it’s a long shot, I was very little,
the plot of the movie is about a very young boy for the reason I don’t remember found himself alone in some kind of wildness ( it was like desert kind of wild and not a forest) and an old and lonely man who lived in this area by himself and found the boy, took him and thought the boy survival skills for few years.
I remember vividly a scene which the old man and the boy going to a water source and the old man laying on a rock waiting for a fish to come by and then catch it with bare hands and it use next to feed both of them,
then I remember the boy grows older mastering everything the old man thought him, and they had an argument and the old man was too old and slow to hunt and fish for himself and the boy caught a fish and didn’t share with the old man because he was made at him.
at the end the old man got sick or too old, and the boy regret his anger and took care for few days for the old man in his bed, after a while the old men died, the boy cried and there is a zoom out from the old man wooden house, and you can see pigeons flying.
I watched the movie somehow between 91-95, I believe the movie is from the year of 85-90 I pretty sure the movie was in English, the boy was white, for the old man he was white or Asian
