NEW YORK (AP) -- There was no decisive moment, no seismic shift, no ceremony when James Gandolfini put "The Sopranos" behind him. But he has. Comfortably.

"I was told that it would be a transition," he says and shakes his head. "Not much. It's very calming to move on."

Gandolfini, of course, had played gangster-in-therapy Tony Soprano -- earning raves, clout and unsought celebrity -- since the HBO drama premiered in January 1999. (HBO, like CNN, is a unit of Time Warner.)

Now there's only one piece of unfinished business. The finale, which airs Sunday at 9 p.m. EDT, will bring to a close a saga as powerful and oddly relatable as anything ever seen on TV. This conclusion, however satisfying or disappointing, will surely leave "Sopranos" fans wanting more. (Gallery: A guide to "The Sopranos") Read More.
