Other mistake: Based on the location of the barber's chair with the picture window in Todd's barber shop and the layout of the exterior of the building, there is no possible way that the chute behind the chair would be able to dump the bodies directly into the basement without going through the center of Ms. Lovett's shop.
Continuity mistake: When Miss Gruwell and the students are discussing junior year for the first time, she has her back turned and she is writing on the board. When she writes, "First Person Na", she turns around before finishing the last word, but in the next shot, "First Person Narrative" is written on the board.
Audio problem: Just as McClane and Farrell are about to leave the Eastern Power Hub, Farrell goes on a long rant and his mouth does not match the words he is saying. [In the unrated version of the film, the rant concurs with Will's mouth movements, but the mistake is valid for the regular version.]Joel Amos Gordon
Continuity mistake: In the opening scene, just after the man is set afire he falls to the ground. Frank shoots him and while firing his weapon jams. A casing is stuck in the ejection port (called a stovepipe when it happens). After the round sticks he continues to pull the trigger and the weapon continues to fire.
Other mistake: Eddie comes to see Tom at the bathroom clean-up job and convinces Tom to confide in him. Eddie tells Tom that he'll, "See what Wallace knows". There is no character named "Wallace" - he was supposed to say "Vargas", the investigator on the case. The subtitles correctly reference Vargas.Brenda Elzin
Continuity mistake: In the scene where Dakota is having sex with Aubrey's boyfriend, it specifically shows that her bra is off. Once they finish, and she is getting off of him, she is covering her chest with the sheet. When she does this, her side isn't covered and you can that she is now wearing a black bra.Ian Mugford
Continuity mistake: The "Power Play" scene when Eric and Hanssen are in the car after a cancelled meeting (13). With Eric's line, "There's construction on E Street," the Kennedy Center appears behind his head, but in the next shot of him ("Sir, I'm SSG.,") the Kennedy Center shows up again, this time farther ahead of the car. (01:05:55)
Continuity mistake: During the complete car-bomb chase sequence towards the end of the film, Michael Clayton's car is shown in one shot without its lights on. All the surrounding shots in the scene have both cars with their lights on. This is also a slightly revealing error because it shows that they actually filmed these sequences during the day using neutral density filters. (01:41:15)
