Creator Backlash: André Franquin has admitted that he didn't like one of his early strips where Gaston invents a bird call whistle that attracts a weird bird that doesn't exist in real life, since he felt like fictional creatures didn't fit the comic's spirit.NoteEven though Franquin did enjoy drawing weird grotesque monsters outside of the Gaston comics.
Creator Breakdown: Bertand Labévue started as a generic lunatic guy and became depressive after Franquin dealt with depressions.
Died During Production: The series was discontinued after the death of Franquin. This is shown in a somewhat chilling way with the last sketch (Number 913), which Franquin had started working on. His death had come very sudden, as all but two panels have been sketched with pencil and a third of these had been inked. You almost feel him starting to work on it, never suspecting it would stay unfinished.
Reality Subtext: The character Bertrand Labévue gets hit by depression because Franquin himself had it.
Radio Enfer: After Carl makes a blunder by making fun of a renowned talent agent named Ronnie Angello without knowing who he was beforehand, Maria introduces Carl to Angello by calling the former "Gaston Lagaffe".
The Comic sequel by Delaf:
Promoted Fanboy: Delaf was a big fan of the Gaston comic and he did homage fancomics where he was very faithful to the style. Enough so that he has become its new official artist.
Sequel Gap: Le Retour de Lagaffe was released in 2023, 27 years after the last officially published Gaston album back when Franquin was still alive (in 1996).
Descended Creator: Pierre-François Martin-Laval is both the movie's director and Prunelle's actor.
Disowned Adaptation: André Franquin's daughter Isabelle had nothing nice to say about the movie before its release, calling it a disaster. In particular, she vetoed the movie script's first draft (see What Could Have Been below), but having no control over the franchise, she was powerless to stop the production entirely.
Fake Nationality: The country the film is set in isn't specified, but going by the original comics (since some clearly Belgian names have been kept in), the characters are Belgians. All the actors are French, meanwhile.
Missing Episode: The entirety of the 1989 Merci Gaston! TV series is unavailable. There are no clips to be found anywhere, and only a few photographs had been published in magazines. For more information, see here.
