Visible crew/equipment: When Ned walks upstairs to check on the lady before the bad guy gets killed, behind him is a circular window. A reflecting light can be seen in the window along with what looks to be a boom microphone.
The Agent Of Year Zero - S4-E14
Revealing mistake: During the scene when Mr. Lyle is talking to the General (butcher character), his glove that he wears on his hand is removed to make a point about his thumb having been cut off. In the next shot, we see Mr. Lyle walking around the desk and putting his glove back on, and you can see his thumb folded under his hand as if the actor was trying to hide it and did not realize it could been seen from the camera angle.
Plot hole: Laura successfully knocks out both bad guys, steals their van and crashes through the warehouse doors. The van doesn't stall, but inexplicably, she stops it, gets out and runs away on foot, even though the baddies are coming to and coming after her. Not the option you'd expect a kidnap victim to choose: most people would floor it and keep on driving. (00:23:40)
Continuity mistake: Just before the robbery, Jake throws some water bottles and a flashlight over a small mound into the bushes, to hide them from the thieves. But when Mimi later picks them up, they are much closer to the truck, and on the other side of the mound. In fact, the bottles and flashlight would have been in plain sight for the robbers where she picks them up.
Factual error: The bad guys are supposedly auctioning off the stolen Mona Lisa. But they and their prospective buyers aren't very art savvy. The painting is more than twice the size of Da Vinci's actual masterpiece. (00:44:50)
Continuity mistake: When Anne and Evert are driving toward the Norwegian/Swedish border, Anne pulls back the rug in the back of the sled, and discovers the dead Bjørn. He is then flat on his back, staring upwards. Moments later, when the Swedish border guards pull back the rug to look at the corpse, he is face down. No one touched him, and the sled did not bump enough to roll the body completely over.
The Sins of the Father - S4-E9
Factual error: A character is revealed as having been hypnotised into committing murder against their will. This is not possible. (00:05:20)
Rumpole and the Fascist Beast - S2-E4
Visible crew/equipment: While Rumpole's wife prepares the canned soup in the kitchen, several equipment shadows are moving on the wall at the top of the screen. (00:06:40)
Continuity mistake: When the lab equipment shorts out after the earthquake, the unconscious Major Brothers is lying with his head propped up against the wall. But when Hamilton reaches him in the next shot, he's suddenly lying flat and is nowhere near the wall. (00:21:45)
Continuity mistake: When Max is phoning the Chief to let him know the mission's been accomplished, he takes the oars out of the oarlocks before opening his shoephone. The oars change from being out of the oarlocks in the closeups to still being in the water in the long shots for the rest of the episode. (00:23:50 - 00:24:30)
Continuity mistake: When Brian and Gerry are chasing Kelly, Kelly's jacket is only zipped up at the bottom at the start of the chase, but when the camera angle changes it is zipped all the way up for the rest of the chase.
Coming Home - S1-E3
Factual error: At the convalescent home, Dr. Conner asks if a lector has been to the home to give communion. Later, he describes a lector as a person who gives communion at church or to the homebound. A Eucharistic Minister or Extraordinary Minister of Holy Communion gives communion in the Catholic Church.
Factual error: Radio talk show host David Campbell works at "WRQE 480 AM." There is no such frequency. The AM radio dial begins at 530.
Revealing mistake: When Harrow and Nicholls are in what is supposed to be Queensland Police Headquarters, a window is visible with logos for Radio National and Triple J behind them. This shows that the scene was recorded at the offices of the Australian Broadcasting Corporation. (00:31:04)
In Too Deep - S5-E8
Plot hole: Carter is apparently just learning about Feynman's Day, which Allison explains as "Eureka's version of April Fool's Day." It's highly improbable that Carter could have lived in Eureka for five years and still be oblivious of this, especially given all of the hijinks that happen.
Episode #1.1 - S1-E1
Factual error: This is set in 1933. When the killer comes back to his lodgings in episode 1, Lily on the stairs is humming "Somewhere over the rainbow", which was written for The Wizard of Oz in 1939. She also happens to wear bright red shoes, which feels like yet another Wizard of Oz reference. Interesting enough, the subtitles say that she is humming a different song, "Night and day" which she openly sings throughout the series and was already a hit in 1932. (00:44:10)
Visible crew/equipment: In the rec hall, when Kensi feigns sickness while posing as a cadet the gunman jumps off the stage, and as Kensi bends over the small rectangular bulge of her mic pack can be seen at her back. (00:30:25)
Factual error: The Secretary of the Air Force enters a room. A captain not in uniform salutes him. You do not salute out of uniform, and you do not salute civilians. You stand at attention. (00:09:20)
Character mistake: When Ginnifer Goodwin leaves the supermarket to go the parking garage, the green sign says 1 hour parking Customer's Only. It should say Customers Only, without the apostrophe.
See One. Do One. Teach One - S1-E1
Revealing mistake: When they find victim #2 in the woods covered in leaves, in almost every shot of her you can see her breathing - leaves moving up and down. In the closeup of her neck, you can see her swallow.
