Wie alt waren die Schauspieler in Emigranten (1971)?

Karl and Kristina Nilsson work on a farm in a cold and desolate area of 19th century rural Sweden. Growing privations, combined with increasing social and religious persecution, motivate the Nilssons and many of their neighbors to strike out for the United States. Following a treacherous ocean crossing and an equally grueling land passage, the emigrants find themselves in seemingly idyllic Minnesota.
