To search directly in the newspaper databases, input the name of your film in quotation marks, i.e. "The Magnificent Yankee" and review. You will likely need to limit your search results by date to the year of the film's release.
These freely available websites bring together reviews published in a variety of established and not-so-established online sources. Choose your reviews carefully, and try to learn as much as possible about the source that published them.
