Character mistake: Throughout season 3, whenever someone visits Henry in prison, the word "VISITOR" on their visitor tags is misspelled as "VISTOR."

The Magician - S3-E4
Revealing mistake: When Oliver meets Thea at the Grind and Jot Cafe (Which looks unsurprisingly like CC Jitters) you can see the cups on the table are from CC Jitters. (00:20:50)

Character mistake: They are in the interrogation room questioning the fiancé of the scientist Natasha when the captain says, "the blood we found at the scene of your fiance's murder, it didn't belong to Bobby Cordero." The characters name was Benny Cordero, which the captain says correctly a few lines later. (00:33:25)

Death at Victoria Dock - S1-E4
Character mistake: Fisher refers to some characters as speaking "a Slavic language." The characters are Latvian anarchists. Lettish (aka Latvian) is a Baltic language, not Slavic.

Continuity mistake: When Bentley says how Maple Man can "gobble my knob", he briefly pauses between each word. When Theresa then plays back Bentley's confession, he says "gobble my knob" without pausing. (00:18:58)

Continuity mistake: In the final scene, John Ross decides to drink some of the whiskey from the bottle that his father, J.R. Ewing, left for him. The bottle of whiskey is about half full, filled to just about the bottom of J.R. Ewing's signature on the bottle. As John Ross reaches for the bottle, it is now suddenly only about 1/6 full compared to the half full it was from the previous shot. The level continues to move up and down. (00:41:45)

Continuity mistake: After their victory, the Turtles are celebrating and partying. Just before the episode ends, Leonardo is dancing on a white mat and doing the moon walk. It cuts to a higher angle and suddenly the white mat vanishes.

Revealing mistake: When the simulation starts, Wolverine is shown stabbing a guy with his claws. There is a blood splat on the wall, but there is no blood on Wolverine's claws. (00:02:15)

Factual error: In the scene at O'Hara airport the paramedics meetup with a TSA officer. The TSA officer has a gun as a part of his uniform. TSA officers do not carry firearms. In addition, the CBP officer in the scene does not have on a proper CBP uniform. The CBP officer uniform has rank epaulets and officer has no epaulets, and the CBP uniform doesn't have a bar tie clip and the gun belt buckle is brass not stainless metal. (00:42:00)

Continuity mistake: When Lin lifts the rocks around the house in the final scene, there are eleven of them. But in the last shot, there are only eight rocks.

Factual error: Waterloo County Fair labeling shown at least twice. Waterloo is not a county. Black Hawk is the county and Waterloo is the city in Black Hawk County.

Factual error: When the presidents are coming together, there are pictures being taken with flash photography, which would not be possible in a world without electricity. (00:34:15)

Continuity mistake: After lying about his wife to Lauren, Ryan shouts after her as she gets in her car. From the back he has a pen and paper in his right hand, but in the front shot the paper has vanished.

Factual error: The battalion commander wears the correct crown and pip of a lieutenant-colonel, but the four cuff rings of a full colonel (lieutenant-colonels wore three).

Factual error: Noticed this watching season 2, and I assume it was also the case in season 1. The entrance of the Miramar Playa has flags from various countries flying. One of them is the Canadian flag with the maple leaf. Wrong flag. In that period the Canadian flag was the "Red Ensign", or "Dominion Flag." The maple leaf flag wasn't introduced until 1965.

Continuity mistake: When Buzz and Provenza race out of the squad room to follow Rusty in the frantic search for Stroh, Buzz is in shirt sleeves with no tie. However when they arrive at their destination Buzz is wearing a coat and tie.

Factual error: The General wants to do his interview by the TV so he can watch March Madness at the same time. When the interview is about to begin, it shows a Kentucky game being played on Kentucky's home court. Teams cannot play on their own court during the NCAA Tournament. (00:40:50)

Fruit Picking Day/Daniel Is Big Enough to Help Dad - S1-E11
Revealing mistake: When Daniel picks up the can of blue paint, it passes right through the cans of yellow and red without bumping them.

Factual error: The depiction of the hanging is completely inaccurate. By the 1890s, the gallows at Newgate were housed in a room within the prison, not in the courtyard. Prisoners' wrists and legs were pinioned before they were hanged, not left free as depicted. The long drop was used in Britain from the 1870s, not the short drop depicted. The large knot depicted was not used in Britain (although it was in America) ; a simple sliding loop was actually used, and this was positioned under the jawbone at the side of the neck, not at the back of the neck, which would quite probably not have broken the neck, leaving the person to strangle to death.

Factual error: Chief Superintendent Hilton wears the ribbons of the General Service Medal (awarded for military service in a combat zone, most commonly in Northern Ireland) and the Police Long Service and Good Conduct Medal (awarded for twenty years' service), but not the Golden Jubilee Medal (awarded to all officers with five years' service in 2002), which he would also have. When he reappears in Series 4, he is wearing the Golden Jubilee Medal, Diamond Jubilee Medal (awarded in 2012) and Police Long Service and Good Conduct Medal, which would all be correct, but no longer has the General Service Medal.
