Aside from young Sofia Coppola’s cameo during the baptism scene and sister Talia Shire’s primary role as Connie Corleone, other members of the Coppola family appeared in The Godfather. Father Carmine (seen above with his son) composed several pieces of music for the film and appeared as a piano player during the “going to the mattresses” montage, and the director’s two sons showed up in minor background roles.
