Plot details remain under wraps with Cavill being rumored to portray a right-hand man to the head of Cruise's spy unit, Variety reported.
Director Christopher McQuarrie announced Cavill's involvement Thursday on Instagram writing, "Say, @henrycavill. Had a thought. Curious if you're interested in a role in the 6th installment of Mission: Impossible. No pressure."
The actor then responded to McQuarrie in the comments section writing, "How can I say no to a man with such perfect hair."
The exchange ended with the filmmaker referencing "Mission: Impossible" by replying, "Welcome aboard. Your social media account will self destruct in 5 seconds."
Cavill, best known for his role as Superman in Warner Bros. DC extended universe, will next be seen as the Man of Steel in "Justice League," due in theaters Nov. 17.
