LOS ANGELES (AP) -- James Gandolfini's lumbering, brutish mob boss with the tortured psyche will endure as one of TV's indelible characters.
But his portrayal of criminal Tony Soprano in HBO's landmark drama series "The Sopranos" was just one facet of an actor who created a rich legacy of film and stage work in a life cut short.
Gandolfini, 51, who died Wednesday while vacationing in Rome, refused to be bound by his star-making role in the HBO series that brought him three Emmy Awards during its six-season run and helped change the landscape of television drama.
"He was a genius," said "Sopranos" creator David Chase. "Anyone who saw him even in the smallest of his performances knows that. He is one of the greatest actors of this or any time. A great deal of that genius resided in those sad eyes."
Dr. Claudio Modini, head of the emergency room at the Policlinic Umberto I hospital in Rome, said Gandolfini suffered a cardiac arrest and was pronounced dead at 11 p.m. Wednesday after resuscitation efforts in the ambulance and hospital failed.
Modini told The Associated Press that an autopsy would be performed starting 24 hours after the death, as required by law.
Michael Kobold, a family friend, told reporters in Rome that a family member discovered Gandolfini in his hotel room, but he declined to say whom. NBC quoted the manager of Rome's Boscolo Exedra hotel as saying it was Gandolfini's 13-year-old son, Michael.
Gandolfini had been expected to receive an award at the Taormina Film Festival in Sicily this weekend, and organizers said they were scrambling to instead put together a tribute "remembering his career and talent."
Edie Falco, who played Tony Soprano's wife Carmela on "The Sopranos," remembered him as a "man of tremendous depth and sensitivity."
"I am shocked and devastated by Jim's passing," she said in a statement, adding that her heart went out to his family "as those of us in his pretend one hold on to the memories of our intense and beautiful time together. The love between Tony and Carmela was one of the greatest I've ever known."
Joe Gannascoli, who played Vito Spatafore on the drama series, said he was shocked and heartbroken.
"Fifty-one and leaves a kid -- he was newly married. His son is fatherless now. ... It's way too young," Gannascoli said.
Gandolfini and his wife, Deborah, who were married in 2008, have a daughter, Liliana, born last year, HBO said. Michael is the son of the actor and his former wife, Marcy.
Gandolfini's performance in "The Sopranos" was his ticket to fame, but he evaded being stereotyped as a mobster after the drama's breathtaking blackout ending in 2007. In a December 2012 interview with The Associated Press, he was upbeat about the work he was getting post-Tony Soprano.
"I'm much more comfortable doing smaller things," Gandolfini said then. "I like them. I like the way they're shot; they're shot quickly. It's all about the scripts -- that's what it is -- and I'm getting some interesting little scripts."
He played then-CIA director Leon Panetta in Kathryn Bigelow's Osama bin Laden hunt docudrama "Zero Dark Thirty."
"I told him I was glad an Italian played me -- swear words and all," Panetta said Thursday. "We laughed together at the fact that tough guys can have a heart of gold. He did, and we will miss him."
Gandolfini also worked with Chase for the '60s period drama "Not Fade Away," in which he played the old-school father of a wannabe rocker. And in Andrew Dominick's crime flick "Killing Them Softly," he played an aged, washed-up hit man.
Brad Pitt, his co-star in that film, called him "a ferocious actor, a gentle soul and a genuinely funny man. I am fortunate to have sat across the table from him and am gutted by this loss. I wish his family strength and some semblance of peace."
On Broadway, he garnered a best-actor Tony Award nomination for 2009's "God of Carnage."
Deploying his unsought clout as a star, Gandolfini produced a pair of documentaries for HBO focused on a cause he held dear: veterans affairs.
His final projects included the film "Animal Rescue," directed by Michael R. Roskam and written by Dennis Lehane, which has been shot and is expected to be released next year. He also had agreed to star in a seven-part limited series for HBO, "Criminal Justice," based on a BBC show. He had shot a pilot for an early iteration of the project.
