Other mistake: When Nash is put into the car and is being taken away to the hospital, there is a line of people watching him drive away. Two of the spectators are the imaginary roommate and the little girl. They are standing in front of rest of the spectators. As the car is driving away you see a female student look around the imaginary roommate to see the moving car. If the roommate can only be seen by Nash why did she need to look around the roommate to watch the car drive away?
Other mistake: When Rick and Ardeth Bay save Evie from the warehouse after Imhotep is resurrected, there are four mummies chasing them when they get on the double-decker bus. Rick shoots one of the mummies and "kills" it. He shoots another one in half and goes to the top of the bus to fight another one. The top portion of the mummy that got shot in half then fights Ardeth Bay. Evie kills the mummy that got shot in half and the top part of the bus gets torn off by the bridge and kills the mummy Rick is fighting. John stops the bus and they all sign with relief. Whatever happened to the fourth mummy chasing them? (00:43:20 - 00:46:40)
Other mistake: When the hobbits are hiding under the tree trunk from the Ringwraith in the beginning, you can see space to the left and right of the tree above them. Logically when the Ringwraith walks past the tree you would see it on the right side of the tree first, then on the left, but you don't - it looks like it walks out of the tree instead of behind it. [Confirmed on the commentaries - Elijah Wood asks his fellow actors if anyone spotted the mistake: 'It kind of magically comes out of the tree'. Sean Astin: 'You mean it doesn't pass from the other side?' Wood: 'No, it comes out from the centre.'] (00:51:40)
Other mistake: When Harry, Ron and Hermione rush to Hagrid after the end of the year exams, and Harry is saying something that ends with, "Why didn't I see it before?", Hermione is mouthing part of that line. [Emma Watson did admit she learned Dan and Rupert's lines as well as her own and found herself accidentally mouthing them.] (01:50:40)
Other mistake: When Darry is in the basement under the church, Darry is laying on the floor surrounded by a circle of sunlight appearing through the pipe. Then follows a series of cuts between Trish at the open end of the pipe, and Darry. Why do we not see a silhouette of Trish on the floor rather than a perfect circle of light?
Other mistake: When Rowan Atkinson is riding in the train, near the end of the film, he is looking out the window. He is looking forward, then quickly looks backwards. He does this several times in a row, as if trying to see things quickly as the train passes them. But, when the camera pulls back, Rowan's back is facing the direction the train is moving, thus he was looking the wrong way! You can tell by the way the scenery is moving as you look through the window. (01:28:05)
Other mistake: In the penal scene with the pyramid, Yulaw knocks a person off the pyramid, and he rolls down the steps. A short way down, he stops rolling, and you can see him push himself off another step to get himself rolling again. (01:16:40)
Other mistake: When Stackhouse and Burnett are being chased by the SAM, they pull to the right after deploying flares and you hear a voice on the radio say "Chaff, Chaff, Chaff". Chaff is a cartridge of small metal strips released as a countermeasure for radar guided missiles. These small strips add noise to the radar and clutters it up giving the pilot about 5 seconds to evade the missile. Throughout the scene, several indicators such as the flares and exploding fuel tanks suggest that they are fleeing from a Heat-seeking missile, not a radar guided one. To add to this, the voice on the radio wasn't that of Stackhouse or Burnett and was added for radio effect. (00:20:20)
Other mistake: When a glass of milk is poured, if you look closely, the glass is filled but the level of milk in the bottle doesn't seem to lower. (00:16:00)
Other mistake: When Rafe and Evelyn are on the platform by the side of the Queen Mary, the platform is going up, but the ropes are not moving through the pulleys.
Other mistake: When they are playing polo on the field one guy scores a goal then when Mary-Kate scores the goal it is the same shot - the guy on the horse is in the same place during both shots.
Other mistake: At the very beginning of the movie, when the guy throws the match into the house, it doesn't enter through the window. The match crashes and bounces back, but the fire inside the house still occurs. (00:02:40)
Other mistake: Near the end of the film, when the identity of 0001 of the CDA is revealed, number 0112 is shown both standing next to 0001 as Roz enters the room and behind Sully and Mike on the opposite side of the room. (01:16:45)
Other mistake: When Malcom X walks out on to preach before he gets shot, you can clearly see the podium with the bullets in it and chipped from the guns before he gets shot.
Other mistake: When Martin Lawrence falls over the railing in attempt to get the mysterious necklace, the camera goes to another shot that pulls away from the moat. You can see the logo on the back of Lawerence's cover-alls swimming away at the corner of the screen, when he's supposed to be under water. (00:06:15)
