His parents came from Italy and worked hard their whole lives. He never forgot that. Rest easy, James.
Their story
James Gandolfini was born on 18 September 1961 in Westwood, New Jersey, and grew up in nearby Park Ridge. Published forms of his full name disagree, and both are kept here rather than flattened into one invented spelling. The English Wikipedia lead gives James John Gandolfini, and its footnote says…
James Gandolfini was born on 18 September 1961 in Westwood, New Jersey, and grew up in nearby Park Ridge. Published forms of his full name disagree, and both are kept here rather than flattened into one invented spelling. The English Wikipedia lead gives James John Gandolfini, and its footnote says John is commonly attributed while some sources cite Joseph. Britannica lists him as also known as James Joseph Gandolfini Jr. The Library of Congress name authority carries a Joseph Jr. variant. His father was James Joseph Gandolfini Sr. (born Giacomo Giuseppe Gandolfini). This profile does not treat either middle name as the settled form.
His mother, Santa (née Penna), worked in high school food service and had been raised in Naples. His father came from Borgo Val di Taro in Emilia-Romagna as a toddler, worked as a bricklayer and cement mason, and later became head custodian at Paramus Catholic High School. He had earned a Purple Heart in World War II. The parents were devout Catholics who spoke Italian at home. James had two older sisters, Johanna and Leta. The Italian-American household identity stuck: he visited Italy often and carried New Jersey into almost everything he played.
He graduated from Park Ridge High School in 1979 (basketball, school plays, "Class Flirt" in the yearbook) and earned a B.A. in Communications from Rutgers University-New Brunswick in 1983, working as a bouncer at an on-campus pub. In Manhattan he bartended and managed clubs. A friend, Roger Bart, took him to a Meisner technique class. He studied for about two years under Kathryn Gately at the Gately/Poole Conservatory. Broadway came first in public notice: Steve Hubbell in A Streetcar Named Desire (1992) with Alec Baldwin and Jessica Lange, then Charley Malloy in On the Waterfront (1995). Film work followed. Virgil, the brutal enforcer in True Romance (1993), became the clip casting directors remembered. Supporting turns in Crimson Tide, Get Shorty, A Civil Action, and others kept him employed as a dangerous, funny, or wounded tough guy.
In the mid-1990s David Chase was shopping what became The Sopranos. Casting director Susan Fitzgerald showed Chase a short clip of Gandolfini in True Romance. Gandolfini left mid-audition, convinced he had not prepared right, then finished the reading later in his garage. He won Tony Soprano over other candidates including Steven Van Zandt and Michael Rispoli. From 1999 to 2007 he carried six seasons of HBO's New Jersey mob drama: therapy, panic attacks, family dinners, and violence held in the same body. Critics and colleagues later called the performance a hinge for prestige television's antihero era. He won three Primetime Emmy Awards for Outstanding Lead Actor in a Drama Series, a Golden Globe, and multiple Screen Actors Guild awards with the ensemble. By the final season he was among television's highest-paid actors. Chase would later say that without Gandolfini there is no Sopranos and no Tony Soprano.
He kept working in film during and after the series: a gay hitman in The Mexican, the mayor in The Taking of Pelham 123, General Miller in In the Loop, the voice of Carol in Spike Jonze's Where the Wild Things Are, CIA Director Leon Panetta in Zero Dark Thirty, and reunions with Chase on Not Fade Away. On Broadway in 2009 he played Michael in Yasmina Reza's God of Carnage and earned a Tony Award nomination for Best Actor in a Play. With Paramount executive Alex Ryan he founded Attaboy Films and produced HBO documentaries Alive Day Memories: Home from Iraq (2007) and Wartorn: 1861-2010 (2011), plus executive-produced Hemingway & Gellhorn. He also did USO visits with castmate Tony Sirico.
He married Marcy Wudarski in March 1999; they divorced in December 2002. Their son, Michael (born 10 May 1999), became an actor and later played young Tony Soprano in The Many Saints of Newark. After an engagement to Lora Somoza ended, Gandolfini married model and actress Deborah Lin in Honolulu on 30 August 2008. Their daughter, Liliana Ruth, was born in 2012. He kept ties to Park Ridge and supported the Octoberwoman Foundation for Breast Cancer Research. Public reporting also documented struggles with alcohol and cocaine during The Sopranos years, including missed shoots and a failed intervention noted by producers.
On 19 June 2013, while vacationing in Rome with family ahead of a planned trip to the Taormina Film Fest, he collapsed in the bathroom of the Boscolo Exedra Hotel. His teenage son Michael found him and called for help. Resuscitation continued in the ambulance and at Policlinico Umberto I; he was pronounced dead that night at age 51. Autopsy confirmed a heart attack of natural causes. New Jersey flew flags at half-staff. Broadway dimmed its lights. The funeral at the Cathedral of St. John the Divine on 27 June drew cast, friends, and public mourners. He was cremated; ashes were given to the family. Posthumous releases included the warmly reviewed romantic comedy Enough Said opposite Julia Louis-Dreyfus and the crime drama The Drop. Spike Jonze dedicated Her to him. Park Ridge renamed a stretch of Park Avenue "James Gandolfini Way." HBO aired James Gandolfini: Tribute to a Friend. The performance as Tony Soprano remains the mountain critics measure television acting against.

Exactly. Before him, antiheroes were still heroes in some way. He just was.
