Stars share their reaction to the unexpected death of actor James Gandolfini at 51

LOS ANGELES — James Gandolfini's fans and colleagues shared reaction to his death Wednesday:

— "I am shocked and devastated by Jim's passing. He was a man of tremendous depth and sensitivity, with a kindness and generosity beyond words. I consider myself very lucky to have spent 10 years as his close colleague. My heart goes 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." — Edie Falco, who played Tony Soprano's wife, Carmela, on "The Sopranos."

— "He was a genius. 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. He was my partner. ... He was my brother in ways I can't explain and never will be able to explain." — David Chase, creator of "The Sopranos."

— "Jimmy treated us all like family with a generosity, loyalty and compassion that is rare in this world. ... Working with him was a pleasure and a privilege. I will be forever grateful having had a friend the likes of Jimmy." — Michael Imperioli, Gandolfini's co-star on "The Sopranos."

— "I admire Jimmy as 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." — Brad Pitt, who co-starred with Gandolfini in "True Romance," "The Mexican" and "Killing Them Softly."

— "My heart goes out to his family. James was incredibly talented and I feel very fortunate to have had the chance to work with him. He was very committed during the shooting of 'True Romance.' I remember Tony Scott saying he slept in his suit in his car to stay in character. His work as Tony Soprano was flawless. It is a real loss to the creative community." — Patricia Arquette.

— "I am simply devastated. James was such an enormous talent, and an even greater spirit. I will be forever grateful for the privilege of working with him, and shall cherish his memories always." — Kathryn Bigelow, director "Zero Dark Thirty."

— "James Gandolfini was a friend and a great actor. He wrote me after portraying me last year, which was a great thrill and honor. I told him I was glad an Italian played me — swear words and all. We laughed together at the fact that tough guys can have a heart of gold. He did, and we will miss him." — Leon Panetta. Gandolfini played then-CIA director Panetta in Kathryn Bigelow's Osama bin Laden hunt docudrama "Zero Dark Thirty."

— "If Broadway has a version of a guy you want in your foxhole, Jim Gandolfini was mine. During our time together in 'God of Carnage,' we played 320 performances together. He didn't miss one. Sadly, I now miss him like a brother." — Jeff Daniels.

— "It's an awful shock. James Gandolfini was a fine actor, a Rutgers alum and a true Jersey guy. I was a huge fan of his and the character he played so authentically, Tony Soprano. I have gotten to know Jimmy and many of the other actors in the 'Sopranos' cast and I can say that each of them are an individual New Jersey treasure." — New Jersey Gov. Chris Christie.

— "We lost a giant today. I am utterly heartbroken." — Lorraine Bracco, who played Gandolfini's therapist on "The Sopranos."

— "I have lost a brother and a best friend. The world has lost one of the greatest actors of all time." — Musician Steven Van Zandt, who played Silvio on "The Sopranos."

— "Jimmy was one of the most talented, authentic and vulnerable actors of our time. He was unorthodox and truly special in so many ways. He had the sex appeal of Steve McQueen or Brando in his prime as well as the comedic genius of Jackie Gleason." — Brad Grey, a producer of "The Sopranos."

— "The great James Gandolfini passed away today. Only 51. I can't believe it." — Bette Midler on Twitter.
