Getting Off - S4-E16
Continuity mistake: When Jamal is been helped out of Ed Burnell's wrecked BMW 7 Series, the wrecked car is a late 80s-early 90s E32 model. However when Burnell was driving it at the beginning of the episode, it was a newer late 90s-early 00s E38 model. Again, the production crew couldn't afford to wreck a brand new car so an older one was substituted.
Continuity mistake: Sam's matchbox, in the interview room, changes from face-forward to back-forward several times.
Dead Ringer - S4-E20
Continuity mistake: When Nick is showing the burger guy the pictures from the ATM, he holds one up while facing the see-through window. He turns and puts it on the table and it's a completely different picture.
Continuity mistake: When Brass and Grissom first enter the house of Ken Willard (the guy in the Polaroid), and Greg makes a noise at the door, the two of them turn around to see him. Then the angle changes, and they turn around again, repeating motion.
Continuity mistake: When Grissom, Brass, and Greg go to the house of the guy in the Polaroid, Brass picks up a credit card from a table. First, he is holding it by his middle finger and thumb from the back, then the shot changes to a close-up and he is holding it with his index finger and thumb along the sides. Then, we return to the previous angle and he is once again holding it with his middle finger and thumb from the back.
Continuity mistake: As Nick and Warrick are assessing Wendy Garner's travel path and find that there are 14 minutes unaccounted for, the screen says "Wendy Jones' House". Her last name is Garner, her old last name was Clancy, and her fiancé's last name is Lanner, therefore it makes absolutely no sense to have "Jones" on the screen.
Continuity mistake: Season 5, episode 11 'Who shot Sherlock?'. In the scene where Sara Sidle sits down at the victims desk and computer, in the first shot you see the top corner of the notebook lid, saying IBM, then when you see the screen it says DELL on the bottom of it, and then in the next shot you once again see the lid with the IBM mark.
Continuity mistake: In the scene where the CSIs are first crawling into the nursery, you can see Grissom's ungloved hand, which was gloved before entering and after exiting the crawlspace. (00:19:00)
Continuity mistake: When Sara and Jim Brass are interrogating Tonya you can see Jim open up her cell phone behind Tonya. Than they do a wide shot and Jim opens up the phone again.
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)
Big Middle - S5-E16
Continuity mistake: Season 5 Episode 16 "Big Middle" Sara Sidle marks a triangle on a bed sheet around evidence and then proceeds to cut along the inside of the triangle lines in order to remove the evidence from the sheet. In the next shot, Sara is shown removing the cut out from the sheet, which now has been cut along the outside of the triangle lines.
Continuity mistake: The Pontiac Fiero that is seen underneath the Hummer is a different (but newer) model than the one that was briefly seen driving away from the taco stand.
Continuity mistake: In the opening scene, the female student is wearing green panties. When the two bodies are found, she is wearing red panties. It was a murder behind a locked door, so no one changed them for her.
Suggested correction: The girl had green panties with pink or red strings. When she was found, all that was visible was the string.
Continuity mistake: Season 5, Episode "Grave Danger" (parts 1 and 2); there are a number of shots of Nick in the grave which don't match what the CSI team see via webcam. For example when he is speaking into the tape recorder he is holding it above his head from the view inside the grave, but from webcam he is holding it further down.
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 Grissom is on top of the box, talking to Nick, and he tells Nick to put their hands together, you can see that from shot to shot, the alignment of their hands changes. In one shot (from Nick's angle), Grissom's hand is higher than Nick's, as well as Grissom's index finger lines up with Nick's middle finger. In the next shot, their hands line up perfectly. The alignment changes throughout those few shots.
Continuity mistake: There are some major continuity errors in the rescue scene at the end: First, the loader is missing from the side of the grave during several of the shots. Second, the rope changes position. The CSI crew is shown manning the rope, which is running parallel to the ground, ready to pull Stokes out of the grave. (There is a physics problem with this anyway.) The next shot is a close up of Grissom and Brown and the rope is now going up at a severe angle. Brown can barely reach it. (The stuntman can only be pulled out from above, the aforementioned physics problem, and the rope is leading up to the rigging.) Third, immediately after the stuntman is pulled from the grave and right before the explosion, there is no one and nothing near the grave. The loader ends the scene right where it started: on the edge of the grave, bucket up, lights on.
Room Service - S6-E2
Continuity mistake: When Warrick is in the hotel room at the start, the corpse's eyes alternate between open and closed.
Continuity mistake: When Nick "attacks" the kidnapper in the interrogation room, a single tear falls down from the boy's left eye. When the shot changes to a different angle, the tear is coming down from his right eye.
Continuity mistake: While Kelly is being interrogated in the interview room by Nick, her hair changes between shots. Close-up it hangs loose. In the wide shots both sides are tucked behind her ears.
