Many of the filming locations took place in Preston, Idaho, including Napolean's home and the high school. Preston is also the city where film scouts came across an orange, 1975 Dodge Tradesman, and asked to use it for a character.
I know, I live in Idaho and I feel like I am going to get in trouble for saying it, but the movie Napoleon Dynamite was not good. With the election why not get a little more divisive on things that are simple and fun. I stand behind my unpopular opinion.
