No. 6 attaches a note to a pigeon. When he writes it, he uses black ink, but when it is retrieved for No. 2, it is written in blue ink.
As Number 6 views the window of the General Store, the blue and yellow signs in the window switch locations between close-up and distant scenes.
When No 6 walks away from the band, after requesting the "Farandole" from "L'Arlesienne", three umbrellas can be seen amongst the audience, which were not there, when he was walking towards the bandstand.
While the fight is occurring in #6's quarters the phonograph is seen from above and the tonearm is seen returning to rest but the music is still playing. But moments later the arm is seen back in the playing position and the music was never interrupted.
Number Six takes a cuckoo clock to Number Two's residence. At one point, there's a close-up of the clock and it indicates it's half-past eleven. Number Six starts walking up some steps, and there's another look at the clock. The hands now indicate it's noon when only roughly ten seconds have passed.
In this episode, Number Six is depicted as owning a phonograph and the Village store sells records, indicating that the Village residents can choose whether to listen to music or not, and what music to listen to. In previous episodes, all the rooms in the Village were provided with black radios that broadcast music and announcements to the residents, and they had no outside controls so they could not be shut off.
No 6's Spanish is wrong. It should not be "Y mas mal in Aldea que se suena" but "Hay más mal en la aldegüela que se suena", which is what appears in Don Quixote.
The girl at the kiosk charges No 6 for a nine word advert, when in fact he says eight.
