I saw this film at the cinema in the UK in 1972. I remember being pretty shocked and disturbed by it. Actually, I think it helped to keep me on the straight and narrow (more or less) when I spent a year in the States some years later! There was no way that I wanted to end up in an American nick! 1972 is a long time ago and my memory is not what it was, nevertheless the film has stayed with me and I often mention it when discussing contemporary films. I would love to see it again and recommend it to anyone with a strong stomach. Scum - a British film set in a borstal, which was made round about the same time, is also with looking out for.
