This an amazing film with a truly great cast and sound track, John Barry is a legend and can enhance any film with his musical direction. Both Voight and Hoffman play amazing parts and really bring you in and make you feel the struggle of their (well at least Voights) plight.
I highly recommend this for anyone not old enough to have seen this first time around (I was barely born). It is dark, sad, but not too depressing, with the optimism of Voights character bringing light to some situations. His naivety is endeering.
Anyway, less chat more buy.
It's as cheap as chips and you, like me, will pass this on to friend after friend
