Corrected entry: Why on Earth does the President have a British accent? This is an oddity that needed to be explained in the film, but never was. Are we supposed to assume that his parents moved to the U.S. before he was born? If that was the case, he would have lost his accent to a significant degree just from learning grammar/phonics in American schools, hanging around with American friends, etc. He couldn't have been a hermit who would've avoided these types of activities since apparently he was well-known enough to successfully run for President.
Corrected entry: In Snake's first attempt to rescue the President, he kills a guard with a thrown knife. However, the shots are out of order. First they show the guard reacting to getting knifed and the "thwip" sound of the knife going through the air is overdubbed. Then they cut to Snake actually making the motions to throw the knife. If you look closely you can see that he is making the entire throw in the second shot, his hand is not simply continuing to move after throwing the knife.
Corrected entry: Snake is supposed to bring the president back in the glider, but where would he sit? The cockpit was barely big enough for Snake to climb in alone.
Corrected entry: The film presents the idea that by 1988 crime has gotten so bad in the U.S. that the entire city of New York has to become one big prison for all the law breakers in the country. If this is so then where are all the people at? We see scatterings of them here and there and there are a few hundred during the wrestling match but that's about it, certainly not enough to represent a 400% increase in the crime rate.
Corrected entry: While trying to get a response from Washington about the code name, David 14, the aircraft, which moments later is revealed as Air Force One, finally communicates with them. The female voice says they are going to crash while spurting threats. As she is doing this, you can hear the engines of the plane getting louder and louder over the radio. It is obviously the sound of a propeller plane. Moments later, a shot reveals Air Force One as a jet engine airliner, not capable of making the sound heard over the radio. (00:10:25)
Corrected entry: At the end of the film, when the good guys are escaping with the president on the bridge -- at the command center one of the officers finds out where they are and says to the commanding officer, "they are on the 69th street bridge". They were on the 59th street bridge, which connects Manhattan and Queens.
Corrected entry: Hauk puts on Snake's wrist clock and tells Snake he has 22hrs:59min:59seconds to return with the President's briefcase, because the summit the President was going to ends in 22 hours and Snake has to complete the mission in that time. If Snake must return within 22 hours, why would his timer be set for the extra hour? (00:22:00)
Corrected entry: The scenes of various helicopters flying around are very very fake looking. In one scene, toward the beginning, the main rotor blade isn't rotating fast enough to obtain flight. (00:06:00)
Corrected entry: In the scene where Snake locates the wreckage of Air Force One, you see the right-hand side of the tail section bearing the star-spangled banner. The flag is displayed with the field of stars to the rear of the aircraft, the opposite way round from the way it is on the right-hand side of the real Air Force One.
Corrected entry: Brain tells Snake about a map he obtained indicating where all the hidden mines were on the 69th street bridge and Maggie adds that they obtained the map from a guy who got all the way across before the police shot him. How did Brain obtain this map seeing as how the guy was shot on the other side?
