Caleidoscope - S2-E4
Character mistake: The chess set in Dr. Pierce's home office is set up incorrectly. When the men are set up properly, each player has a light colored square in the right-hand corner. The board as it appears in the show is set up so that the light-colored square is in each player's left-hand corner. This "beginner" mistake puts the king and queen in the wrong positions.
Other mistake: When we first see Gordon aboard his jet, the shot of the jet from the outside is a flipped shot. Note the lettering on the right engine.
Character mistake: Ryan tells Jack that Darius turned into a werewolf right in front of his and Micki's eyes. Ryan and Micki never witnessed Darius' transformation into a werewolf at all.
Revealing mistake: In brother Justin's padded cell, the far wall is obviously a painted backdrop. It even flutters when the orderly and doctor walk in! The only solid part is a couple of feet at the end, that Justin leans up against.
Factual error: A plastic bag of items is found under the footboard. Plastic bags weren't invented in 1969. They first appeared in public in 1979.
Continuity mistake: A whimpering housemaid rushes down the stairway, frightened by an intruder on the second floor. Doctor Watson gallantly charges upstairs to investigate, plunging his left hand into the right side of his jacket to retrieve his trusty Webley revolver as he advances on the camera. However, the shot immediately cuts to Watson withdrawing the revolver with his right hand from the left side of his jacket. (00:29:55)
Factual error: The chopper's main rotors are at a speed enough to cause rotor wash, but the men's coats or hair don't move at all, when they should have been buffeted around.
Continuity mistake: At breakfast the apple being cut for Camille as she poses a question to Adora is suddenly on her plate as the scene cuts to Adora's immediate reaction. (00:05:07)
Episode #1.1 - S1-E1
Continuity mistake: The characters are looking at the Ten Little Soldiers. When one of them (playing the role of Blore) is banging on the glass, you can see the hands of the mystery writer ("Lombard") leaning against the base. He's leaning on the top of the display case in the next shot. (00:22:10)
Episode #3.5 - S3-E6
Continuity mistake: Sidney is attending a pre-wedding dance in the camp he is visiting wearing a light colored shirt. When he leaves the dance floor to chat with other attendees, he is now wearing a green sweater over his shirt.
Factual error: The British Army soldiers are not wearing British Army uniforms or carrying British Army weapons and some of them have beards, which are not permitted to British Army soldiers.
Continuity mistake: When Mary talks to Bobby D at the crime scene, her hair moves back and forth over her left shoulder between shots throughout their conversation.
Family Day - S2-E5
Continuity mistake: When Harry first picks up a water balloon and throws it, his hands are now empty. In the next shot, he has a blue water balloon in his hand. When he throws that one, you see it's a pink balloon being thrown.
Factual error: The Commissioner of the Metropolitan Police has red fabric within the crowns on his rank insignia. This would be correct for most British police forces, but the Metropolitan Police uses blue fabric instead.
Die Glocke - S4-E6
Other mistake: When Jones is trying to convince Herr Waesch that she's the owner of the estate where his gala is being held, subtitles of his reply read "I personally procured this home. It's owners were French." The contraction "it's" should be the possessive "its."
Polly Wants a Treasure - S1-E8
Continuity mistake: In the scene where Baloo and Kit walk through the Sea Duck's cargo area to try and find who they think is a stowaway, Baloo lifts a crate of fragile crystal glasses over his head. The crate rotates between shots, judging by its red "Fragile" stamp.
Revealing mistake: As Sgt. Cain and Chief Lain stand by Marjorie's dead body lying on the hotel bed, discussing her death from an overdose, you can see her stomach rise and fall slightly, though she's supposed to be dead. (00:18:00 - 00:20:00)
Other mistake: Danny Stevens, an undercover police officer, is killed. The police agree to investigate the murder of his undercover persona, Steve Daniels, thus allowing the investigation of his death without compromising their ongoing investigation into the activities of a drug kingpin. The officer investigating the murder visits the kingpin to ask about Steve's murder. She shows him a photo of the murdered man, but the name across the bottom is Danny Stevens - the policeman's real name.
Continuity mistake: As Dave is leaning over the edge of the air boat with Rose behind him, he pulls a chunk of metal out of the water and places it on the edge of the boat on his left side. When he gets up from his lying position moments later, the metal is gone. Moments later again, with an overhead shot of the boat, we see what appears to be that piece of metal positioned at what would have been his right side, not his left. This is also where we see him step over the seat (twice!) in subsequent camera angles. (00:30:00)
Continuity mistake: Myron enters his own office after bailing the Simons out, and tells them to get out. Rick, sitting on his chair, lowers the hand with a cigar, but in the reverse shot Gerald McRaney is still smoking it, it's right in his mouth. (00:19:00)
