Robert Downey Jr.'s mustache mistake in Avengers: Infinity War gets a lot of attention.

A mistake with Robert Downey Jr.'s mustache in Avengers: Infinity War by Marvel Studios was found again online and quickly went popular.

Marvel Studios recently admitted that they messed up one of Thor's more emotional lines in his conversation with Rocket Raccoon. 

This isn't the first time that Avengers: Infinity War has had problems.

A mistake about Robert Downey Jr.'s Iron Man has caused a Reddit post about a scene from Avengers: Infinity War to go viral online.

Downey Jr. makes the mistake when Iron Man meets Thanos for the first time by himself and tells the Mad Titan, "You throw another moon at me, and I'm gonna lose it!"

As soon as the camera zooms in on Downey's face behind the Iron Man mask, fans can see that his famous beard and goatee look very different from how they do in the rest of the movie.

The beard covers a lot more of his upper lip than it does in other shots, and the hair on his face isn't black like it is in the background of the MCU.

This mistake has been pointed out before, but since Infinity War came out in 2018, the most recent post on Reddit with over 5,000 likes and more than 100 comments from fans has helped it go popular online.
