The real mission fans have chosen to accept is to obsess over Henry Cavill's arm reloading scene in "Mission: Impossible - Fallout."

The arm cock move has become a meme, but it's also being analyzed for possible continuity errors. Is it just a trick of the light or does he 1) grow a beard and 2) grow a shirt pocket within seconds?

Reporter Jake Hamilton shared a clip of his talk with "M:I-6" stars Henry Cavill and Simon Pegg, asking them both about Henry's beard growth mystery:

Reporter: "There is a GIF floating around of you, and it's the arm cock. But not just that. It looks like in that moment you grow a beard. Have you heard about that?"

Henry Cavill: "Yeah, yeah. Yes. I've seen it as well."

Reporter: "Is there a story behind that? Or is it just the lighting, you happen to hit the light the right way?"

Henry Cavill: "It's because I punch so hard when reloading my fists that I actually grew a beard in that moment. I made facial hair history."

Simon Pegg: "There's so, so much testosterone at work there. That's how he gets up every morning, clean shaven. He goes [does arm cock movement]. And then he's got a beard."

Nice. Henry Cavill also made "facial hair history" with MustacheGate, the CGI-erased mustache for his Superman in "Justice League." That was also due to the magic power of his "Mission: Impossible" beard. Bow to its impact.

"Mission: Impossible - Fallout" had the best box office debut of the franchise to date, and we're expecting it to continue to do well this weekend. Check out all of Moviefone's interviews with the cast and director Christopher McQuarrie.
