There may be no more famous mustache in the world that the one that Henry Cavill wore in Justice League that nobody saw. It was a major topic of conversation leading up to the release of the DC universe blockbuster, but up until now, all we had to actually see was Cavill's facial hair in Mission: Impossible - Fallout and the rough CGI from Justice League. Now, however, we have an actual picture of Superman with a mustache, and it's everything you ever dreamed of. Check it out.
While it wasn't necessarily difficult to guess what Henry Cavill looked like wearing both a mustache and a Superman costume, actually seeing it is another matter entirely. It's sort of amazing. Many responding to the image posted on the Pop Culture Pod Twitter page think the mustache actually looks pretty great and that Cavill should have been allowed to keep it in the film. Perhaps a Superman with complete facial hair, a beard as well as a mustache, could have worked. Maybe, given the situation, it would have been the best option.
If you're unfamiliar with the epic story of the Cavill-stache, It all came about following the conclusion of principal photography on Justice League. Henry Cavill went off from that movie and began to shoot Mission: Impossible - Fallout, a role in which he had a full beard and mustache. Then Zack Snyder stepped down from directing Justice League for personal reasons, or was fired, depending on which story you believe. Joss Whedon was brought into finish the film, and much more extensive reshoots than what had been originally planned were scheduled.
Unfortunately, Cavill was still in the middle of shooting Fallout when these new reshoots took place, and Cavill couldn't shave, as doing so would have delayed production of the Mission: Impossible movie. The decision, the only one available really, was to shoot Superman with a mustache, and then remove it from the picture via the use of digital effects.
The end result was...rough to say the least. The longer than usual reshoot schedule meant that post-production had less time than usual to do the work of eliminating the facial hair. It's pretty obvious when the CGI Cavill is on the screen, which is mostly disappointing because it takes you out of the experience during what is otherwise one of the biggest moments in the film.
The future of Superman in the DC universe is unclear. There are apparently no plans to make another Superman movie at the moment, so when or if we might see Henry Cavill again in the Superman costume, sans-stache is anybody's guess. Though it seems reports that Cavill was officially done with the role may have been premature.
Whatever happens, at least now we know what all the fuss was about.
