”En kluven värld (1948)” (på engelska). Brittiska filminstitutet. http://www.bfi.org.uk/films-tv-people/4ce2b6ae332f6. Läst 7 april 2016. ”A ten-minute study of wild animal life in a Swedish forest; stoat, fox, hare, and owl, who stalk and savage one another, are photographed with extraordinary vividness and intimacy. It is perhaps the most striking of Sucksdorff's animal studies, in spite of an abrupt introduction and ending.”
