Prior to every new addition to the Fallen franchise Morgan Freeman's Trumbull has had a promotion. When Olympus had fallen he was Speaker. Then as London came down he was Vice President. Now, as Butler's 'angel' Mike Banning is about to take the fall, Trumbull is the occupant of the Oval Office.
One has to presume that should these characters get a fourth outing, he'll have to reprise his recurring role as God. Heaven Has Fallen?
With these sort of franchises one finds that there is typically a solid preliminary feature duly followed by a sequence of increasingly ropey sequels. The process appears to have ended up a bit back to front here.
Angel Has Fallen is being touted as the best of the three, and there's a good deal of truth to that, but the outrageous silliness of the format was part of its essence and something has gone missing in the furtherance of a belated seriousness. (A chunk of budget too, I would imagine.)
