Deliberate mistake: At least twice the protagonist uses the bus n*38 who brings him in and out of his new neighbourhood and that has on its side an ad banner. The banner pays homage to the movie Roger Spottiswoode directed before this one (in 2014, so it'd be an anachronism given this movie's events), but it stands out for not being done properly. The first time we see it it does not have proper 'credits', copywrite, tagline, to the point that it's not possible to understand what does it advertise, the second time it does have some writing. The title quoted is also wrong, since it's written as "The Midnight Sun", while the title before re-release was "Midnight Sun." (00:11:40 - 00:38:30)
Factual error: At the book signing, the store features books who are not from the correct timeframe but from the time when the movie was shot in late 2015. Examples include a book of baby names with a big 2016 on the cover, on a shelf right when Betty appears, or "The Complete Discworld Atlas" by Terry Pratchett, between Anthony Head and Beth Goddard in their close-up during James' speech. (01:34:35)
Factual error: James is having the preliminary chat with the book publishers. They are discussing in a room with several promo posters ("Alice and the Fly", "Solitude Creek") of books that came out in 2015, well past the date the movie itself reveals later. (01:30:20)
Continuity mistake: James after talking to the pushers outside his house steps in, and behind him we see Bob curled by the window. In the following close-up the cat is turned in a different direction. (01:21:00)
Deliberate mistake: Some odd legal matter must be involved here; when we see the two ladies look at the viral video, one tells the other to look at the "Youtube" sensation with over a million views, but the website shown is not Youtube but an obvious knockoff version. (01:19:30)
Continuity mistake: When Bob runs away during the incident with the pushy lady that wants to buy him off James, the cat is wearing his leash in some shots, and isn't in others. (01:16:50)
Other mistake: After a month of suspension, James can finally sell again The Big Issue. The issue he carries in the street though, is issue 1174, from early October 2015. Besides the anachronism, the first issue he was selling, well over a month before, was number 1175. (01:16:00)
Factual error: James has a meltdown right after New Year's Eve, and to try and get his life back he turns to the good fellas at "The Big Issue", magazine that famously offers an opportunity to the homeless. The issue they give him to sell has Tom Jones on the cover and the title, appropriate to the theme, "What's new, Pussycat?" Problem is, not only it's an issue from 2015 (posterior to the events of the movie) but it's also from October. The two posters we see in the office are covers from early 2012, so those do instead fit perfectly in the timeline. (01:07:00)
Continuity mistake: James is eating the non-Christmas lunch with Betty; he says "I'm tofu, and I'm inedible", and she laughs. In these two shots, she has different food on her fork. (00:55:30)
Continuity mistake: Throughout the conversation with Betty after Baz's OD, Ruta Gedmintas' hands/fingers change position on the cup between shots. (00:53:00)
Character mistake: It happens in real life too, but when Betty makes the "I'm a level 4 vegan; I don't eat anything that casts a shadow" joke, she misquotes The Simpsons' episode where the quote originated. That'd be level 5. (00:48:40)
Continuity mistake: At the end of James' performance of Silent Night, the cat lady hands him a can of food. The can turns around in his hand at the cut. (00:48:00)
Continuity mistake: The evening that follows the first successful performance, James opens a can of food for Bob. He puts the can to his left, but in the next shot the can is on the opposite side of the table, to Bob's right. (00:45:30)
Continuity mistake: During the first performance with the cat, singing "Satellite moments", a man in a brown sleeveless jacket and sporting a beard approaches James holding a shopping bag in his right hand. In the close-up of the cat he is bending to deposit the coins he had in hand, but his bag moved to the left hand. (00:42:30)
Factual error: James makes a leashed Bob hop on his back. When he announces "This is Covent Garden", to the right there's a new store getting set up; it's the famous international stationery brand Kikki K, which opened for the first time in England in late 2015. The movie is supposed to happen years before. (00:41:00)
Continuity mistake: When James is on the bus with Bob, he is holding him with his hand positioned in front or behind Bob's front leg, depending on the shot. (00:39:00)
Continuity mistake: Inside the vet's waiting room, James gets ticket 62. Not too bad considering in close-up the digital display shows they are serving patient 57. But after half an hour passed, in the background before he says "Bob, look, it's the month of the cat" the counter is at 51. (00:26:20)
Factual error: When James spots his dad (Anthony Head) and stops him in the middle of the street, they have a brief chat in front of a big marquee advertising "Charlie And The Chocolate Factory - The Musical." First represented in 2013, with the movie ending in 2012. (00:20:50)
Factual error: James is playing his guitar outside a station. Before the frontal shot that identifies it as Covent Garden, there's a street poster for the musical version of "Matilda." The play was already in existence in the movie timeframe, but the poster is in its "Believe the hype" version that is post 2013. The movie ends in 2012. (00:19:55)
Factual error: In the montage showing James busking after committing to the program, he picks up his guitar when it gets dark and tries to find shelter. On the side of a London bus, you can spot the ad for "The Hunger Games; Mockingjay - Part 2", a movie that came out in 2015. The happy ending of this movie takes place in 2012. (00:09:55)
