Ejnar Mikkelsen (1880-1971) was a veteran of expeditions to Arctic Greenland, Siberia, and Alaska before directing the ill-fated Alabama expedition. Following that ordeal, Mikkelsen continued to lead expeditions to the "earthly paradise" of Greenland in 1925 and 1932. He made his final trip to that same stretch of inhospitable coast in 1964; by this time Greenlanders were addressing him affectionately as "Grandfather." Nikolaj Coster-Waldau is a Danish actor and producer who co-adapted Mikkelsen's classic Arctic survival story into the Netflix feature film in which he also stars. Widely known for his work on Game of Thrones, Coster-Waldau is a UNDP Goodwill Ambassador, drawing public attention to issues such as gender equality and climate change.
