I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: Capote Movie plot: In 1959, the four dead bodies of the Clutter family are discovered on their Kansas farm. While reading The New York Times, Truman Capote (Philip Seymour Hoffman) is riveted by the story and calls The New Yorker magazine editor William Shawn (Bob Balaban) to tell him that he plans to document the tragedy. Capote travels to Kansas, inviting childhood friend Nelle Harper Lee (Catherine Keener) to come along. He intends to interview those involved with the Clutter family, with Lee as his go-between and facilitator. Alvin Dewey (Chris Cooper), the Kansas Bureau of Investigation's lead detective on the case, brushes him off, but Dewey's wife Marie (Amy Ryan) is a fan of Capote's writing and persuades her husband to invite Capote and Lee to their house for dinner. Capote's stories of movie sets and film stars captivate Marie. Over time, her husband warms to Capote and allows him to view the photographs of the victims. The Deweys, Lee, and Capote are having dinner when the murder suspects, Perry Smith (Clifton Collins Jr.) and Richard "Dick" Hickock (Mark Pellegrino), are caught. Flattery, bribery, and a keen insight into the human condition facilitate Capote's visits to the prison where the accused are held. Capote begins to form an attachment to Smith. He informs Shawn of his intent to expand the story into a full-length book. Following the trial and conviction, Capote gains continued access to the murderers by bribing Warden Marshall Krutch (Marshall Bell). Capote spends the following years regularly visiting Smith and learning about his life, excepting a year-long stint when he goes to Morocco and Spain to write the "first three parts" of the book, accompanied by his romantic partner Jack Dunphy (Bruce Greenwood). The story of Smith's life, his remorseful manner, and his emotional sincerity impress Capote, who becomes emotionally attached to him despite the gruesome murders. Capote aids Smith and Hickock by obtaining expert legal counsel for them and initiating an appeal. Still he is frustrated, as Smith declines... My question: What is the name of the man Truman becomes friends with?
The answer to this question is:
Nelle Harper Lee (Catherine Keener)
