The Shootist (1976)

John Wayne plays an ageing shootist whose life is winding down. It was his final film and served as a fitting tribute to the big man while simultaneously marking the end of an era in style.
Wayne gives an understated performance filled with empathy because the same disease that plagues his on-screen character was killing him slowly in real life. When he looks tired, it's probably because he was.
It was The Shootist that convinced me The Duke was the 'Giant' that folks said he was when I first saw it over twenty years ago, and of all the classic John Wayne films that I've watched since it's still my favourite.
