Corrected entry: When the assassins are coming to kill the emperor in the beginning, watch as one slices a hole in the cloth from outside. The cloth has obviously been pre-scored to easily cut, as several mini-cuts are visible.
Corrected entry: Soon before the final battle, as the O'Connells are preparing, you see Rick and Evie emerge from behind a rock with guns in hand and cautiously watch over what is happening. In this shot, Evie is holding two pistols, and you can see that one of the pistols (should be on the the viewer's right) has a bent barrel, revealing it to be a prop.TedStixon
Corrected entry: The good guys are buried in an avalanche, then walk to Shangri La, encounter the bad guy, then travel to the Great Wall for the ultimate showdown. Their suitcases were left under the avalanche, yet they have them at the Great Wall: guns, equipment, even a suitcase of clothes.
Corrected entry: When Mad-Dog is preparing his meal in the plane, he is singing. However, just before he notices Yang's people approaching, he drinks from his flask one last time and you can still hear him singing.
Corrected entry: When Brendan Fraser gets stabbed by the Emperor's dagger/sword, the outbound wound is at his belly height. When his son checks his back, the inbound wound is between the shoulder blades, although the weapon came in straight. Had the blade entered from such a high angle, the damage would have been unsurvivable by means of puncturing heart and/or lungs.
Corrected entry: The Mad-Dog character is a continuation of a tradition in the series - in each movie, an old pilot friend of O'Connell arrives to help. Winston in the first film, Izzy in the second film, and now Mad-Dog in this third film.
Corrected entry: When Alex falls into the tomb and lands on the terra cotta horses, we hear a "clank" as if he landed on metal.
Corrected entry: Although Qin Shi-Huangdi really did oversee the first construction of the Great Wall of China (to keep out the Mongol hordes), it was originally a series of earthen embankments - not the stone wall shown in the film. (The wall as we know it was built much later.)
Corrected entry: When Evie and Rick are asked to take the artifact to China, Evie says that they are through with "espionage." However, the O'Connells were never spies; they were archaeologists.
Corrected entry: The emperor's general had all his limbs pulled out by horse at the first of the movie, but when the general is raised he only has one arm missing.
Corrected entry: Neither the emperor nor any of his soldiers are actually mummies, despite being referred to as such by the main characters several times. Given their field of work and areas of expertise, it is doubtful that they would repeatedly make such a mistake. A mummy is a body that is embalmed, dried and preserved, which the emperor and his soldiers had not gone through.
Corrected entry: In the beginning of the movie it shows Brendon Fraser fly fishing with the year stated as 1946 or similar. Then when shooting the gun at the "soldiers" he shouts welcome to the "21st" century, but that was the 20th.
Corrected entry: Although Alex is now a college student, Rick (his father) has hardly aged since the last film. They look more like brothers than father and son.
