This, as most of the older Jönssonligan films, is based on the Danish films about Olsen-banden.
First adaption of one of the original Danish Olsen-banden films. Somewhat ironically, it is based on the sixth film, Der (voraussichtlich) letzte Streich der Olsenbande (1974), which was intended as the last one when it was made.
Was seen by over 900 000 people in the cinema in Sweden, which would be almost and eighth of the Swedish population at the time.
