Deliberate mistake: When the people come into the club looking for money off the owner a fight breaks out between the Krays and the people the Krays stick a sword through the gang leaders hand. But it quite obviously goes through the gap in his fingers. (00:35:10)
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)
Deliberate mistake: While the events depicted in the film take place over nearly a decade and a half, the characters are not shown as having aged at all throughout the film, apart from Mike Lazaridis. In fact, characters are seen wearing the same clothes and the same ties between scenes that are set years apart.
Deliberate mistake: Although much of Auto Focus revolves around the 1960s hit television series "Hogan's Heroes," the producers of this independent film could not work out a licensing agreement with CBS regarding the famous "Hogan's Heroes" theme music. As a result, the familiar "Hogan's Heroes" theme music is entirely absent from Auto Focus, replaced with contrived theme music that isn't even remotely similar to the original.
Deliberate mistake: The mechanic points out the overhead installation of the indicator compass. He says "Want to see where I put the compass? It's the best place I could find for it." The installation site was planned, not improvised. In order to read the compass in a mirror the compass was specially ordered from the manufacturer with the numbers reversed so it could only be read in a mirror. This mistake was intentional in order to claim a mirror was needed from a bit character.
