Other mistake: Bonnie the Rottweiler is referred to several times by her owner Brett as a female, yet it's a male dog.
Factual error: In scenes apparently in Japan, all the cars drive on the right side of the road. In actuality, the Japanese drive on the left side of the road.
Other mistake: It is crucial to the story that Peter is terrified of moths - but when he is led through the woods at knife point by Tracey, a large moth flies around both their heads for several seconds (lured by lights of the film crew) and he ignores it, being as it's an unplanned visitor. (00:42:30)
Audio problem: Right after Det. Corelli finds the limerick in her apartment, she pulls out her gun and there is a distinct sound of what's supposed to be her cocking the hammer on her pistol. However, Det. Corelli (along with all the other cops in the movie) uses a Glock semi-auto pistol, which does not have an external hammer that can be "cocked." The sound is added artificially, likely for dramatic effect. (01:06:30)
Factual error: When Leonardo DiCaprio is arriving on the tarmac at what is supposed to be Abu Dhabi, the main (and very distinctive) Dulles airport terminal is visible in the background.
Continuity mistake: When the van stops and Fish's body is sent flying away, the position of his body on the ground differs between shots.
Revealing mistake: While Punisher is killing Pittsy, you can tell he is holding a dummy, not the real girl.
Factual error: At the end of the film, Wyatt and McQuarry each take a briefcase containing $5 million dollars. $1 million dollars in $100 dollar bills (highest denomination in circulation) weighs approximately 22lbs = 110lbs for $5 million. $5 million in $100 dollar bills is also approximately 3445 cu. in. in volume. This would not likely fit in the cases they are carrying, and would not be as easy to carry as they are.
Factual error: When Einstein is crossing a bridge on his way to the university, two German flags (black-red-gold) are flanking the bridge. The scene is set in 1914, so it should instead be the 'German Reichsflagge' which is black-white-red. Only after WW I, in August 1919, was the black-red-golden flag officially used to represent Germany. (00:38:50)
Factual error: Although correctly addressed as "captain" towards the end of the film, Richthofen continues to wear the rank insignia of an oberleutnant (lieutenant).
Continuity mistake: Torrential rain falls during the big shoot-out scene at the Ghost Market, but when Park Do-won is up on the rooftops, a 360 degree pan shot shows only light clouds that could never dump such rain.
Factual error: There is a running camera shot at the UN of national flags, the current Canadian flag is displayed but it was first introduced in 1965, the movie scene is suppose to take place in 1964.
Continuity mistake: When The Spirit is hit by the severed head in the first fight, you can see that the projectile thrown at him doesn't look like a head at all. However, it changes back when he is hit. (00:10:55)
Continuity mistake: When Jessie and Carlos walk to the church ruins, a big bruise on his nose suddenly appears for a couple of seconds, only to disappear briefly after.
Continuity mistake: In the scary door, the hay stack on the barn it diagonal, but when the aliens are attacking, the hay stack is vertical. (00:13:30)
Other mistake: When Schadenfreude is playing the piano the first time he's on screen, he starts off by playing a slow, dark piece. Right before the piece turns to a more jazzy, upbeat number, he plays three final chords: The first is higher then the others, the second is lower, and the third is somewhere in the middle. But, if you watch his hands, the first two chords were mixed up: the first chord is played with his left hand on the lower half of the piano, and the second is played with his right hand, visibly on the higher keys. This doesn't match the audio, as the chord was supposed to be lower then the first, not higher.
Other mistake: Radio aerial visible on building. (00:09:40)
Factual error: The Major and the band are (correctly) summonsed to appear before a magistrates' court for driving without insurance, but then appear before a judge in full robes. Judges do not sit in magistrates' courts.
Continuity mistake: While George W. Bush is walking along with his cabinet in Texas, on his ranch, Dick Cheney goes from walking in back of the group to being up front quickly and mysteriously. (00:25:00 - 00:26:20)
Continuity mistake: When Samir parks by 128 Randolph, he leaves the vehicle with the drivers side window down, but when the other agents pull up, the window is rolled up.
