12 Angry Men sticks in my mind as being one of the most thought provoking films I ever watched in my life. I think it should be under a thread 'Films you must watch before you die' not just because of the racial side but how different moods and attitudes of a jury could so wrongly convict someone on trial. I have never been on jury service but if I did I would refer to that film before doing so.

RIP Sidney Lumet.
