"The Godfather" filming location- Corleone Mansion

Most of the studio filming was done on the east coast, at New York's Filmways Studios, 246 East 127th Street, East Harlem at Second Avenue. The studio has since closed down, and is now a huge supermarket called Foodways.The wedding scene, at the Corleone compound on 'Long Island', did film on an island over the water from New  – not on Long Island, but Staten Island. The outdoor festivities were staged in the garden of 120 Longfellow Road, in the affluent neighbourhood of Emerson Hill. The Corleone Mansion itself is next door at 110 Longfellow Road.The Staten Island Rapid Transit Railway will take you from St George Station, four stops to Grasmere. From here, it's about a half hour's walk north to Longfellow Road, a leafy cul-de-sac running east from Ocean Terrace. Numbers 110 and 120 are the last houses at the end of the road.
