According to the production notes found at the Napoleon Dynamite
website (http://www2.foxsearchlight.com/napoleondynamite/), the movie
was filmed almost entirely in Preston, Idaho. However, IMDB also
lists Franklin, Idaho and Richmond, Utah as filming locations.
?The only time the production left Preston was to shoot at the sand
dunes about two hours north, another unexpected blast for Jeremy Coon.
?One of the great things about this movie is that it introduced me to
all these different little subcultures I never knew about,? he says.
?I didn?t know about sand dunes, I didn?t know about Future Farmers of
America. It was a great introduction to another side of America.??
