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)
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)
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)
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)
