Ben Johnson is mesmerizing in this picture; his natural ease with
screen acting was well-honed by this time and he has a
confidence, a greasy smoothness, in the part of Bob Amory that he
hadn't displayed up to this point. Perhaps it was because he was
working with two stellar actors from the method school that
spurred him to give them a run for their money. Or perhaps he was
more relaxed due to his extensive experience working in westerns
(or because he was one of the only authentic cowboys on the set).
Nevertheless, his contribution is equal to the leads, and far above
everyone else. And that's so small feat. Before Kubrick had left the
production, he obviously installed several of his favorite players:
Slim Pickens, Tim Carey, Elisha Cook Jr in supporting roles. Each
same part makes a significant contribution to the complexity and
charm of the story. But Johnson rises above them all. His snake- rattling Amory is just as pathetic as he is creepy. The scene in
which he chickens out of a gun duel with Brando is electrifying,
mostly due to the ambiguity in Johnson's close-ups. Watching it,
you're not quite sure if the character is too stupid to back down or
just plain chilled to the bone with fear.
