Directors this one is for you... Touch for an actor at the end.

As a director sometimes we want to be really detailed in our vision of the scene.  We already know where we want to shoot from, where we should light the actors, and what the physicality of the scene should already be.  Just like an actor we must not give ourself physical and emotional decisions and choices until we see what the scene's potential is.  If you have done a wonderful job in casting then give the actors a chance to create the real human behavior and movement of what that scene may be.  After you see what and where it could go then make your decisions, then see where you want to set up camera, you may see some wonderful and beautiful natural shots that you would not have seen if you would have projected your expectations of the scene on the actors.  Plus many times when a first time director gives directions they only give the physical direction which takes away from the natural human behavior of the actor.  It puts the actor in their heads about what they should physically be doing and they stop living.  I am not saying do not direct, but direct after you see what the natural blocking of the scene may become.  Film and television is not a stage play, it is human life and behavior that as a director it is our job to capture that reality on film.  Learn to direct an actor by choices, and objectives, keep them living, not roboticaly walking through the scene and spitting out lines that someone put on a page.

As for the actor, do not try to become the director.  Do not try to act the scene the way you see it in your head, if you do then you have now become a stage play.  You took any chance of that scene being real right out of the equation.   Live in the moment.  The blocking and the emotions must come from a natural state of being.  It must come from living in those circumstances.  "ACTING-creating real life in imaginary  circumstances."-A.S
