MawtheMerrier, is Faroese like Old Norse, I wonder? I do notice in the subtitles that they use a letter I associate with Anglo Saxon, can’t remember what it’s called though.
On a related topic, I remember reading (or hearing, probably on Melvyn Bragg’s Routes of English) that during WW2 some U.K. airmen found themselves in Iceland for a while. They were from Cumbria (IIRC) and apparently found that their home dialect allowed them to understand Icelandic at least at a basic level. Their home dialect evidently had its roots in the Vikings’ Old Norse - same as the Icelanders, presumably.
