One of Gregory Peck’s greatest roles is Atticus Finch, a small-town Southern lawyer who takes on the establishment when he is appointed by the court to defend Tom Robinson, a black man accused of raping a white woman. His daughter, Scout, watches the trial unfold and learns about the complicated relationship among truth, justice, and the justice system in a fallen world. One of the most enduring stories of American literature and cinema, it’s freshly relevant today as police shootings and arrests of African-American citizens take center stage in public discussions of criminal justice and the legacy of slavery in the United States.
