I was (once again) in the mood for a Big Dumb Movie and went for the sequel to Olympus Has Fallen, which I watched last month.
Slight spoiler: the setting is … London, England! World leaders are in town for the funeral of the unexpectedly-dead Prime Minister. But it's all a plot, meticulously designed by a terrorist/arms dealer who seeks revenge for a drone strike on (what turned out to be) a wedding party, killing his just-married daughter. I think. Because basically that's just the excuse for staging a bunch of explosions, gunfights, car chases, more explosions, fisticuffs, helicopter crashes, …
But the first twenty minutes or so of the movie are relatively peaceful (except for that spoiled party), with establishing family man/Secret Service agent Mike Banning's (Gerard Butler) relationships with his pregnant wife and the President (Aaron Eckhart) and Vice President (Morgan Freeman).
But once that's done with, we are never more than a few minutes from impressive amounts of violence and action. Mike has to get the President to safety, but that's made extremely difficult by the (literally) hundreds of terrorists with prescient knowledge of security weaknesses, escape routes, and safe houses. There's a mole, of course.
