Corrected entry: On the plane ride from Europe to America, some compartment is opened at the back of the plane and a man is dangled below the plane into the open sky. This is impossible because you would trigger an explosive decompression by opening a hatch/door inflight which would most likely suck everyone out onboard or cause serious injuries at the very least.
Corrected entry: The rabbit's foot has a Biohazard label on it. Up to the stage Hunt gets hold of it the rabbit's foot has been in the hands of the Chinese authorities, and it was created in China. Why is the sign written in English?
Corrected entry: During scene when Ethan is running across the bridge in Shanghai one of his harness wires is clearly visible.
Corrected entry: The logo for Paik Heavy Industries is visible on the side of the building which Ethan steals the Rabbit's Foot from. (Paik Heavy Industries is the name of the company which Sun's father owns in "Lost", a TV series created by J.J. Abrams.). (01:24:25)
Corrected entry: When Ethan opens the case with the G36 on the bridge, you can see that the weapon is not assembled. This includes the carry handle, which is connected to the rest of the weapon by two screws. Assembling the gun without a screwdriver in far less than a minute is quite a good timing, if not impossible. (01:04:35)
Corrected entry: When climbing the wall in the Vatican, cruise takes a photo and places it in front of the camera to blind it. The camera is pointing outwards and has no bearing on where he is going. Secondly the camera would be focused for long distance placing something that close to the lens would only be a distorted image.
Corrected entry: In the scene on the bridge when the car is blown up by a missile and Ethan is thrown into the car, this wouldn't actually happen. If he was going to get pushed away by the blast, he would have just been sent forward, as the shock wave from the blast travels straight forwards through the air. He should have just fallen towards the camera, not sideways into the car.
Corrected entry: At the Vatican party when the Chinese IMF agent spills her drink on the villain, his translator tells her to back away in English. Later when they are leaving the translator is speaking to the agent in Chinese, and interpreting for her.
Corrected entry: In the final fight, Ethan hands Julia his gun. From what he tells her, it is clear that she has never really handled a gun. He probably carries a pretty powerful gun. However, when she shoots it, Julia seems experienced in that she doesn't react at all to the backlash, which is enough to knock an inexperienced handler to the ground.
Corrected entry: At the beginning when Ethan's boss meets him at the 7-11 to give him a tape in a camera of the mission, he has 4-5 day hair growth on his face. However, when Ethan is playing the tape that was made only 11 hours before they met at the 7-11, he is clean shaven.
Corrected entry: In Shanghai, when Ethan's partners are shooting baseballs to get the security guards' attention, you can hear that the Chinese that they are speaking is not the specific "Shanghai" Chinese. They are speaking rather a Hong Kong-Taiwan tone.
Corrected entry: In the scene where Julia is giving Ethan CPR, she gives him 15 compressions between breaths. New CPR rules (I just had CPR training a few months back) state 30 compressions between breaths. Strange a nurse wouldn't have an update like that.
Corrected entry: In the final, celebratory scene, the lead female is in the IMF headquarters, meeting all the agents of this supposedly top secret organization, as well as being shown the location of their headquarters. Quite unlikely for a spy agency to reveal so many identities to a non-cleared person.
Corrected entry: The security at the Vatican is handled completely by the Swiss guards. They communicate in German, not Italian like shown in the film. They also wear distinctive medieval costumes not black suits like in the film.
