Henry Cavill Joins Mission: Impossible 6
The news actually broke via writer/director Christopher McQuarrie's Instagram account (you can find a grab of the post lower down the page), in which McQuarrie, ostensibly sharing a picture of himself presumably scouting locations for the film, used the comments to start an exchange with Cavill about joining up.
And yes, while we know there will have been negotiations and deals etc, etc, it's nice to see a director having some fun with the process. Variety did a little digging and discovered that Cavill will likely play someone who works with Cruise's boss in the organisation, though whether that's still Alec Baldwin after Rogue Nation remains to be seen.
Cruise will be once again joined by Simon Pegg, Rebecca Ferguson and likely Jeremy Renner, with The Crown's Vanessa Kirby as another new recruit. McQuarrie will be calling the shots again this year with filming set for Paris, among other locations.
