An essay about a movie with strong ideology

Does anyone have a suggestion on a movie to watch with strong ideology? Have to have 6 page essay in less than 2 weeks, it has to be based on a movie.

V for Vendetta
X-Men
The Watchmen

In fact, virtually all movies probably have a certain amount of ideological underpinnings, but those three should be fairly easy to analyze.

Pay it Forward!!

I guess I'm really confussed on what an ideology is? This is driving me crazy! I could really use some pointers as to what to look for when watching a movie. I'm not a big movie watcher, I generally read if I have any time. This paper has to be at least 5 pages, and is going to count for a large part of my grade.

What is ideology?? Need to find them in a movie & write 5 pages. I'm lost!

Can someone explain ideology to me & how I can detect them in a movie?

An ideology is a coherent system of ideas. Objectivism, Marxism, Fascism, Feminism, etc. are all ideologies. Notice that all of these words end in "ism," which is a fairly common suffix handy for identifying ideologies. Most movies reflect the beliefs and ideas of the people who make them, so finding ideologies in movies shouldn't be that hard.
