an old friend who lives in London (I live in Canada) is a film producer, quite successful at this time. In the early days of her career (1960's), she was involved in the production of a black and white film about a boy and his hawk called Kes. It was an obscure film, probably lost forever now. I know about it because my friend told me about it and that it was, out of all her productions, the one she was most proud of.
My friend and I talk about once a year by phone and catch up.
