Olympus Has Fallen last night. If you can maintain some suspension of disbelief regarding the setup and a variety of issues, how they could organize such a well supported, undetected group to assault the White House, and how I seriously doubt, in an emergency, they would take foreigners into the bunker along with the President, it was a decent action flick. IMO, the key to implausibility of this story is not that a group, with the luxury of a circling gatling gun C130 overhead, could not attack and even get into the White House, it was the bunker access.
Besides the implausibility of the "Cerberus System", I don't see the U.S. moving it's fleet, abandoning S.Korea or neutering it's nuclear arsenal to save the President. In the situation portrayed in this movie, I believe he would be expendable. So I got a little perturbed when Morgan Freeman kept saying "we have to save the President!" as if that was more important than regional stability and National defense. And the President "give them the code"! Noted, the lead character reminded them that there was an interim functional President.
One other possibly serious plot discrepancy, (I got up for a drink) how did they get Cerberus System activated with only 2 of the 3 codes I thought they needed?? And that automated Hydra 6 System, if the terrorists were not have supposed to have brought it with them, (seemed to massive to tote in, along with the rising platform and integration into the White House structure) why did the Whitehouse not use it to shoot down that pesky C-130, because flares don't stop bullets. Ok, dependencies mounting... but nice integration with the White House location. I'm surprised they let them trash it in that fashion for a movie.

Apparently for the movie they built a White House Replica in Bossier City, Louisiana near Shreveport. (
