The movie is generally considered a disaster, both on and off screen. Main actor Poul Bundgaard and director Tom Hedegaard both died during production, Benny Hansen who appeared briefly as a hospital porter died two days after the end of filming, and veteran actor Bjørn Watt-Boolsen, who had appeared as the evil mastermind in most of the previous movies in the series, died just 10 days after opening night. The movie itself was generally scolded by critics, and even Olsen Gang creator and script writer Erik Balling later regretted having made it.[1]
