Hurvinek cannot go to a circus because he injured himself when sliding down the stair rail. He daydreams that he is an acrobat riding a scooter and an animal-trainer taming beasts. (MUBI)

An animated short film that explains in a pedagogical way how the radio transmission works. Created by Czech filmmakers it was commissioned by Argentina Schools. The film tells the story of Curious, an extraterrestrial child that reaches the planet earth attracted by the sound waves. There he meets the Queen of Waves, an ethereal figure who teaches her step by step the process by which sound is captured, amplified, modulated and transformed into electromagnetic vibrations to be transmitted by a radial antenna.

Spejbl craves a film career. He thus posts a newspaper ad, offering himself as an actor. As soon as he receives a response, he sends his son Hurvínek to the agent instead of himself. Hurvínek fears that his father is again looking for a wife. He is not as representative as Spejbl would wish, and he puts the agent off. Spejbl is first angry with his son, but then hears on the radio that the agent in question was an experienced swindler, and is glad that Hurvínek in fact saved him. The Bulletin of the Czech Ministry of Interior lists the film in the section “For adults only. Forbidden for children and adolescents under the age of sixteen (comedies)”.
