Continuity mistake: When Grisson gets on the vibrating bed, in the close up shots he is sitting with his neck even to the top of the headboard and no pillow showing. In the wide-angle shot, he's hunched down lower with a lot of the pillow showing above his shoulders.
Continuity mistake: During the scene where Catherine goes to her father for the money to save Nick, the character played by Frank Gorshin is talking. At one point he is seen from the front and puts his hand up to fiddle with his collar/neck. The shot changes to a side view and both of his hands are suddenly in his lap with no time for him to have put his hands down.
Continuity mistake: When the victim is hit by the car, it shows him get run over by the front right wheel of the limo. Later on, the body is "thrown 45 feet" and is ahead of the stopped limo.
Big Middle - S5-E16
Continuity mistake: The board behind the oddsmaker keeps changing. At the beginning, he has crossed out the odds on the game between Miami and Memphis from 5 to 7 1/2 to 10 1/2. When Brass comes in, the board is only showing 5. It then changes every time it switches from Brass to the oddsmaker- it will show the 5 crossed out and then not crossed out the next time. Finally in the final shot, it shows the board without the 1/2 after the 10. (00:17:15)
Continuity mistake: When Brown talks to David, David pulls out a pelvis from a vat of acid, saying he's cleaning it. In one shot the pelvis is hanging off the lower of the tongs, but in the next shot it's clamped between the tongs. This series of shots occurs a couple times during the conversation.
Continuity mistake: When Grissom first arrives at his own home, he turns on his stereo and adjusts one of the levels. In one shot, he uses his left index finger to push it up, but in the next, he is moving it with his right index finger and thumb.
Plot hole: The bodies were pink because of exposure to the lower temperatures created by the dry ice venting into the room. None of the CSI team noticed a chill when they entered the room? None of them noticed the bodies were cold to the touch? No one noticed that the body or liver temperatures didn't match with the estimated time of death?
Built to Kill (Part 1) - S7-E1
Continuity mistake: When Doc Robinson is checking the mouth of the suicide victim, when he opens the mouth you see a chipped tooth on the bottom middle, when they show the zoom in to see the sesame seeds there is no chip.
Factual error: Sara calculates the time needed to sabotage the tire at a minute to a minute and a half. That is, remove the valve core, allow the majority of the air to escape (cannot pour anything into the tire while the air is escaping) pour in enough chloroform to sabotage the tire, replace the valve core, and air the tire to pressure. Even with an industrial air compressor, it would take over 2 minutes to air that tire to full pressure.
Continuity mistake: In this episode, Catherine is sent to Miami on a lead of a missing child. There they find a car in a swamp, and when the pull the car out and open the door, a female body falls halfway out. When this happens you can see the woman playing the victim breathing. You see her stomach moving up and down.
Continuity mistake: In the Season 8 episode "Goodbye & Good Luck," near the beginning, Sara and Warrick bump into each other and Warrick drops his medicine. During their conversation, Warrick squeezes Sara's shoulder and then drops his hand. The shot instantly cuts to a view from behind Sara and Warrick's hand is back on her shoulder with no time (or reason) for him to have put it back.
The Finger - S2-E14
Continuity mistake: When Catherine goes into the diner with a man and Sarah is sitting talking to her date, in one shot they are talking and in the next immediate shot he has a cup to his lips.
Revealing mistake: When Warrick takes out the contents of the wallet, he removes a few 100 dollar bills. If you look carefully, you can see on the top bill it says "For Motion Picture Use Only."
Revenge Is Best Served Cold - S3-E1
Other mistake: Stokes tells "Michaelangelo" he is looking for a blue Honda, blue rims, blue tint. The picture Michaelangelo shows Stokes and Willows is an Acura RSX, not a blue Honda. (Note: The red Honda that the victim was driving is not the one that Stokes is looking for.) Just because the two car brands are owned by the same parent company does not mean that they are interchangeable when describing them. You certainly couldn't call a Cadillac a GM and not be considered wrong even though they are both made by the same parent company (GM).
Factual error: Brown and Stokes mix up enough ballistics gel to make a life-size dummy to test their theory. The entire production (getting a mannequin, making a mold from the mannequin, etc,.) takes place in one shift. Ballistics gel needs to cool in a fridge, or on ice, (32-41°F) overnight. That alone eliminates the possibility that it was done in one shift. http://www.recguns.com/Sources/XD3.html.
Cats in the Cradle... - S2-E20
Deliberate mistake: A father, daughter (both construction\demolition experts) and the boyfriend try to frame the husband for attempted murder by planting a pipe bomb in her (wife\daughter\girlfriend's) car. The bomb is a stick of dynamite inside a pipe with 2 endcaps on it. A pipe is used to hold a improvised munition together: i.e., homemade explosives, or something like Anfo. The pipe provides the casing for the explosive material. Or, it is used to keep the shrapnel fragments around the explosives (like nails or pellets around a stick of dynamite). For dynamite, you simply drill a hole (in rock, in concrete, in whatever.) and drop the stick in. It needs no extra casing. The family would have known that. But the CSI crew needed some evidence to analyze and the blasting cap + detonator circuit would have given them nothing to study. The endcap with the hole drilled for the blasting cap was the case solver.
Continuity mistake: Nick counts the bullet holes in the rabbit sign used for target practice and says there are only 9 holes. It shows a flashback to the guy shooting and he shoots a tenth hole in the sign near the rabbit's right arm. This hole is not shown on the sign Nick looks at.
Continuity mistake: When Warrick is talking to Dr. Robins, his collar changes place. During the close-ups, only the right side of his collar is tucked in. During shots farther away, both sides are tucked in.
Factual error: When Captain Brass is in the travel agency and talking to the woman who works there, they access the last bookings taken by the victim. 4 lines up from the bottom, "Bob R" seems to have booked a return trip to Paris in Germany, when in fact Paris is in France.
Revealing mistake: Mickey Dunn is played as a young man by Rik Young with hazel eyes. His eyes are much darker than the older Mickey Dunn, played by Roger Daltrey. Roger Daltrey's eyes are notoriously as 'blue as the sky'.
