Even though a spin-off of the popular Olsenbanden series, this is a remake of Lilla Jönssonligan på styva linan (1997).
Robert Opsahl and Sindre Tveiten who plays Kjell and Johnny in this movie, also played Kjell and Johnny in Olsenbanden Jr på Cirkus at Oslo Nye Teater in 2004, two years before the movie was released.
The roles of Egon, Benny, Kjell, Harry, Valborg, Ingrid, Biffen, Knut, Johnny and Herman were recast due to the actors from the previous movies in the series got to old to play their roles.
