In a Facebook post from 2016, director André van Duren commented that he considered this film his "most successful" so far, even though "it rained every day" during production in autumn. He said this was thanks to "the wonderful script, but most of all the terrific acting of Laurien Van den Broeck. In an early 2000 interview with de Volkskrant newspaper on the set, he had already remarked that "with child actors, you often have to piece together scenes shot by shot, but not with Laurien. She can really act and knows how a film set works".
