Yes, he hinted that it would be his last western.
Did you ever see "Second Hand Lions" with Duvall and Michael Caine? That also is an excellent film; so good we bought it to watch over and over again. Same thing in that movie...good characters, good scenery, etc.
Yes, I have seen Second Hand Lions. Enjoyed it. I can say I have never seen a Duvall movie that I have not enjoyed. His subtle expressions, especially in Broken TRail and Lonesome Dove, remind me of my mothers' father. Few words. Everything he said was for a reason. Didn't say anything if he had nothing in particular to say. Quiet unassuming hero types. Duvall, as Gus, or in Broken Trail, always had mischevious side to him and he never got too far away from it, though he often used his mischieviousness to make a serious point.
From the greenist pastures to the packing house, from eternity to eternity.
