Revealing mistake: When the spear handle is protruding from Hector's shoulder, the area of the armor around the circular wound is clearly visible and it is in perfect condition. There is no tear in the armor whatsoever, around the wood, which would have been necessary to allow the wide spear tip to penetrate the armor and actually enter Hector's body as it did.

Revealing mistake: Just after Harry attacks Snape at the Shrieking Shack, he insists on knowing about Peter Pettigrew. In the next shot, as Lupin says, "He was at school with us. We thought he was our friend," there are wedges under the wheels of the piano, however, in the following shots they're gone. (01:34:10)Super Grover
Revealing mistake: When Violet and Klaus make the tent inside their bedroom in Count Olaf's house, they set up the light with the faces of their parents on it in front of it. Except when it shows the shadow of the object outside the tent, the edge of the picture frame isn't showing when it should. (00:21:40)
Revealing mistake: Very near the end of the movie, when the NOAA director is viewed in the helicopter as it approaches NYC, the image is reversed, verified by the David Clark logo on his headset being reversed. There are two different shots of this just a few seconds apart, and they are both reversed.
Revealing mistake: Just before the Roman soldiers pressed Simon of Cyrene to help Jesus carry the cross, Jesus has fallen and we see that the bruised and swollen-shut eye is now his left. The shot changes and when it comes back to Jesus his right eye is swollen shut again. The film must have been flipped.
Revealing mistake: About 30 seconds into the movie, when the camera is panning down the flight status board, the letters are flipping through to form the correct words. However, the board is digitally animated, and some of the sequences of letters scrolling (such as one square going from L to M to N) loop without making any sense, like in the line above the yellow "The /Terminal" (U, V, W, U, V, W, U, V, W.).
