The sudden death of Emmy Award-winning actor James Gandolfini has taken the Broadway community by surprise. Gandolfini was nominated for a 2009 Tony Award for his performance in the Broadway debut of Yazmina Reza's God of Carnage. His co-stars in that show, Jeff Daniels and Marcia Gay Harden, took to Twitter to express their grief.

Gandolfini is best known for his portrayal of mob boss Tony Soprano on the HBO series The Sopranos. His co-star Steven Van Zandt also mourned the loss of his friend and colleague:

Edie Falco, who played Tony Soprano's wife, Carmela, released the following statement through Showtime:

"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 ten 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."

Below is a gallery of photos of Gandolfini from his run in God of Carnage, a play about two sets of parents who try to civilly resolve a dispute between their young boys and end up proving that adults can be much worse than children:
