Question: was the secret life of walter mitty filmed in iceland

Answer: Yes, The portions of the film set in Nuuk, Greenland, were in fact shot in Stykkishólmur, a village on the Snæfellsnes peninsula in Iceland, and Höfn, a village in southeast Iceland. Later sequences set in Stykkishólmur were actually filmed in Seyðisfjörður. The sequences where Walter Mitty follows Sean to Afghanistan were also filmed in Iceland, at the Skogafoss waterfall and in Vatnajökull National Park.
