As we approach the release of Francis Ford Coppola's new film "Tetro," behind the scenes clips are constantly making their way to the web to track the progress of production.  This one is particularly entertaining because it provides a good look at how Hollywood operates.  Watch how uncomfortable the PA who delivers the chair appears to be... he gets no thank you or any hint of recognition from the director who carries on with his conversation like he didn't just demand that his rocking chair be brought over.  You can also tell that the PA feels out of place telling the actor he's got something on his arm.  It's proof that actors and directors are unapproachable, even for "below the line" crew who work directly with them day in and day out.  Talk about a thankless job...
