Superman is ready to take on impossible missions.

Henry Cavill is joining Tom Cruise and the rest of the cast of "Mission: Impossible 6." Director Christopher McQuarrie confirmed the news on Instagram with a scenic photo of himself with the cheeky caption: "Say, @henrycavill. Had a thought. Curious if you're interested in a role in the 6th installment of Mission: Impossible. No pressure."

It seemed like wishful thinking, but then Cavill joined the conversation in the comments, replying "How can I say no to a man with such perfect hair....."

McQuarrie then joked, "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?"

After some back and forth, Cavill said he was "in," and the director wrote, "Outstanding. Welcome aboard. Your social media account will self destruct in 5 seconds."

Variety reports that Cavill will play the right-hand man of the head of Ethan Hunt's unit. Alec Baldwin played Ethan's boss in "Mission: Impossible - Rogue Nation," but it's unclear if he'll return in that role. The final cast line-up is not determined, though Rebecca Ferguson, Simon Pegg, and Jeremy Renner are expected to return.

"Mission: Impossible 6" is set to open in theaters July 27, 2018.
