I might suggest a little Guy Richie called Revolver to be added to the list.
In it, the main character realises that his inner voice, that had being guiding him throughout the film, is in fact his true enemy, it is what always makes him anxious in threatening situations and makes him flip on occassions. A scene in a elevator shows him ' fighting ' with his inner voice and winning. The final scene of the film ( after he overcomes his inner voice ) shows him in a threatening situation but he is not anxious at all anymore. I'm crap at explaining things but its worth seeing, for that alone, I think.
I also recently saw Fight Club, I won't say much as it will spoil the film. But the Brad's character is indeed a good one, one who doesn't give a F*** about anything and as well as encouraging to look at society in a different way. I don't like the whole ' giving up all hope ' ideal but I agree with the ' You are not specail! ' idea, though.
