 DATE: In a scene Capote complains that he has been on the In Cold  Blood case for four years. In the next scene he is invited to a  party celebrating the movie version of Harper Lees  _To Kill a Mockingbird (1962)_ (qv). But four years after the  murders would have been late 1963, and four years after he met the  murderers in January 1960 would have been at least 1964.
