Duvall's Real-Life Mafia Encounters for 'The Godfather'

Actor Robert Duvall engaged in risky, real-life preparations before portraying Tom Hagen in the 1972 film 'The Godfather.' Sources indicate he befriended individuals with Mafia ties in New York's East Harlem, where parts of the film were shot, to grasp the criminal underworld's ethos. This immersion helped him embody Hagen's loyalty, a character adopted by the Corleone family.

Duvall's research also included meetings with actual mobsters from the Colombo and Bufalino crime families, some of whom acted as extras and advisors. This deep dive into characters, including an instance where Marlon Brando famously mooned gangsters, was typical of Duvall's methods.

His dedication to disappearing into roles was legendary. For 'Tender Mercies,' he joined a country band, and for 'True Confessions,' he embedded with police detectives. This commitment to authenticity allowed him to fully inhabit his characters, a practice described as somewhat unnerving by observers.
