Other mistake: At 1:39:14 the bomb arms, 32 seconds later at 1:39:46 (two seconds after it should have blown up) Dan and Molly jump from the helicopter. Then 10 secs later at 1:39:56, the plane FINALLY blows up after giving them those extra 12 secs to jump and conveniently make it to the pool below.
Other mistake: When Paul Blart is pwning Rock Band, the vocals shows the tambourine/clap notes. Paul Blart is doing nothing that would play those notes (singing or pressing the "a" button).
Other mistake: After Langdon saves the last of the Preferati by diving into the fountain, he heads off to St. Angelo with dry clothes. Since it is only ten or fifteen minutes later, his clothes should be soaked.
Other mistake: In the morning after scene, when the three men are sitting at the dining table by the pool with the baby, watch the extras milling about behind them. The same two people pass behind them twice from the same direction just moments apart. A little later a woman in a swimsuit walks by behind two of the characters. After a few more lines of dialogue, she is still walking by behind another of the characters.
Other mistake: When Holmes searches for hidden door after St. Thomas' death he bumps the door and it moves before he knocks on the wall to find out which side seems to be a door.
Other mistake: The Union flag in the comms room at Amundsen-Scott base is upside down. They did get the one flying outside right, though.
Other mistake: When Special Agent Bloom arrives at the beginning of the film, there's a shot of Greenly spraying breath spray into his mouth and while he does this, he's bent over, but in the very next shot, he is standing completely upright.
Other mistake: In the scene where Dillinger and his gang raid a bank and take the bank manager and a teller hostage, they come out shooting with machine guns and jump into and on the running boards of the getaway cars, all through this encounter the bank manager shows no concern for his own safety, no reaction whatsoever to flying bullets and loud gunfire, very strange.
