Corrected entry: In the secure room, why didn't they just knock the guy out and tie him up? Then they wouldn't have had to worry about alarms at all! Claire wouldn't have even had to go inside and they wouldn't have needed all that computer technology. Ethan was hanging right over top of him and easily could have handled it.
Corrected entry: In the scene where Ethan Hunt types the email for Max, he retypes it again in German, using letters like "ä", "ö", and "ü". However, these letters do not exist in the English alphabet, which is why the laptop he's using doesn't have keys on it with those letters, (and neither does Czech by the way, for anyone who would assume that he might have gotten the laptop in Prague). To be able to type the email in German as rapidly as he did, he would have needed a German laptop, produced and sold in GermanIncognito90
Corrected entry: During the Channel Tunnel helicopter chase sequence, the colour of the helicopter changes from red to black.
Corrected entry: When Krieger drops the knife into the room William Donloe is just about to come in. When he does he looks up and the vent is back to normal screws and all. They would never have enough time to take the laser stoppers off, put the vent on, and screw it back in. Also if they did do it that quick how did they not make one sound?ShooterMcGavin34
Corrected entry: When Ethan Hunt is in the computer room dangling just above the floor (right before his sweat starts dripping down the glasses) and he is moving around trying to keep his balance, the edge of his shirt touches the pressure sensitive floor. (Granted, this was only for a second but the alarm should have gone off.)
Corrected entry: At the beginning when Jim Phelps is being briefed about the mission, the recording tells him that his "usual" team will be used, and then goes on to tell him who they all are and what their skills are. If they are his usual team, surely he would know this already? I know it tells the audience who the characters are but it makes no sense to tell Phelps that Jack can hack into any security system when he was most likely recruited for that very reason.
Corrected entry: In the scene on top of the train, Jim Phelps is opening the clip on his harness by unscrewing it. But the cable attached to the helicopter is a clip that doesn't need an opening.
Corrected entry: Why does the CIA go to all the trouble of putting lasers across the air vent into the secure room, wouldn't it be cheaper and easier to make the air ducts too small for anyone to squeeze through?
Corrected entry: During the scene where Ethan is hanging in the bank, he can't talk or he'll set off the sound-sensor; he can't touch the ground because of the weight sensor; and he can't cause the room to get too hot because he'll set off the heat sensor. If there were a vent, the temperature would most likely change. Why isn't there a motion detector?
Corrected entry: In the scene where they go to the mainframe to get the NOC list, there is, of course, an extremely secure computer. However, with all these security precautions, somehow, it allows logins when the security system knows that no-one can be in the room.
Corrected entry: In the scene were Max tells Ethan the combination for the money, the code is 3-14, in the bible Job 3:14 says "with kings and their advisors whose palaces lie in ruins" possibly referring to Phelps who was the king of the operation and Claire and Krieger, his advisors.
Corrected entry: When Ethan is hanging from the ceiling of the computer room suspended just above the floor he watches sweat build up on the corner of his glasses then drop. When he catches the drop he is seen to breath a sigh of relief, then there is a cut to Luther also breathing a sign of relief back in the control position. Luther would not have been able to see the drop build up on the glasses from a camera in the glasses.
Corrected entry: Why is there a sign inside the secure room saying whether the security measures are on or off? The only people able to read it would have to be in the room, and anyone supposed to be there would know they were off, and there would be no reason to put a sign up for anyone not supposed to be there.
Corrected entry: The vents that Hunt and his sidekick crawl down at CIA Headquarters are standard galvanized iron box vents; they are very common in the building trade. Try walking or crawling down one - you'll make a noise like the sky is falling down. People will be able to hear you for miles. Every person in that building would know somebody crawling about in the vent system. (This error applies to dozens of films, not only this one.).
Corrected entry: When Ethan runs out of a restaurant after blowing the large water container with fishes with his chewing gum-bomb, you can see all the fishes fall to the floor as water rushes outside the restaurant. No even one fish moves. The explosion wouldn't have killed them because the tempered glass and the water have more density than air, so it would break the glass, but the blast would go the other way. They drop dead. (Fake ones for the activists, maybe.)
Corrected entry: In the scene where Tom Cruise and Vanessa Redgrave are in her chauffeur-driven car, he "sets his price" for the NOC list, stating that he wants "two million dollars in bearer US Treasury bonds, with all coupons attached". The film is set after the fall of the Berlin Wall and after the Eurostar started running, that is no earlier than the nineties; however, the U.S. Treasury ceased to issue bearer bonds in 1986, so it would be impossible to find by that time, those bearer bonds, with "all coupons attached" (unless they can locate a lazy bones or neglectful investor which has let several years go by without collecting his coupons).
Corrected entry: When Hunt and Krieger are crawling around in the duct work to break into the computer room, the arm that removes the vent cover is visibly that of a black man. Both Hunt and Krieger are white.
Corrected entry: Liverpool Street Station is shown as more or less deserted in the hours of daylight. The only way this could be achieved in real life is by phoning in a bomb threat.
Corrected entry: Claire leaves the fire fighter uniform in the closet but is seen wearing it again in the truck while leaving.
Corrected entry: Why on earth would the NOC computer be left online while the operator is out of the room? A simple logon card on a chain around his neck could be used, like most government departments do. Why would such a sensitive computer have a CD burner attached?
Corrected entry: When Ethan is hanging in the room trying to get the NOC list the guy that is supposed to be working in there comes back and sits down, and just before he pukes his brains out his eyes look straight up towards Ethan.
Corrected entry: Why, in the most secure computer room you could find, with all those detection devices, did they not install video cameras?
Corrected entry: When Ethan is in the computer room, why doesn't the alarm trigger when he types on the keyboard?
Corrected entry: How will the death of Jack be explained or disavowed to authorities, since he will be found with all his technological stuff, including the laptop with all of the IMF information?
Corrected entry: When stealing the NOC list, why worry about raising the temperature of a temperature-controlled room? If your body temperature can even raise the temperature of such a large room significantly, wouldn't the air-conditioning just kick in to compensate and keep the temperature of the room constant?
Corrected entry: In the scene where Ethan is in the NOC list room, when the camera changes to Krieger you can see a rat approaching. Krieger has noticed this rat. After you see Ethan come all the way back up and nearly into the hole the camera changes back to Krieger and there is a dead rat behind him. How did Krieger manage to kill that rat if both his hands were doing something?
Corrected entry: Ethan doesn't wear glasses so why did he choose to wear some when he was hanging in the room trying to get the NOC list?
Corrected entry: The only place in London with that much grass around Tower Bridge is the Tower of London itself. I don't think whoever runs it would be happy to have a chopper within its walls.
