> In fond memory of his debut role in the film, Robert Duvall named a succession of his dogs Boo Radley.

> Gregory Peck was reunited with actress Collin Wilcox, who played the slattern Mayella Violet Ewell in To Kill a Mockingbird, when they both appeared in HBO's The Portrait (1993).

> Producer Alan J. Pakula directed many fine films such as Klute (1971), All the President's Men (1976), Sophie's Choice (1982), and Presumed Innocent (1990).

> The uncredited actress who serves as the narrating voice of the adult Scout is Kim Stanley. An intense Method actress, Stanley won critical acclaim for performances on Broadway and the London stage before turning to film work. While she has only made a handful of films, she earned an Oscar® nomination for Best Actress for Seance on a Wet Afternoon (1964). Shortly after the release of this film, Stanley suffered a nervous breakdown and temporarily retired from film acting.

> Up until the release of To Kill a Mockingbird, African-American actor Brock Peters was typecast as villains. Peters told a reporter in 1964, "Producers didn't want to see me. They had liked my performances but couldn't see me as anything but a heavy." That all changed when Robert Mulligan and Alan J. Pakula cast him as Tom Robinson, a Southern black man who stands accused of raping a white woman. Peters's performance shattered his typecast and deeply impressed a number of critics.

> John Megna, playing the neighborhood friend Dill, also made his film debut in To Kill a Mockingbird, although he had some stage experience in the Broadway production of All the Way Home. Megna's unique character in the film is based on author Truman Capote, a childhood friend of Harper Lee's.
