Maria Gladkowska's debut.
The daytime chase scene was filmed on "Kerepesi út", without route security or police escort. A few cars were only introduced, mostly those that the main character drove into, the exception being the collision with Zaporozsec in the "Örs vezér tere". The filmmakers paid for the damage, and it was settled.
Simon's parents are watching the 1934 Meseautó when he visits them, the main character of which is Zita Perczel, and she can be seen in that scene with Gyula Kabos.
György Cserhalmi received HUF 20,000 for the film, just twice as much as is stolen from the character he plays in the film.
At the time, the film was considered so dark that in several socialist countries it was only allowed to be screened without certain scenes (especially the very end).
