To Kill A Mockingbird (1963)

Faithful adaptation of powerful Harper Lee novel, both an evocative portrayal of childhood innocence and a denunciation of bigotry. Peck's performance as southern lawyer Atticus Finch defending black Tom Robinson (Peters), who's accused of raping a white woman, is flawless. Duvall debuted as the dim-witted Boo Radley. Lee based her characterization of Dill, the Finch children's goin' on seven friend, on Truman Capote, her own childhood friend.
