Actor-Shared Background: Besides being Trino's Author Avatar, El Santos shares many details with him, along them being soccer fans, especially from Club Atlas, being from Jalisco (especifically from Ajijic, near the Chapala Lake, when Trino lives) and being both foul-mouthed. The only trait Trino does not share with Santos is being a Jerkass, since Trino is famous for being a pretty nice guy in Real Life.
Alan Smithee: A very weird case: Rather than being the voice actors the ones using alias for hiding their identities, it's the animation studio the one using an alias instead: The movie is animated by Anima Studio, under the Peyote Films name (the ones who worked in the animated adaptation of El Chavo del ocho and the Top Cat's recent animated movie) and the reason for doing that (according with both Trino and Jis) is because they don't want to have any problems with any potential clients if they find out they worked in such a movie like this.
Some stuff from the earlier issues from comic book were different from the latter ones and also from the movie:
El Santos was originally taller and fatter and less prone to use profanity than his latter incarnations, not to mention the humor was more of the normal (albeit a bit wierdier) type.
Valdivia was a Jerkass like everyone else earlier.
Hey, It's That Voice!: The original voice acting for the animated movie includes many Mexican movie actors, including some world-famous names like director Guillermo Del Toro (he voices Gamborino Ponx, a talking hemorrhoid.) and even Cheech Marin!note And being the first time he plays a role in a foreign film in Spanish, despise not being able to speak that language.
Another interesting tidbit is, unlike many other Mexican animated films, this one does not use professional dubbing voice actors (the ones who dubs foreign media) and relies entirely in famous actors instead. This is possibly was intentional, since the movie is geared towards adult audiences and, since in Mexico, the Animation Age Ghetto trope is still strong there, using famous actors rather than dubbing actors gives more credibility to the movie and avoids being tagged as a kiddie movie, not to mention that many Mexican dubbing VA normally refuses to work in stuff that uses too many profanity and excessive Toilet Humor.
Troubled Production: Trino's idea for the movie hails from the year 2000, but due to technical and budget problems, the film didn't came out until 2012.
