Marvel fans have spotted a continuity error in Avengers: Infinity War – and it involves Tony Stark's mustache.
As pointed out by a Reddit user, Iron Man's facial hair seemingly changes while he's facing off against Thanos towards the climax of the movie. In two stills posted side by side, his facial hair looks much thicker and his mustache is a slightly different shape in one image than in the other. Of course, this is likely to be the result of reshoots, but fans found the mistake pretty funny all the same.
