Trollhunting!

This short film from BBC Earth gives a fascinating insight into Icelandic folklore. Icelanders sort-of believe that their landscape is inhabited by hundreds of trolls. They are key figures in a national story, and seem to be discussed much as soap opera characters are by urban Brits. Like fairies in rural Ireland, trolls have their places and their ways, and to cross them invites bad luck. The film is full of beautiful images of a fascinating place, and it's easy to see why the legend of the trolls took root on an island that manages to be cold and stark yet oddly welcoming.

Icelandic trolls come across as fairly pleasant, rustic types. Norwegian trolls, though, seem to be just plain badass.
