Watched "Paths of Glory" a couple of weeks back. Once you have watched it, it's not easy to forget it. Although the background is that of war, one may find many parallels and situations to relate it to.
I read somewhere that there was a serious discussion to convert the film's end into a happy one. However, it was not done that way, and I think that's the high point of the film.
Don't miss it - if you can't find it, borrow from me :)
