First appearance of Dynamitt-Harry (Harald Heide-Steen Jr.). The character appeared in two movies in the Danish series, but due to Harald Heide-Steen Jr.'s portrayal and popularity the character went on to make more appearances in future movies.
In this movie, Pål Johannessen's character 'Basse' is named 'Birger', the same as the older brother in Olsen-banden (1969). This is change back for future sequels.
Only 'Olsenbanden' movie where Egon (Arve Opsahl) and Valborg (Aud Schønemann) doesn't share any screen time.
The first, and only time, Egon is seen doing honest work. Benny and Kjell would go on to get steady jobs in Olsen-banden og Dynamitt-Harry går amok (1973).
The only movie where the plot doesn't evolve around Egon's plan.
