spoken language(s) in film
IMDb gives the language spoken in the film as being Danish, but I think the director was saying that since it was an all-Scandinavian project, each actor was in fact speaking in his or her own native language - Swedish, Danish or Norwegian - all being able to sufficiently understand the others.
I don't know any of these languages (and find all of them extremely difficult to follow, compared to the well-enunciated Hochdeutsch you hear in German films; they all sound to me as though most of their consonants are swallowed). It's my general impression that Danish and Norwegian are very similar to each other, with Swedish being rather different from either.
Can anyone confirm the language(s) spoken by the various actors? Oscarsson and Lindblom are Swedish; Federspiel, Rex, Petersen and Ottosen are Danish; Kolstad, Bjornstad, Hansen, Skjonberg, Heiberg and Fjelstad are Norwegian.
