A few minutes ago, I saw the “world premiere” of the trailer for Disney/Pixar’s Cars (June 9). Owen Wilson sounded over the top. Paul Newman was appropriately world weary, but then he elevates any material. Talking cars taking Route 66 may be the end-all-and-be-all for little and big boys, and NASCAR junkies. But the trailer seems too retro. I don’t think this is gonna be Pixar-Disney’s most praised or most profitable.
