Mission: Impossible - Fallout, which required him to have a bushy mustache.

And so, when Paramount executives rejected the idea of shaving Cavill and filling in his mustache for Fallout with VFX, Joss Whedon was forced to film Cavill with a mustache and digitally remove it in post-production.

The end result speaks so offputtingly for itself, that Warner Bros. executives refused to delay the film in order to ensure they were paid hefty bonuses, while Cavill's Superman was left with a distractingly dodgy-looking CGI lower-jaw.

Thankfully Zack Snyder's Justice League restored the original sans-mustache footage, and the 2017 movie largely exists now as little more than a fading - if traumatic - memory.
