To the casual observer, the Dropbox demo video looked like a normal product demonstration, but we put in about a dozen Easter eggs that were tailored for the Digg audience. References to Tay Zonday and 'Chocolate Rain' and allusions to 'Office Space' and 'XKCD.' It was a tongue-in-cheek nod to that crowd, and it kicked off a chain reaction.
Some directors don't say much. Michael Mann, for example. I remember on 'The Insider' he never had much to say. He would do a scene, just kind of nod, and then set it up to do it again. And you might do a scene 10 or 12 times or more, the same little 31-second bit. And you could tell he wasn't satisfied, but he wouldn't say much.
