While Olympus Has Fallen was in its main theme and overall plot quite similar to many action movies of that kind, there were two particular scenes that I understood as direct references to two genre classics:
The scene where Banning meets the traitor Forbes reminded me very much of the scene in Die Hard where McClane meets "Bill Clay".
The finale was very similar to the ending of Under Siege, from the knife fight with the bad guy to the following scene with Banning being instructed how to enter the abort code while the whole command center is listening in suspense.
Now of course there were other similarities and such movies usually follow rather characteristic formulas. But those two similarities struck me as just too obvious and direct references to be just dismissed as the usual genre ingredients. So is there any other evidence or even word from the filmmakers that those two references were actually made on purpose or that they were directly influenced by those other movies or am I just overinterpreting things here (given that I've seen said movies a million times)?
