In the background at the hotel, there is a poster advertising for "World star Michelle Malene". The woman in the poster is Ellen Waaler, costume designer on several 'Olsenbanden' films. She also played 'Gry' in Olsenbanden for full musikk (1976).
Instead of shooting new scenes, some of the scenes are reused from the original Danish film Olsen Bandens flugt over Plankeværket, of which this film is a remake.
In a scene, Rolv Wesenlund is flirting with Aud Schønemann. The two of them are best known for playing son and mother in Fleksnes fataliteter (1972).
When Egon presents his life insurance to Bang-Johansen so he won't be knocked out by Biffen, Egon is looking directly into the camera, breaking the 4th wall--a clever joke since Egon has been knocked out several times in the past. Seconds later he does it again when he knows it will happen again.
When Biffen places Egon's bowler back on his head he places it crooked. In the Danish movie series, Egon always wears his bowler hat crooked.
