Call Northside 777 is a 1948 documentary-style film noir directed by Henry Hathaway. It is based on the true story of a Chicago reporter who proved that a man in prison for murder was wrongly convicted 11 years before. The names of the real wrongly convicted men were Majczek and Marcinkiewicz for the murder of Chicago Traffic Police Officer William D. Lundy. James Stewart stars as the persistent journalist and Richard Conte plays the imprisoned Frank Wiecek. Wiecek is based on Joseph Majczek, who was wrongly convicted of the murder of a Chicago policeman in 1932, one of the worst years of organized crime during Prohibition.
