When Justice League begins, it doesn’t take long to realize something is off.

By now you probably know about the saga of Henry Cavill’s mustache, which threw an unwanted wrench into the movie’s production. Because of his commitment to the next Mission: Impossible, Cavill had to grow out a mustache, which then got in the way of reshoots for Justice League.

Instead of allowing Cavill to shave the mustache off, Paramount forced him to keep it, which put Warner Bros. in a rather unusual predicament—but it gets even weirder.

Warner Bros. apparently offered to digitally add a mustache to Cavill in the next Mission: Impossible movie, but Paramount refused. Warner Bros. even went so far as to show Paramount how easy it is to add a ‘stache, but still Paramount wouldn’t play ball.

In a Reddit AMA, a supposed VFX editor on Justice League explained the situation, calling Paramount petty for refusing to be flexible.

To me, as a fan, I was annoyed haha Paramount should’ve shaved him and stuck a fake one on for MI6. Ridiculously petty of them.

We did tests on already shot footage of Superman to add a beard as well to show the MI6 team at Paramount it was loads easier, and Warner Bros. offered to pay for all the beard adding shots in MI6. They said no.

So, Warner Bros. was forced to digitally remove Cavill’s mustache, which is most apparent in the early part of the movie. In other parts of the films, it isn’t noticeable at all. According to the editor, that first bit was done by a studio he wasn’t involved with, saying it shouldn’t have been approved because it looked so bad.

I guess the takeaway here is that if you had to choose between digitally adding or removing a mustache, always go with adding one.
