2018's Mission: Impossible 6 just scored added DC's latest Superman, the actually-British-IRL Henry Cavill, to its roster. The casting news played out in inventive fashion on social media on Thursday night. It began with returning writer/director Christopher McQuarrie captioning an Instagram photo, "Say, @henrycavill. Had a thought. Curious if you're interested in a role in the 6th installment of Mission: Impossible. No pressure."

The deal, which will put Cavill onscreen with Tom Cruise and Rebecca Ferguson on July 27, 2018, was sealed in the comments section (text via Deadline):

Cavill: How can I say no to a man with such perfect hair…..
McQuarrie: excellent. Just a few caveats: must enjoy extreme heights, high speeds, motor vehicles of all varieties (especially aircraft), practical stunts, firearms, and sporadic exposition. All good?
Cavill: only if I get to fly for real.
McQuarrie: I do believe I specified practical stunts. You in?
Cavill: Oh ok…..I’m in!
McQuarrie: Outstanding. Welcome aboard. Your social media account will self destruct in 5 seconds.

McQuarrie will be the first two-time Mission: Impossible director, following 2015's Rogue Nation, which he also scripted. Before that, he directed Tom Cruise in Jack Reacher and penned the screenplay for another Cruise vehicle, Valkyrie.

Cavill, meanwhile, has a two-part Justice League movie on the way as well as his second standalone Superman movie.
