I don't know, he way he walked in, it felt more to me like he was surprising the audience. I've seen quite a few of these kind of videos where an actor or director goes into a theater to surprise fans on opening night, but I think this one is probably had the most subdued reaction from the crowd.If he's showing up, I would have to assume it's a paid engagement to have him appear as part of the movie's rollout. You often see this kind of thing via the movie festival circuits accompanied with a Q&A period.
