The Hollywood community reacted with shock and sadness on Twitter late Wednesday over the sudden loss of James Gandolfini, who died at the age of 51 of a possible heart attack.

Jesus. The world just lost one of its great actors. James Gandolfini has passed away. Thoughts to his family. Such a talent. I'm saddened.--

James Gandolfini. You created an icon. And you cut to black way too abruptly. Thank you, and rest in peace.--
