Vincent Pastore, who played Tony Soprano's best friend turned FBI informant on HBO's prestige drama The Sopranos, has died aged 80.
Pastore, who was best known for his portrayal of Salvatore Bonpensiero in the acclaimed mob drama, died at his home in New York, his manager said.
The veteran actor had appeared in films since the 1980s, including roles in Goodfellas and Awakenings, and made a name for himself portraying gangsters and tough guys.
But it was his 30-episode stint in The Sopranos as a cigar-smoking mob enforcer turned conflicted informant that brought him fame.
A cause of death has not been disclosed.
Pastore's manager Robert Attermann told Sky's US broadcasting partner NBC News that the actor will always be remembered as his "unforgettable" character in The Sopranos.
"To the world, he will always be remembered as the unforgettable 'Big Pussy'," he said, using the nickname of Pastore's character in The Sopranos.
"But to those of us who knew him, he was so much more."
Another of Pastore's managers, Bob McGowan, said he had learned of the star's death on Saturday from another client and actor, Vincent Curatola, who portrayed mafioso Johnny Sack on The Sopranos.
He said that Pastore had been found in his home on New York's City Island in the Bronx after not being heard from for several days.
McGowan said he'd been trying to reach Pastore about a possible job.
"He was the most loyal client and he always gave to charity," he said.
"And he was the kind of guy who would help anybody, which is rare in my business."
Pastore was born in the Bronx and grew up in suburban New Rochelle, New York.
He enlisted in the Navy during the Vietnam War and later attended Pace University, according to his biography on IMDb.
He is survived by his daughter, Renee Pastore.
