So I'm sitting at the "Iron Man" press conference, watching the trailer for the umpteenth time, waiting for Robert Downey Jr. to appear, and I'm thinking, what should I ask him if I can get a question in? Not that I will. I think most distributors have a rule now not to call on the tall, skinny guy from The Japan Times. (Probably ever since I asked Quentin Tarantino what was up with all that heroin in "Pulp Fiction" and "Killing Zoe.")
