Question: I know this film is supposed to be set in 2004-2005, but does anyone know why the clothes and some of the music seems to be quite old (like 20-30 years ago)?
Answer: The reason the styles and such are so out of date is to signify that the town where "Napoleon Dynamite" takes place is a very small town that is out of touch with current fads and trends. The aged styles also serve to create a sense of nostalgia to the majority of the viewing audience.
Question: What was Napoleon putting in his mouth in the restroom during the dance? It looks a chewing tobacco pouch that he takes it from, but since he swallows it seconds later, this seems implausible.
Answer: On the DVD commentary, they say it's Big League Chew, that shredded bubble gum that comes in a pouch.
Question: What is the point/moral of this film. To me it was just a random funny movie but I was wondering if there was a point.
Answer: The movie's point is that no matter who you are, you can still be a winner. The movie was inspired by the short film "Peluca" that was also made by Jared Hess in 2003.
Question: Why do Napoleon and Kip live with their grandmother, what exactly happened to their parents?
Answer: This is never explained or referenced.
Question: Does anybody know what music the Mexicans are playing in their car? I like it.
Answer: It is a cut/mix of "So Ruff, So Tuff" by Roger Troutman (lead singer of Zapp). I think this is a extended mix of it. It contains the beginning of Zapp's biggest hit "More Bounce to the Ounce" which was off their first self-titled album "Zapp" (1980). This has been used and sampled in Hip Hop songs for over 20 years. Roger Troutman put out his first solo album the next year in 1981 (Many Facets of Roger). This contained the single "So Ruff, So Tuff".
Question: Why did Trisha's mom force her to go to the dance with Napoleon?
Answer: When Uncle Rico is selling stuff to Tricia's mom, he mentions how Napoleon has had a hard life. (I believe he talks about how Napoleon lost his parents or something to that extent, if I remember correctly.) Tricia's mom feels sorry for Napoleon, and makes Tricia go out with him.
Question: Who is the woman on the bike that rides up and meets Uncle Rico toward the end of the movie? Is she Tammy, his previously mentioned girlfriend? If so, what is the significance of this scene and why is this her only part?
Answer: I believe it was his estranged wife coming back to him. The only significance is that 'in the end, everything will be ok.'
