Milos Macourek and Václav Vorlícek later used the shrinking motif again and developed it further in their mini-series Hamster im Nachthemd (1988).
Frantisek Filipovský was only 13 years older than Jirí Sovák, who played his son. They also played a father and a son in Wenn wir erstmal reich sind... (1980).
Milos Macourek and Václav Vorlícek later returned to the motif of a child trapped in an adult body and vice versa and developed it further in their series Der fliegende Ferdinand (1983), Hamster im Nachthemd (1988) and Die Rückkehr der Märchenbraut (1993).
The part of Mr. Netusil was written with Milos Kopecký in mind. However, Kopecký was busy working on Adele hat noch nicht zu Abend gegessen (1978). Juraj Herz, who eventually played the part, conceived it as a tribute to Kopecký and precisely imitated his characteristic gestures, movements and articulation.
