"Thank you, Arthur. Thank you for my children."
For his performance as Atticus, Harper Lee gave Gregory Peck a pocket watch that belonged to her father, the man Atticus was based on. When Peck accepted his Best Actor award, he was wearing the watch.
For added points, the watch was stolen from Peck's bag at a train station one day, and he was so ashamed that for years he didn't admit it to Lee. When she finally did find out, however, she didn't make a big deal of it because: "It's just a watch."
Mary Badham, who played Scout in the film, kept in contact with Gregory Peck after the filming ended. She would always call him "Atticus".
The scene added for the film where Scout and Jem discuss their memories of their mother, as Atticus silently listens.
