It seems Justice League also digitally altered Henry Cavill's hands, in addition to his mustache. The movie's CGI snafu has hung over Warner Bros. and Cavill's heads for months now. While the latter has even gotten in on the fun by this stage (see his hilarious shaving video), it remains a popular topic of conversation among fans. Now, it appears that Cavill's face wasn't the only part of the actor that was digitally altered in the film.
The issue arose during Justice League's now infamously extensive reshoots. Cavill was in the middle of filming Mission: Impossible - Fallout (where his character rocks a Tom Selleck-style 'stache) when he returned to re-film his scenes as Superman for the movie. Paramount refused to allow him to shave his facial hair, even after WB offered to pay to digitally add Cavill's mustache just so the actor could shave it off while reshooting his scenes in Justice League. As a result, Cavill's facial hair had to be digitally removed in Justice League instead, and the end result simply didn't look right (despite costing millions of dollars).
It's a shame the film's poor CGI continues to haunt Justice League - a movie that was supposed to solidify WB and DC Films' plans to build an interconnected film universe. That said, it seems both companies are ready to move on the kerfuffle, now that DC Films has undergone extensive management reorganization.
