A Knight In Shining Armor - S1-E1
Continuity mistake: When Kitt's on fire, before getting back to the HQ, we see a shot of the main HQ screen, and towards the bottom left is a screen with a picture of Kitt and green writing reading "Fire extinguished".
Revealing mistake: Episode 15, "Faceoff": When the agent fires the hook to get to the roof of the church, it does not reach the balcony. However in a following shot you can see the agent climbing there. (00:10:05)
Continuity mistake: In the morning, Annie comes into the kitchen and says hi to her niece and nephew. Her jacket is alternately buttoned or unbuttoned. (00:39:30)
The Tale of the Pinball Wizard - S1-E13
Visible crew/equipment: When Russ is in the royal chair and it is moving on its own, right after it hits the witch you can see a crewman behind the chair pushing it.
End Game (1) - S8-E7
Revealing mistake: Boyd has a video-conversation with Linda on the phone she sent him. On top of the screen you can see how long the video will last (1 minute and 3 seconds), showing it's a pre-recorded video, not an actual live conversation.
Blood Drive - S2-E6
Character mistake: Zayday makes incorrect statements about blood types. She mentions that, since Chanel #5 is type O-, her parents must also be O-; in actuality, they could each be type A or B (genotypes AO or BO, respectively) and could also have Rh+ blood as long as they also carry the recessive Rh- allele. Zayday also says that the child of two O+ parents must be O+, but actually the child could also be O- (again, if the parents carry the Rh- allele).
Visible crew/equipment: As Joe approaches the third car with the bad guy in it, there is an unknown man, possibly a crew member, reflected in the back window where there wasn't a man before.
Continuity mistake: When Miles jumps off the ferry to swim ashore, the camera view is from the ferry: he jumps into quiet, fairly level water, yet the camera recedes from him (he jumped off the back of the boat as the camera continues moving with the boat). The angle changes and we see the wake of the boat - but it's not what he jumped into.
Revealing mistake: Hannah sits in a conference room and pulls a landline phone towards her to dial her friend, asking about the will Owen left. The phone however isn't in any way connected, hence no call could have taken place.
Continuity mistake: Kurt is still recovering from the beating he took in the previous episode with bad cuts on his forehead, checks and temple area. They are red and impossible to miss while he is in the police station. The cuts have miraculously disappeared in the next scene when he goes to visit Mona.
Factual error: About 45 minutes into the episode, the girls' car stalls because the alternator's wire has been removed to cause this. For a car to stall like this, the battery has to be heavily drained which it would wind up being. When the killer comes up to the car, he tells her to try and start the car. She does and it turns over but doesn't start. The battery would never have enough amperage to turn over the car if it didn't have enough to keep the motor running.
Continuity mistake: Jamie and Adam are shooting at Police badges to see which one would potentially stop a bullet. When they get to the third badge, it is held up to the camera. It says 'Jamie Hyneman' on the badge. The badge is then shot, and shown again to the camera. This time the engraved writing on the badge has changed to 'Adam Savage'.
Factual error: Haloclines are referred to throughout, and depicted occasionally as some sort of underwater tornadoes. Haloclines are in fact just salinity gradients, and look nothing like they do on the show.
Character mistake: A shot shows Djimon Hounsou completing his year entry on a large chalk board. The entries are 20 years apart. The third entry on the second line is 2274, the next should be 2294, but instead it records 2394. The one after corrects the sequence with 2314. Considering there is an entry only every twenty years, you would think he'd be more careful. (00:20:15)
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.
Is Lupin Burning... ?! - S1-E1
Other mistake: The logo of the evil organization, Scorpion, contains just a little misspelling. It's missing the R. (00:02:50)
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.
Revealing mistake: Mr Knight shoots Suzie Boreton - after the muzzle flashes and sounds stop the bolt of his MK14 EBR continues to move back and forth as if it's still firing. (00:30:30)
The Dark and Bloody Ground - S1-E3
Visible crew/equipment: When Rockford returns to his trailer and begins to tell Rocky about his ordeal with the semi in Arizona, just as Rockford says, "It tried to run me off a mountain," watch as the microphone pops up at the bottom, right side of the screen behind the glass bowl. (00:22:55)
