Bruno Tattaglia is the Underboss of the Tattaglia family following the death of Johnny Tattaglia in 1946. He was portrayed by Tony Giorgio.
Bruno was the son of Don Phillip Tattaglia, head of one of New York's Five Families and owner of The Luna Bar nightclub. He considered men like his father to be things of the past, and was seeking a way to modernise his Family.
Along with business partner Virgil Sollozzo, he struck the first blow in the war with the Corleone family by helping murder Corleone enforcer Luca Brasi, who had met with Bruno to try and infiltrate the rival faction.
Bruno later provided assistance to Sollozzo via his friendship to Captain Mark McCluskey, who became Sollozzo's bodyguard, and later assisted them in attempting to finish off Don Vito. The attempt failed, and a furious Sonny Corleone lashed out, murdering Tattaglia in his own nightclub.
