duvall be nothing less than superb in this movie . i do not recall him play a more believable character ever before . the one disappointment in the movie be the church scene . i belong to a christian church with enthusiastic member and pastor . however and they do not stand around scream the same one liners the entire time and i do not recall ever be in a church that do . they usually have a message for the day and it be different all the time . i be sure some more research could have be do to make the church scenes more realistic . i might have have more compassion for e. f. situation have he gain more of my respect by give a great sermon .
