Picking up from Dead Reckoning Part One, Cruise’s Ethan Hunt now holds the key to confronting the formidable AI known as the Entity, his most perilous adversary yet. The film propels the plot forward as Hunt must gather his team to locate the sunken Russian submarine containing the Entity’s source code, the key to its destruction.

A.I. was merely a creeping threat in "Dead Reckoning." Here it's a specter whose time has arrived, and that's part of what makes this a more potent adventure.

Prior to Mission: Impossible — The Final Reckoning making its debut at Cannes, star/producer Tom Cruise told reporters that he didn’t want to discuss whether the movie would be the final one. This is despite the word “final” being in the title, and all of those dang flashbacks that speak to this being the end of an era.
