ABBA members Benny Andersson and Björn Ulvaeus composed the film's theme song, which the Swedish band Gemini performed.

The film was a co-production between companies in Sweden, Norway, and the Soviet Union.

The budget was estimated at 50 million Swedish kronor (SEK). At the time, this made it the most expensive Lindgren adaptation.

Production took place in Stockholm, Moscow, Crimea, and Scotland.
