Not a movie but a series of TV documentaries, I've been watching everything Adam Curtis has made thats up on google video this past week. Totally mindblowing stuff.
The Trap - Basically about Game Theory and how the ideas have crept into the modern world to create a very limited idea of freedom.
The Century Of The Self - Mostly about Edward Bernays/PR/propoganda and Freud and how these ideas have changed "the american citizen" to the "american consumer".
The Power of Nightmares - Mostly about the neo conservatives/Leo Strauss vs radical islam and how these ideas are shaping the world.

if you just search for the titles or Adam Curtis on google video and filter for "long" they should come right up.
