Just the tone of the conversation between the two characters shows the acting depth of John Wayne and Ben Johnson. No flowery speeches, exaggerated arm or hand gestures or special lighting. Just two actors playing a scene with simplicity and honesty. Watch "The Last Picture Show" and enjoy Ben Johnson portraying the same simplicity and honesty in his Oscar winning role. And watch John Wayne's face in any of his movies (well, except "The Conqueror.") With just the slighest movement in his face or a slight glance, maybe a shift of his body conveys so much in his reponse or reaction by his character. Underrated is an understatement.
