The character Kristoff is meant to be Sami, a member of an indigenous group that lives in northern Europe. Some viewers complained that Kristoff was not a good way to show Sami because he is light-skinned and blond. Although, today, some Sami look like Kristoff, most have darker skin and hair. When making the 2019 sequel, "Frozen II", Disney signed a contract with Sami leaders and hired Sami experts to make sure the culture would be shown respectfully.
