Film reviews, or journalistic articles from the time your film was produced can be useful for research.
Because this assignment is focused on four older films, Atonement, The Godfather, The Shawshank Redemption, and To Kill a Mockingbird, it is suggested that you use Film & Television Literature OR The New York Times Historical in order to retrieve the older articles.
Here is an example review of The Godfather, published in March 1972, retrieved from ProQuest Historical Newspapers: The New York Times:
