Superman star Henry Cavill has been unveiled as a cast member in the forthcoming sixth instalment of the Mission: Impossible movie franchise, with his participation being announced in a particularly unique.

It took the form of Cavill ‘accepting’ a role as a top-secret mission via an Instagram conversation with the new film’s director, Christopher McQuarrie.

“Say, @henrycavill. Had a thought. Curious if you're interested in a role in the 6th instalment of Mission: Impossible. No pressure,” the 48 year old director, who directed 2015’s fifth film Rogue Nation, wrote on Instagram.

Cavill promptly replied: “How can I say no to a man with such perfect hair,” to which the director wrote: “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?”

“Only if I get to fly for real,” Cavill wrote, referring to his role as Superman that he’s held down since 2013, McQuarrie responding: “I do believe I specified practical stunts. You in?”

The Justice League actor confirmed: “Oh ok….. I'm in!” with McQuarrie concluding the correspondence with: “Outstanding. Welcome aboard. Your social media account will self-destruct in five seconds.”

The amusing exchange took place on Thursday night (March 16th), following which the movie industry trade publications like Deadline have confirmed that Cavill, 33, will indeed be taking part in the new Mission: Impossible.

Rogue Nation got a great reception when it came out, with the recurring star Tom Cruise featuring alongside Ving Rhames, Simon Pegg, Jeremy Renner, and Rebecca Ferguson. As of the time of writing, only Rhames has said that he won’t be involved with the sixth film.
