Eight films have been made in total, though in the last three films actor Gösta Ekman got tired of his character "Sickan", and was replaced by the following characters, in order; "Doctor Max Adrian Busé", "Herman Melvin" and "Sven-Ingvar 'Sivan' Jönsson".

Jönssonligans arch-enemy is Jacob Morgan Rockefeller Wall-Enberg Jr. - somewhat of a cross between a business magnate and a ruthless mob boss - who in all the films have been played by Per Grundén.

His name alludes to the real-life Swedish business magnates Anders Wall and the Wallenberg family.

The only recurring actor in all the Lilla Jönssonligan is Loa Falkman who plays Wall-Enberg Jr's father Oscar Wall-Enberg Sr. A reboot named Jönssonligan – Den perfekta stöten with new actors in the roles was released on 16 January 2015.

[3][needs update] Jönssonligan has also featured in two adventure computer games and in comics, both incarnations incited by the Swedish cartoonist Per Demervall.
