Sopranos star James Gandolfini isn't taking sides against his TV family. The star of HBO's mob hit — which kicks off its third season on March 4 — reveals that if the show's creator, David Chase, makes good on his threat to pack it in at the end of next season, he'll follow suit. "I'm committed to one more year. I'll do that and then we'll see," Gandolfini tells TV Guide Online. "David Chase has said he's definitely going to leave, and if he goes, I go — that's for sure."
