Deliberate mistake: At the end just before the president is killed he fixes his tie, but it keeps on getting fixed to messed, to fixed, etc. Deliberate homage to "A Few Good Men", but worth looking for nonetheless. (00:28:15)
Deliberate mistake: Practically all movies incorporate the name of the movie within the dialog. However, they must remember the English language and tense agreement. On at least two occasions, Fishburne says "Come on Dodge, lets FLED." If they were so interested in incorporating the name within the script, they should have named the movie FLEE.
Deliberate mistake: Just before Donald has a fight with Jack at the end of the film, we see Donald jogging down a flight of stairs to escape the building. Then after a bit of a punch up with Jack, we see Donald running back up the same staircase to escape Jack, but when he reaches the top it turns into a dead end. There is nowhere that Donald could have came from when we see him coming down the stairs. (01:19:35 - 01:20:35)
Deliberate mistake: When the media truck follows Mel, he comes to a traffic light and stops. When he throws away the van's keys, he speeds off from the intersection. Why are the cars at his left not driving? They look like they have parked there and with no drivers present in the car. Weird for a very busy road.
Deliberate mistake: By the time the island blows up after Drax is destroyed, don't the explosions seem to move very slowly at the shot where Zane dives into the water?
Deliberate mistake: When one of the captains throws the grenade while Mason is in the bath, it coincidentally rolls to a left into the bathtub area, instead of rolling straight.
Suggested correction: The grenade isn't a sphere. It is obviously lopsided, and would tend to not roll in a straight line. Although it is probably exaggerated for the scene.
Deliberate mistake: The disco ball doesn't start reflecting the sunrise until after the lead characters get out, even though it should have began to reflect light right when the door opened.
