Cameo: Antonio Mingote. The author of the comics that this movie is based on, appears as a bystander who will not vote for Gundisalvo.
In this movie, Gundisalvo uses a machine for static cycling so as to improve his shape. This is a reference to one of the comics, where Gundisalvo appears on a static bicycle with the slogan "moving towards the future".
Based on Antonio Mingote's comic one-panel jokes published in newspapers. Plotless and without continuity, those panels featured contradictory actions in just one image (e.g. a panel where a very polluting truck proudly shows an poster of Gundisalvo against pollution)
