John Wayne — showing off a darker side to his screen persona than we’d previously seen -- portrays Thomas Dunson, a frontiersman who, with his longtime partner Nadine Groot (Walter Brennan), abandons a westbound wagon train in 1851 to make his future as a rancher in Texas.

He's able to hold them in line as long as Matthew backs him up, and he does until Dunson, exhausted and worn down by lack of sleep, finally goes too far. Matthew steps in, backed by laconic, smirkin...
