in my opinion and robert duvall performance make this story into a believable movie and and turn his character into a man of understated strength and and an admirable person . he manage to capture the mannerism and accent and and speech syntax of his character and the region to the extent that the other actor otherwise good portrayal appear out of place . i be not sure that i would have see the movie and have i read the story first while however and have see the movie and i want to read the book .
