Factual error: The season 5 episode "Designated Target" deals with the murder of a Navy admiral and the cab driver transporting him through Rock Creek Park in Washington, DC. Late in the episode, the investigators try to get a lead on another cab driver by tapping into the records from taxi meters. The problem is, DC cabs don't yet have meters. Congress banned them in 1933, but legislation passed this year now gives the DC government authority to install meters. And in fact, just days before this episode aired in Nov 2007, DC's mayor announced plans to switch from the zone system to meters by April 2008.

Other: Season 5, Episode 12, "Stakeout": The picture on McGee's camera phone is just wrong. It shows not just the man in front of him, but it also shows a hand, holding a camera phone - McGee's camera phone. In other words, the phone is showing a picture of itself and the man, instead of just the man.

Continuity: "Stakeout": When he hands Tony the autopsy report, Ducky has hair falling over his forehead, then combed back, then over his forehead again repeatedly from shot to shot.

Continuity: 5-4: Identity Crisis. When Ziva is speaking with McGee her lapel changes from being turned up and laying down.

Continuity: While Tony and Ziva are outside Ziva's apartment eating pizza, Ziva is eating the pizza in one shot with the slice in the shot, in the shot directly before this and directly after, the pizza is no where to be found and she is no longer chewing.

Continuity: Episode "Heartland": In the first five minutes of the show, after the guys are beaten up in the alley, when the black guy is laid down on the ground there is a blood stain on the wall, behind where he was standing. When the other guys go to the white guy's aid the blood stain is gone, for about 3-4 shots. When the NCIS team is there gathering evidence the blood is back on the wall.

Factual error: "Agent Afloat": Tony is reassigned to duty aboard the aircraft carrier U.S.S. Seahawk. But the ship's hull number is CVN74 - which is the U.S.S. John C. Stennis. (There is no U.S. aircraft carrier named Seahawk.)

Factual error: The episode takes place on the Destroyer DD 964 U.S.S. Paul F. Foster, but every time the ship is shown sailing past the camera you see the number 51 on the side. This is the number of the U.S.S. Arleigh Burke, a DDG not even the same class of ship.

Continuity: In one scene, McGee asks DiNozzo what Abby looks like. But jut a few minutes earlier, McGee saw her when Gibbs and his team videoconferenced with her.

Visible crew/equipment: In the scene where Tony approaches the Mallard residence by car for the first time, there is a stage light, complete with filter(?) on the balcony.

Character mistake: When Kate mentions James Bond, and DiNozzo lists the actors who have played him, he forgets Timothy Dalton. As a self-proclaimed film buff, that's not a mistake he would make.

Character mistake: In one scene, Jenny refers to "the former Czech Republic." That is the state's current name; it was formerly a part of Czechoslovakia.

Continuity: In the episode "Untouchable" (Season 3, episode 20), the camera pans across a line of several anime plushies. When the shot then goes wide, several of the plushies have either been re-arranged or removed completely, including a pink plush and the Kyogre plush. It also seems as though there are two Miroku plushies in the scene as well, one near the middle and one off to the side of the left pillow.

Revealing: When DiNozzo is watching the ship through the binoculars at the beginning, the film is run in reverse. The sailor smoking on the deck is the giveaway, as the smoke he's blowing is going into his mouth.

Continuity: When Gibbs and the team meet the sheriff and ask to be shown the crime scene, he states that it was in the Edenvale motel room 8. In the opening scene the door that the gentleman knocked on and subsequently got his feet covered in blood from the body bleeding out was room 1.

Continuity: In the Episode "Sharif Returns" When Ducky shows Gibbs the eye in the gladd vial, it alternates between being completely submerged in the fluid to sticking out the top.

Continuity: When NCIS catches the killer, the way he holds a bomb detonator changes. In some shots, he holds it with all five fingers, and in others he holds it with his middle two fingers and thumb, with his index and pinky fingers extended.
