The trailer for Mission: Impossible – Fallout has been out for months, and somehow we all missed its most compelling component. We speak, of course, of Henry Cavill's reappearing beard.

Henry Cavill's beard is already a contentious pop culture topic, although that's more on whoever removed his facial hair in Justice League than him. This time, an optical illusion or possibly a mistake in post-production seems to be at work — one that makes Henry Cavill generate a beard where, previously, there was none.

Please watch the GIF in the below tweet, which Michael Chu graciously shared on Monday. Warning: it's weird as hell!

Hi I shared this gif with some friends of mine for thirst reasons and then one of them pointed out that Henry Cavill appears to spontaneously grow a beard and WHAT THE FUCK pic.twitter.com/gIyPLvSWfh — Michael "Abolish ICE and punch Nazis" Chu (@MichaelChu7) June 25, 2018

Friends, oh my god. What? WHY DOES HE NOT HAVE A BEARD AND THEN JUST... HAVE ONE? Why? How? When? Where? Who?

Upon further viewings of the full trailer, the Great Beard Mystery is possibly just the result of a weird lighting moment. It's more fun to believe, though, that Cavill generated his beard through the sheer force of his air punches.

So we will believe that.
