David Carr, the N.Y. Times Carpetbagger guy, tried to dimiss Walk the Line as a Best Picture contender this morning. Or has this Johnny Cash biopic in fact lost serious steam? That would be news to me, but maybe I’m not talking to the right people. Carr back- handed Jim Mangold’s film with stealth and without seeming too aggressive. He merely said it “has faded from memory, perhaps because it was not that memorable of a film.” Maybe…but it’s the only the Best Picture contender on the short list that’s certain to top $100 million, and isn’t there some kind of interest in having at least one Best Picture contender be a popular hit?
