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: 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: 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: 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 computer room, when the operator enters the room we see an overhead shot and the room has a highly polished floor. We see the reflections of everything, but the operator doesn't notice the reflection Hunt would have made by hanging from the ceiling. It would be very noticeable on the floor even if he wasn't looking straight down - the reflection would be well within his field of view.
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.
