Revealing mistake: Lighting screens are reflected on Casey's chess opponent's glasses.
Revealing mistake: When Jack drives the bus down the alley, it knocks a series of A/C units off a building. The last one comes open and there is obviously nothing inside. (01:12:35)
Revealing mistake: In the scene where the grandfather has passed away and the family is at the hospital, there is a shot where the family steals his body and pushes it out a window. At one point in the next shot, when the family is carrying "him" to their van, the sheet moves and it's obvious the cast is carrying a bunch of pillows covered in a sheet. This also is obvious from the ridiculous way the "body" is laying on the bed prior and folds up when the cast picks "him" up and hoists "him" out the window.
Revealing mistake: When the woman is taking the pictures at the start, the camera lens has got the cover over it. (00:07:00)
Revealing mistake: In a scene where Fido is turned around, you can see a part of his head that is pink. However the rest of his body is grey.
Revealing mistake: Early in the movie, there is a visible circular, plastic looking effect on Gideon's arm as he removes the bullet with the knife. This is more noticeable around his shoulder when he cauterizes his wound with the hot knife.
Revealing mistake: When Gabriel Noone goes to see "Peter", he arrives in rural Wisconsin, looks out of the window of his car, and sees a mountain in the distance. There are no mountains in Wisconsin.
Revealing mistake: In the scene where Rooster is driving/running away from the gangsters, he is supposed to be alone in his car but in one shot a hand appears and is holding on to the passenger side door from inside the car.
Revealing mistake: Watch carefully after Angela is thrown through the windshield of the bus. There is a shot of diamonds and blood-stained glass scattering on the floor. But in reality, there is a shot of plain diamonds falling and the bloody glass is faded in during the middle of the shot. Most visible on the edges of the screen, where the pieces emerge from nowhere.
Revealing mistake: In the balcony in Havana, when Sonny and Isabella are talking about her old house, the shoreline view is not nearly similar to the real "Malecon" in Vedado, Havana.
Revealing mistake: When Vanessa comes out of the girls shower and walks to her locker, in the back shot you can quite clearly make out the strapless bra she is wearing under her towel. Also, when she lifts her arm up you can briefly see the black material under the towel.
Revealing mistake: When Solomon finishes negotiating with the diamond dealer and steps out of the car, it drives away. Presumably the shot was to appear that it pulls away and drives off into traffic, but the car doesn't clear the camera before it stops. The car just pulls ahead about 30 feet and stops again.
Revealing mistake: In the opening scene as the characters play a game of hurling, a farm is visible in the background, at the foot of the mountain. The farm buildings near the farmhouse are much too large and modern to have been constructed in 1920's Ireland.
Revealing mistake: Kirsten Dunst's contact lenses can be seen multiple times during close-ups.
Revealing mistake: There are several scenes (most notably when the group is ambushed at Mt. Suribachi) where the bayonets attached to the guns bend back and forth showing them to actually be rubber instead of metal.
Revealing mistake: Kate's birthday is July 10th. When she is (with long hair) outside on the patio with Alex, you can see their breath as they talk, and there is not a living thing in the back yard, it's all dormant (as in late fall/winter).
Revealing mistake: When Lee is being lifted into the incinerator, he moves his head, despite being dead.
Revealing mistake: Jesus is born without an umbilical cord.
Revealing mistake: When Lazarus is performing in the bar, Rae takes a drink from an empty beer bottle twice.
Revealing mistake: In many of the scenes, particularly when Michael Douglas is leaving the cafe, you can see onlookers staring into the camera. A possible explanation is that few extras were used.
