Episode #1.2 - S1-E2
Factual error: The settlers prepare to burn Verity at the stake as a witch. Witches were never burned in England or her colonies; they were hanged.
Episode #1.3 - S1-E3
Audio problem: Elaine refers to someone's "ChatsApp" account, but her lip movements show she is actually saying "WhatsApp." (00:13:55)
Other mistake: You don't have to look further than the name; the title of the series is "Knight's and Magic" instead of "Knights and Magic".
Continuity mistake: The way "Jack Griffin" is written on the board changes in various shots.
Factual error: ACC Pat Gallan wears the ribbon of the Queen Elizabeth II Diamond Jubilee Medal. The medal was issued in 2012. Her medals would be correct for 2017 when the series was made, but not 2007 when it is set.
Other mistake: There is a countdown on the movie screen. It is then reflected in Dusty's glasses. But the numbers are not reversed in the glasses. (00:41:00)
Continuity mistake: When Josh is asking his dad if the cops were hot, from the side he's leaning forwards with both elbows on his knees, then from the front he's more upright with one hand on his knee, arm bent out to the side. (00:09:45)
Visible crew/equipment: When Adrian is getting something from the snack machine, the cameraman can be seen in the snack machine's reflection. (00:26:30)
Continuity mistake: When Evan is out with Doug it is day time. Evan proceeds to get out his cell phone to text Casey. Then we see Casey and it's nighttime. (00:11:50)
Continuity mistake: When Ben is in the prison cell and one guy asks him if the other prisoner can be trusted, Ben folds his arms. In the next shot, Ben folds his arms again.
Factual error: In the last 2 episodes of series 2, when anyone uses a phone box it has the the BT Piper logo on the outside, which wasn't introduced until 1991 - six years after the series is set.
Factual error: Every Time the Shadow Raiders deploy to Somalia, they use a Blackhawk nicknamed "Adele" for their missions. I can understand the helos being transported via fixed-wing aircraft, but on their last mission they leave Georgia, and reach Somalia the same day, flying in the Blackhawks. It would take them some 15-20 hours not including fuel stops. Yet the mission is completed in the time it takes to find a bomb in downtown Atlanta.
Episode #1.4 - S1-E4
Factual error: The soldier who shoots Yusra's father is listed on the credits as "Royal Scotch Guard." There is no such thing. There are two regiments: the Scots Guards and the Royal Scots. The soldier was actually a member of the latter, as correctly described in the dialogue.
Episode #1.5 - S1-E5
Factual error: The senior police officer's name tag reads "Assistant Commissioner" but he wears the rank insignia of a Deputy Assistant Commissioner.
Episode #4.9 - S4-E9
Factual error: Renate escapes from the prison in a Morris Ten Four, with the badge visible on the bonnet. However, this designation was not introduced until 1935 and the episode is set in 1931.
Continuity mistake: The piece of junk that Rey feeds to the Nightwatcher worm appears between her and BB-8 with the pointed end of it facing away from BB-8 towards Rey, with the round end pointed out. When she bends down to pick the junk up, in the close up the pointed end is now facing outwards from between her and the droid with the round end towards BB-8. (00:02:10)
Other mistake: The sign behind James Franco on the mirror behind the bar says, "Dinner Service Until 10pm". It's a modern paper printout and also a modern font, from a personal computer / printer which nobody would have at that time. (00:07:00 - 00:08:00)
Boundaries - S4-E3
Continuity mistake: Alex and his mom are talking with Grandma about masturbation. Alex is in his school uniform shirt but for one shot he has a hoodie on, then in the next shot it's gone.
Continuity mistake: When Andi tells Buffy and Cyrus about the one date with Walker, she gives Cyrus the clear cup with a red design and Buffy gets the green cup, but when Buffy insists that she's the sassy friend those two cups switch between shots, then the cups switch back again. (00:13:50)
Factual error: When Detective Inspector Sara Lunt's photograph in uniform is shown on the TV news she is wearing a double row of silver lace below her hat badge. Only chief constables wear this insignia, well above the rank of inspector.
