Gandolfini is a wonderful actor, Pube. Incredibly committed to the craft. Very good in True Romance, very good in Crimson Tide, respectable in Fallen, good in The Mexican (even though the rest of the film is total ****), and I'm very interested to see him in the HBO Hemingway biopic. He doesn't work very much, and when he does, he occasionally gets awful material (The Last Castle comes to mind, though I think he just jumped at the chance to work with Bob Redford), but the dedication he's put in to Tony Soprano -- the body language, the subtle gestures, the believable moments of both tenderness and rage -- has been awe inspiring. Without Gandolfini properly expressing Tony's deeply divided psyche and his infinite moral ambiguities, that show would never have received the kind of universal praise its gotten. He'll be just fine. So will Michael Imperioli and Edie Falco.
Of all the people who should be begging for a Sopranos movie or an additional season, I'd put Robert Iler, Jamie-Lynn Sigler and Lorraine Bracco in an unbreakable three-way tie for first.
