Continuity mistake: One moment Frankie takes out two shot glasses and a bottle and starts to pour. She pours maybe one-fourth of one glass. The very next shot, both glasses are filled. (00:03:35)
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.
Chapter Four: The Moveable Feast - S1-E4
Audio problem: When Father Keane is speaking with Mother Bernadette outside, when Mother Bernadette says "The gift doesn't reside in you or me", and "Where you coerce and compel, we use compassion, forgiveness, and patience", her lips do not match what she is saying.
Other mistake: The shopkeeper hands Danny a Beretta 92fs/M9 handgun with a detached suppressor. To mount a suppressor to the muzzle end of the handgun the barrel needs to be threaded, and this one isn't. Sometimes barrels are threaded and when no suppressor is attached they are protected by a thread barrel cap to protect the threads from dings and bumps. There is no thread cap here either. (00:22:35)
Factual error: A scene in a photographic darkroom shows Michael Gambon developing a colour print in a dish under safe lights. Not possible. Colour printing must be carried out in pitch dark usually inside a light tight print processor, as colour photographic paper is sensitive to all wavelengths of visible light.
Audio problem: They went to an investigator to let him listen to the audio. The audio with the woman screaming and the gasp, the gasp was Zak, not another apparition.
Episode #2.8 - S2-E8
Factual error: In the opening seconds of the intro the BTK killer is following a woman home in his work van. Both the woman and BTK have license plates on the front of their vehicles. Kansas does not use front license plates. (Also, BTK's van shows the county abbreviation on the plate as WY - Wyandotte County - where Kansas City, KS is located nearly 200 miles away. The county tag abbreviation should be SG for Sedgwick County).
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.
The Family - S1-E6
Character mistake: The pharmacist says she's sorry, but they don't have the drug Lamotrigine in stock, so would the generic be okay?Lamotrigine is already the generic form of the drug Lamictal. (00:28:23)
Plot hole: After Grant finishes her video confession, Latif puts the video recorder in his cargo pant pocket. A few scenes later, he's blown up without ever having taken the video camera out of his pocket. He was at the epicenter of the explosion and he and his clothes were very much on fire, which should have completely destroyed the video camera and its recording.
The M.O.D.O.K. That Time Forgot! - S1-E2
Character mistake: M.O.D.O.K. refers to Hoobastank as "the Beatles of the late 90's." Hoobastank only released one album in the 90's, and they didn't become popular until after they released their second album in 2001.
Continuity mistake: When Gary is at the end of the table talking about Golf, he's actually seated in front of the table as seen by how he grabs his cup in front of him. In the very next shot, he's no longer sitting in front of the table and is sitting past it.
Winning Through Intimidation - S1-E15
Continuity mistake: Panik's Metal Guardian can be seen on the field several minutes before he actually plays it. (00:10:30 - 00:13:00)
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.
Continuity mistake: When Nick's mom tells him to show Gypsy around she takes the cigarette away from her lips. A shot later it's back in.
Episode One - S1-E1
Factual error: In the fairground chase the characters jump over some Heras fencing that wasn't invented until the next decade.
Factual error: The Royal Navy sailors are shown with just 'HMS' on their cap tallies. This was only seen in the Second World War for security reasons. In peacetime, the tally bears the name of the ship or shore establishment to which the rating is assigned.
An Affair to Dismember - S1-E8
Audio problem: When Lexy walks up to Chucky behind the movie screen, you can see Chucky's mouth moving like he's speaking, but there's no audible dialogue. (It's shortly before he says "See for yourself.") Seems they decided to change the dialogue in post-production and cut out some of it.
Factual error: Jake and Miyamoto go to an establishment where there are girls dancing on stage. The girls are first dancing to "Motivation" by Kelly Rowland, released in 2011, and "Aly Walk With Me" by The Raveonettes, released in 2007. But, this scene takes place in 1999.
Factual error: Possibly a mistake from the novel on which the series is based, but although he later became Bishop of Hereford, St Thomas Cantilupe wasn't baptised in Herefordshire. He came from Buckinghamshire.
