Episode #1.7 - S1-E7
Revealing mistake: When the guitarist punches the bass player in the face you can see him miss. (00:50:02)
Revealing mistake: When they break the door to the nurses room down because it's locked, you can see the lock is retracted so there was no need to break the door down. (00:05:10)
Revealing mistake: The doctor closes the blinds on the ward and picks his phone up and makes a call. However, you can see the screen never comes on so how could he choose a contact to ring?
Revealing mistake: The photo from the high school years of Edwina and the candidate is a photoshop Frankenstein where you can see the face of the actress pasted on someone else's head. (00:24:50)
Revealing mistake: Humphrey and the team receive the decisive last clue from Saint Marie; on the Scotland Yard PC, in the inbox there are tons of emails marked as 'today' that come from places like the Guadeloupe lab and instead days old. (00:34:35)
Revealing mistake: The photo found by JP in the newspaper archive is photoshopped so badly that you can actually see the line where Julian Wadham's face has been pasted onto the sailor's head. (00:44:55)
Revealing mistake: Dwayne turns the volume of the computer in DI Jack Mooney's office; when we start hear him, the volume has gone up just a few notches, but it's already just as loud in the end as it is when Dwayne finishes to set it. (00:29:10)
The Secret of the Flame Tree - S6-E2
Revealing mistake: Florence shows to her boss a copy of the birth certificate of Lizzie Baptiste. It is signed "Overseas British Territory of Saint Marie", dates back to 1954 with a photostatic copy of the original typewritten entry, and her school certificate is also written in English. Saint Marie though, according to its fictional history, was part of France at the time, having been a British territory only for 30 years before Season 1 (set in 2011). (00:25:40)
The Secret of the Flame Tree - S6-E2
Revealing mistake: The sepia-toned memento that Florence spies on the wall of Chez Lulu is supposedly from 1969, certainly a photoshop horror from 2017, with the faces of the two siblings ghastly superimposed. (00:24:25)
The Secret of the Flame Tree - S6-E2
Revealing mistake: At Catherine's, Dwayne is reading a copy of The Saint Marie Times, announcing the new candidate for Mayor. The text used in the prop though, is obviously the same used in the prop for the first episode of the season - the article is all about Commissioner Patterson. (00:26:20)
Revealing mistake: When Dwayne holds the copy of the local newspaper with his goat comment making the headline, the text of the article repeats itself; you can see aligned in both columns the name of the commissioner accompanied by "pictured right." (00:23:15)
Revealing mistake: Dwayne supposedly swapped the rum with Humphrey, but if you pay attention during the time when JP hands them the glasses, it simply does not happen. (00:26:00)
Revealing mistake: Florence and Humphrey are reading the article about the young Dexter Allen from the Hackney Gazette. Behind the article, Florence has her mail open. Amazingly enough, the names of the people she received mail from (Joshua, David, Faye, a Customer service) are the same ones as the victims in She Was Murdered Twice, season 4 episode 7 when one of the suspects opened it from a public computer. (00:30:45)
Revealing mistake: While they are checking out Matt Holt's discount Facebook page (Face-spaces dot com) on the computer, behind the browser window there's an open file with a fingerprint, and like in another episode of this series, it's a fingerprint not related at all to this case, but one from three years earlier, the episode of season 3 "Ye of Little Faith", this time from the victim of that case Natasha Thiebert. (00:26:30)
Revealing mistake: When Humphrey checks out of the mail from the dating website at the end of the episode, behind the window of the mail client, there's a fingerprint file with the name "Adam Frost" and a 2014 sampling date; it's a file recycled from two seasons before, 3-4. (00:49:55)
Episode #4.5 - S4-E5
Revealing mistake: Florence prints the first page from the Saint Marie newspaper, from a generic "Thursday 12th"; the whole first page is taken by the news of the fire destroying the recording studio...but half of the article talks about "the world's largest message in a bottle", instead. (00:16:25)
Revealing mistake: In most episodes of the season, the computers at the station lack the power cable. It might make sense in the very first episode when it is mentioned that they aren't in a working state, but under Richard's guidance they routinely use it afterwards. For instance in episode 3 Camille during Tom Hilton's interview, Camille is looking at an active computer screen despite it being unplugged.
Episode #4.2 - S4-E2
Revealing mistake: Camille puts the name of the victim and "Watergate" as search terms, and manages to find the relevant news item from the past. The URL of the website though is just the one of the (fictitious) homepage (watergatenews.org), and not of a specific article. Moreover, the article is half relevant info, and half generic guide about surfing with a brisk cut from one to the other. (00:21:50)
Episode #3.7 - S3-E7
Revealing mistake: Dwayne finds a newspaper which hilariously happens to have a perfect close-up photo of one of the suspects out of the thousands of protesters, right on the first page. Couple of problems with it; first, the text is just 2 paragraphs copy/pasted all over, and second, more blatant; the caption of the photo says "Valerie Clayton", but Dwayne just called her "Valerie Pellow." (00:33:00)
Episode #3.7 - S3-E7
Revealing mistake: Goodman and Bordey are interviewing Terrance Jackson after the revelation involving Rosie. During the scene, in most shots despite the storm that supposedly is happening, the leaves outside are subjected to a gentle breeze if at all. (00:26:00)
Answer: Most likely they had only tropical exotic drinks, he wanted an old fashioned English beer.
