Factual error: Captain Stanley says of Australia "What fresh Hell is this?" The scene takes place in the 1880s, yet the quote is attributed to Dorothy Parker, who would not have been born yet.
Continuity mistake: In this scene we see the police car chasing Wesley Snipes' car. During the chase we see that Snipes' car has sustained heavy damage to both front doors, then when the car finally comes to a stop after the chase, it has repaired itself. The doors are repaired with only slight damage to the right front.
Visible crew/equipment: Near the very end of the film when Tommy Lee Jones is standing in the ruined building surveying the scene where Melquiades is to be buried, a crew member in a blue shirt can be seen crouching down against the wall in the background.
Other mistake: When they open the bag of money and fan through it, you can see the back bill says TWELVE - as in a twelve dollar bill.
Continuity mistake: During the chase after John witnesses a woman get kidnapped, one of the thugs shoots out of the driver's side headlight of his blue van. A couple of shots later, the headlight is back in and it's there for the rest of the chase.
Continuity mistake: At lunchtime, only Martha has a large drink with a red straw, but some views show a second red straw behind hers. In the distant view when lunch is almost over, there is only one red straw/drink on the table. (00:06:27 - 00:07:28)
Continuity mistake: After Suit finds the body on the rocky shore, it cuts to the police sedan that Jesse is driving. However, in the shots from inside Jesse's vehicle, as Jesse passes storefront windows, the reflections reveal that Jesse is actually driving an SUV-type vehicle down the street. (00:01:50)
Continuity mistake: When Nisha is talking with Clayton outside his house she leaves in her car and closes the door twice.
