Don't try an overload of film noirs. Very bad idea. I've done it twice, once at a three day festival at an art house and a second time for the film society I ran in film school. You'll be thinking the worst of people and searching for ulterior motives for days afterwards.

Also don't watch a bunch of 60's/70's paranoia and conspiracy films too close together. The Parallax View is disturbing enough, but don't follow it with fare such as Night Moves, and John Frankenheimer films. You won't sleep easily.
