Cavill’s work on Fallout overlapped with when Justice League was undergoing reshoots, and the actor was contracted to keep the mustache intact.
But what was a problem for Justice League was a blessing to the internet, resulting in numerous memes being created.
Henry Cavill’s mustache could have just been a distinctive physical feature for August Walker in Mission: Impossible – Fallout and that would have been the end of this, but thanks to the controversy which is now called Mustachegate, it caused quite the stir online.
As a result, the Justice League VFX team had to digitally remove the mustache from those extra scenes in post-production, and the end results were… not great.
