not seen since 70s

It is odd that some films get repeated ad nauseam and others seem to be rarities. I am 53yo and remember seeing this as teen or pre-teen somtetime in the 70s I guess and I still remember it. It would be good to see it again as it was interesting enough for me to remember it all these years - I always think of it when I see Hal Holbrook (yep he is still making movies) :-)
