In 2003, AFI named Atticus Finch the greatest movie hero of the 20th century. To Kill a Mockingbird marks the film debuts of Robert Duvall, William Windom, and Alice Ghostley. The film's young protagonists, Jean Louise "Scout" Finch (Mary Badham) and her brother Jem (Phillip Alford), live in the fictional town of Maycomb, Alabama, during the 1930s. The story covers three years, during which Scout and Jem undergo changes in their lives. They begin as innocent children, who spend their days happily playing games with each other and spying on Arthur "Boo" Radley (Robert Duvall), who has not been seen for many years by anybody as a result of never leaving his house and about whom many wicked rumours circulate.
