The latter Mission: Impossible movies have been pushing for more of a team dynamic than a one man against the world type of movie and have improved for it. In fourth and fifth movie they introduced William Brandt as played by Jeremy Renner but fans were surprised to see that Renner wasn't making an appearance in the sixth installment of the movie.
Director Christopher McQuarrie spoke Empire about how we almost got a cameo from Renner.
Warning for very minor spoilers for the beginning of the film.
"I had this whole idea that the movie would start with the death of a team member," McQuarrie said. "And of course the first team member that's always the first guy we talk about killing is Luther. Luther died in the first movie, and he quite famously said to Tom Cruise, 'Hey man, how come the brother's always gotta die?' And Tom said, 'You're right.' He was like, 'Why do I gotta be the bad guy?' And they made Luther nefarious and then suddenly a good guy, and six movies later it was the smartest question anybody's ever asked Tom Cruise […] So I said to Jeremy, look we can't kill Ving, it's never going to work. No matter how many movies into it, it's always going to be the same thing. You killed the black guy. And we didn't think the movie could recover if you killed Benji."
McQuarrie went on to say that he thought about killing Brandt and made the offer to Renner to come in and shoot for three days. Renner, who was busy shooting the Avengers movies at the time, turned McQuarrie down.
"So I said to Renner, 'Hey listen, I have this idea for an opening sequence where you sacrifice yourself to save the team, and that the mission-gone-wrong not only involves losing the plutonium, but involves the death of a team member.' And Jeremy was like, 'Thanks, but no thanks' […] He was smart not to take the short paycheck for three days of work and getting blown up."
The stakes of Mission: Impossible – Fallout went plenty high without any blood on the ground in that opening scene and now it leaves the opportunity for Renner to return to the series should they decide to make another entry in the series. The box office and reception for Mission: Impossible – Fallout are both pretty positive so unless star Tom Crusie decides he doesn't want to do another one we can assume a seventh entry in this series is on the way.
Summary: Ethan Hunt and his IMF team, along with some familiar allies, race against time after a mission gone wrong.
Mission: Impossible Fallout, directed by Christoper McQuarrie, stars Tom Cruise, Simon Pegg, Rebecca Ferguson, Henry Cavill, Vanessa Kirby, Alec Baldwin, and Angela Bassett. It will be released on July 27th.
