Corrected entry: When Ethan pushes the bulletproof box over, the hoses that connected the box to the gas canisters are gone. (02:01:30)
Corrected entry: When Hunt stumbles over the front of the car in Morocco it's facing to the left, but when he drives off it's now facing to the right.
Correction: The car doesn't change directions. When he jumps over it the camera is on the left side of the car. When he drives off the camera is on the right side of the car.
Corrected entry: When Brant runs out of Kings Cross station he's not wearing sunglasses, but when he stops running in the underground carpark he's wearing sunglasses.
Correction: Brant is wearing sunglasses as he runs out of the station with Ethan, when the camera pans to their faces in the underground parking lot Brant is still wearing the same sunglasses.
Corrected entry: Ethan puts Benji's identity card (for the underwater safe scene) in a shoulder pocket in his wetsuit. He then pulls it out of a pocket on his leg.
Correction: Ethan puts Benji's identity card in his left leg's pocket right at the start.
Corrected entry: Hunt cannot use metal air tanks to enter the server because they would be detected. It would be perfectly possible to use low pressure plastic ones - they wouldn't hold much, but enough for a few minutes.
Correction: Low pressure diving equipment would still utilise some metal components.
Even a lemonade bottle would still hold a lungful of air.
Corrected entry: When Ethan and Benji go to Morocco, no one would know what the security card would look like or how it's programmed for them to make a copy to fit Benji's profile. Also issues with acquiring the BMW used to jam the signal at the gates, as the car is supplied by the IMF, which Ethan is no longer a part of, and Benji couldn't ask for it, as that would open him up to too many questions.
Correction: They knew how the system was designed, they just had trouble accessing it. As for the car, the Syndicate could have provided it (since Ilsa was working for them), rather than the IMF. Ilsa simply took advantage of Ethan's skills to get hold of the information from the vault. The plan itself was already in place (she was training for the diving section of the mission).
After the assassination, Ethan gained access to an IMF safe house (boat) and cache. It is entirely reasonable to assume he was aware of another in Morocco where they acquired the car.
Correction: The glass box has an open grate in the bottom, hence the cage would not be connected to hoses as the gas could seep in from external canisters.
