This is the very last installment in the Olsenbanden Jr.-series.
The door Egon enter at Akershus festning (Akershus fortress) is the same door used for 'Tower of London' in Olsenbanden gir seg aldri! (1981).
Hilde Lyrån worked with Arve Opsahl, who played Egon Olsen in the original series, on the popular sit-com, Mot i brøstet (1993).
Oskar Øiestad did not return to the role of Egon Olsen for this film for some unknown reason.
