also the movie also contains parts of Sami and Viking culture. there is a scene where books with runes were shown, and a scene where there is singing in Old Norse (the conoration scene). The Intro of Frozen is a joik, or an acapella-like style of singing among The Sami people. In frozen 2, the Northlunda people represent Sami people very well (the outfits arent accurate because Sami people's traditional dress (The Gåkhti) is usually extremely colorfull. There are also references to the Sámi religion (They belived that everything had a spirit acossiated with the 4 elements) and the Norwegian-Sami conflict (in the 1930s, Norwegians forced Sami people to speak Norwegian, and this led to conflict and it is now a law to have a Sami dubbing in Norwegian children's shows)
