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. (02:01:20)
Revealing mistake: As the grating descends on Raoul, in two shots, large bubbles are flowing downwards. It's obvious, the film was reversed. (01:59:15)
Revealing mistake: When Noah and Allie meet outside the movie theatre and later dance in the intersection of the streets, the viewer can see their breath. It is very cold outside and Noah is wearing a heavy jacket. Summer in South Carolina is oppressively hot, even at night. (00:17:00)
Revealing mistake: When Eli and Klitz are being chased by Mule, Eli and Klitz go over the railing and land on the table. After that when Mule lands on the table you can see the table break a split second before he lands on it.
Revealing mistake: When Arthur is giving his speech before the last battle, in the background are three radio towers. You never know Arthur might need a radio to find out tomorrow's weather.
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: In the beginning, there is a scene where Sen. Shaw is watching Raymond make a speech on a TV screen. It was obviously put in in post-production because the aide immediately next to the screen is nodding and clapping in agreement at inappropiate times.
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.). (00:00:30)
Revealing mistake: Near the end, when Morgan Spurlock says "Why not do away with your Super Size options?" the water condensation runs UP the drink. (01:34:00)
Revealing mistake: Early in the film, when Hughes and another guy are walking past one of the replica WW1 aircraft used for the "Hell's Angel" scenes, you can see the ends of the cylinders of the modern air cooled engines they used to power it. The original aircraft (SE-5A) used a water cooled V8 which wouldn't have been visible.
Revealing mistake: In the scene where Evan wakes up and notices that he has no arms, right when you see the stubs you can see a faint shadow moving next to his head and moving on the headboard. This shadow is the shadow of his hand before it was digitally removed. (00:29:15)
Revealing mistake: When Ms. Norbury spills coffee all over her shirt, you can see the hand that is to the left is pulling her shirt up with her sweater and rapidly lets go.
Revealing mistake: When the kid and the coach are throwing the little boxes of corn flakes in the air the kid's last couple of boxes were pre opened.
Revealing mistake: Throughout the extended scene where Ralph was training with Father Hibbert in pouring-down rain, both characters' faces were completely dry when they should have been completely wet.
Revealing mistake: Towards the beginning of the movie, young Alexander tames a horse and then jumps on the horse and rides off. He is supposed to be riding bareback, but in one of the shots from a distance, you can tell that the actor's feet are in stirrups.
Revealing mistake: In the beginning of the movie, there is a shot of Largeman opening a medicine cabinet. If you look on the mirror as he opens it, you can see the cut out of where the camera is hidden in the wall. This is pointed out by Braff in the commentary.
Revealing mistake: If you watch Herb's wife Patty drink her hot chocolate, it is very easy to see that the cup is empty.
Revealing mistake: As Ana is driving away from her home, when we see her car driving from a shot high above, we see a car crashing in to a gas station making a huge explosion. However the trees a few feet away from the explosion don't move. The shockwave would have made them react at least a bit. (00:09:20)
Revealing mistake: When Gene's bodyguard (the one with the moustache) shoots Slasher and Duke, just before Slasher is shot the bullet hole effect is visible on her forehead (sightly concealed by make-up) just before the actual 'shot'.
Revealing mistake: In an early scene Cole and his future wife watch fireworks over Paris through a doorway overlooking a balcony. The explosions are reflected on the glass of the open door, which is at an angle to the POV. But the CGI fireworks and their reflection in the glass are squashed to fit into the foreshortened pane of glass. In reality the reflected image would be like any mirror, with the image inverted left-for-right.
