Before Christopher McQuarrie joined the Mission: Impossible franchise, each movie felt like a largely standalone feature, with Ethan Hunt and Luther Stickell being the only recurring characters. But starting with Ghost Protocol, and to a larger degree Rogue Nation, these movies have become more connected to one another, and Fallout in particular saw the most amount of established characters returning, including Ethan’s ex-wife, Julia Meade. The fact that these next two Mission: Impossible movies are being filmed back-to-back suggest that those stories could be even more closely tied together, similarly to what Marvel did with Avengers: Infinity War and Avengers: Endgame. Assuming that is the case, doesn’t it make sense to end the Mission: Impossible franchise on the biggest bang possible rather than trudge to the finish line with a lesser product?
