U.S. actor James Gandolfini, who portrayed an emotionally vulnerable crime boss on the television drama "The Sopranos," has died at the age of 51 while vacationing in Italy.
Doctors at a Rome hospital say he died of an apparent heart attack after resuscitation efforts failed. He was was to attend a film festival in Italy.
Gandolfini won three Emmy Awards for playing Tony Soprano, a violent mobster undergoing psychiatric care in secret.
Sopranos creator David Chase called Gandolfini a genius and one of the greatest actors of our time. His Sopranos co-star Edie Falco said, unlike Tony Soprano, Gandolfini was kind and generous beyond words.
The New Jersey native starred in such movies as "The Last Castle" with Robert Redford and" All the King's Men" with Sean Penn. Last year, Gandolfini played CIA Director Leon Panetta in the Osama Bin Laden manhunt movie "Zero Dark Thirty."
New Jersey Governor Chris Christie mourned Gandolfini's death, calling the actor "a true Jersey guy."
U.S. Senator John McCain said Gandolfini was "one of the nicest guys I've ever met."
