What is the name of the actor who plays Carlo Gervasi?

The actor who plays Carlo Gervasi is Arthur Nascarella.

Carlo Gervasi is a minor but important figure in The Sopranos, appearing as a soldier in the DiMeo crime family. He becomes more prominent during the final season, when pressure from law enforcement and the family's internal tensions affect his loyalty.

Arthur Nascarella is an American character actor whose work has often centered on crime dramas and stories about organized crime. His performance as Carlo fits the show's wider pattern of using performers with convincing New York and New Jersey streetwise personas.

Carlo is sometimes confused with other Sopranos mobsters because the series features a large ensemble cast, including Frank John Hughes as Walden Belfiore and Joseph Siravo as Johnny Boy Soprano. Those are separate characters played by different actors. Nascarella's role is also distinct from John Ventimiglia's Artie Bucco, a civilian restaurateur rather than a mob soldier.
