Like Drums Across the River, Bad Day at Black Rock (January 7, 1955), is a revisionist work--this time examining the seamy side, the racism and thuggery--of postwar America. Brennan, looking much slimmer than in his previous pictures, plays a western town's veterinarian and mortician. This taut drama, featuring menacing performances by a trio of villains (Robert Ryan, Ernest Borgnine, and Lee Marvin), ultimately centers on Brennan's character (Doc Velle), who collaborates with John J. Macreedy (Spencer Tracy) to uncover the truth about Komoko, a Japanese American settler killed during the war. Doc Velle, like the rest of the town, has been cowed by the xenophobic Robert Ryan-led conspiracy to thwart and ultimately murder Macreedy after he refuses to relinquish his quest for the truth--even though he is outnumbered and apparently incapacitated because of a paralyzed arm (presumably a war wound). Brennan's Velle is no hero, but he is a man who can no longer abide his association with evil--any more than can Tim Horn (Dean Jagger), the town's sheriff. Shorn of his sidekick status and of any mannerism reminiscent of his more comic roles, Brennan emerges as the common man's powerful and utterly believable voice of conscience.
