Lawman (1971)

Synopsis
In Lawman, Burt Lancaster is Jered Maddox, a dedicated marshal with an inflexible adherence to upholding the law at all costs. Riding into a nearby town to pick up a group of local carousers who, during a drunken spree, killed an old man, Maddox meets up with Vincent Bronson (Lee J. Cobb). Bronson is the local town boss, and Maddox discovers that the men he is looking for work for him. Unlike most western heavies, Maddox, although he is powerful and unscrupulous, abhors violence. But violence is something Maddox cultivates. A major confrontation between the reluctant Bronson and the intransigent Maddox builds -- particularly when Maddox enlists the help of weak-willed local sheriff Cotton Ryan (Robert Ryan). ~ Paul Brenner, All Movie Guide
