Fan Casting Teresa Hagen in Martin Scorsese's The Godfather

Theresa was born to two immigrant Sicilian parents, who Tom Hagen and the Corleone family would later help when they faced legal trouble to their being Italian non-citizens during World War II.[2] Theresa met Tom Hagen and married him in the late 1930s. They never divorced, despite Tom's affair with Judy Buchanan, although they were known to have had near at least one break-up and tumultuous arguments over Tom's affair and his business life, though they always reconciled.[3] She was particularly close to her informal sister-in-law, Sandra Corleone. She was a college graduate, intelligent, and articulate. She was an expert in art.
