If people have the time (and inclination) have a read of this:-

http://www.filmsite.org/twelve.html

There are several pages and like the film, a bit hard-going but thought provoking?

I don't know whether I saw the film or the TV version but I seem to remember the accused looking out of a window at a yard where the jury were taking a walk out and he saw one juror on his own away from the other 11 and the accused says something like "Thank you little man" as he realises one juror is holding out against the others.

I also seem to remember that the accused was really guilty or has time confused that film with another?
