Indiana Jones and the Raiders of the Lost Ark
This post may contain mild spoilers or may not, and I don't really care, so read it at your own peril. Can you even spoil a movie like this?
This movie is really a reflection of a couple of things that are exceedingly prevalent in American cinema. It isn't a perfect, straightforward example of it, like Die Hard might be, but it's up there. Americans, as shown by their movies, care about a few things in particular more than other cultures do:
1. Individualism is Best
2. Government Conspiracies/Laws and Bureacracy Are Bad
3. Underdogs Must Win
Now, other cultures can certainly care about these things also; some care about particular elements a lot. But in American movies in particular, these are HIGHLY dominant traits, especially and most obviously in action films. Indiana Jones basically hits the nail(s) on the head here.
First off, he's clearly "in it for himself." He works alone, he's not part of some team, and he's trying to find things for his personal enrichment (in his case in particular, mostly knowledge). He isn't trying to achieve a greater good for society in particular. He's unique, non-conformist, and a Solo Badass Hero like so many others in movies.
Second, like most action heroes, rules and regulations don't apply to him; he needs to fight through the red tape to just do what's right, and the Government (almost always the Government) which should be on his side in the fight against the Nazis exists only to slow him down, and box up his Ark. One of the iconic lines of the movie ("Top Men") is a pretty clear and direct indication of the role of Government in this movie and most other American films; it purportedly exists to "help," but in practice it's a giant sinister shadow organization that is probably evil itself and just wants to hinder the Heroic Individual.
Third, most obviously, he's a constant underdog, having to fight off or escape large groups of better-armed people at all times. This one really needs no explanation, but it's worth noting that not all cultures care so much about the lesser, weaker force winning.
And there are guns and fists and stuff, too.
