For comparison, the first Mission: Impossible movie had a runtime of 1 hour 50 minutes - which seemed so very lengthy compared to today's nearly three-hour movie-lengths (which is something I personally never thought would become normalized, but I'm going to blame Zack Snyder for that one).

On the surface there might not be a visible link between Mission: Impossible and Land of the Dead but dig a little deeper and it's there.

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.
