In the newspaper the mayor is shown (circa minute 39) with Orloff's ad, the ad is clearly stuck on a newspaper page. Other advertisements are partially covered by it.
The credits have several typos and mistakes: "Culb" instead of "Club"; "Deprotivo" instead of "Deportivo"; diacritics are used only sometimes with no reason ("eléctrico" with acute accent, immediately before "fotografo" without it, but both word follow the same grammatical rule in Spanish); the monster is sometimes listed as Jocántaro and sometimes as Yocantaro.
