The British star, known for portraying Superman in Zack Snyder's Man of Steel and Batman v Superman: Dawn of Justice, was recently rumoured to be in talks to join Tom Cruise in Mission: Impossible 6, and now MCQuarrie has made the news official with an entertaining series of posts on Instagram.

The filmmaker posted a photo of himself overlooking a river during a mountain hike, and wrote, "Say, @henrycavill. Had a thought. Curious if you're interested in a role in the 6th installment of Mission: Impossible. No pressure."

After one follower complimented MCQuarrie on his slick grey locks, Henry replied, "How can I say no to a man with such perfect hair....."

"@henrycavill excellent," the director responded. "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?"

The actor was game for the action-packed adventure, adding his own requirement: "Only if I get to fly for real," he posted, prompting MCQuarrie to state, "I do believe I specified practical stunts."

After Henry declared he's "in", MCQuarrie lifted a famous line from the spy franchise, quipping, "Outstanding. Welcome aboard. Your social media account will self destruct in 5 seconds".

Specific details about Cavill's role have yet to be released, but sources tell he will be a right-hand man to Cruise's unit boss in Mission: Impossible 6.

It is not yet known if Alec Baldwin, who took on the role of Cruise's superior in MCQuarrie's Mission: Impossible - Rogue Nation in 2015, will return, but franchise stars Rebecca Ferguson, Simon Pegg, and Jeremy Renner are expected to appear in the follow-up, which is set for release next year (18).
