First ever animated film which used Lego. As such is often considered a first ever brickfilm (a genre of animated movies which uses Lego for stop-motion which mostly took off in the Internet much later). A much later effort The Magic Portal (1989) is at times mistaken for a first, despite arriving full sixteen years later.
Made as a gift for directors grandparents golden wedding anniversary.
Directors grandparents insisted on showing the film to Lego. CEO of Lego, Godtfred Kirk Christiansen, met with filmmakers, then aged 12 and 10 personally and, after the screening they were presented with Lego sets and a tour to factory.
