This story gets funnier and funnier the more we hear about it. We reported a while back that, during the extensive Justice League reshoots, Henry Cavill a.k.a. Superman presented a particular challenge. This was thanks to the moustache he had grown to play his character in the upcoming Mission: Impossible 6, on which production was already underway.
Warners eventually had to digitally remove Cavill’s facial hair in post-production, after Paramount Pictures refused to let him shave it off. Now, it turns out that Warners actually had a counteroffer for Paramount: let Cavill shave and they would digitally grow Cavill’s moustache for MI: 6.
On a Reddit thread discussion, a VFX artist who claimed to have worked on Justice League (see our review) claimed that this would have been a much simpler solution than the far more complex process of digitally removing the moustache.
