It is through stage direction that many actors are truly taught how to act. They have had months of critiquing under a professional to ensure they execute their best performance possible. This is not the case in film. Film directors direct the scene, not the actors. In many cases, casting agents cast the actors and the director meets them at a table read or on set the day of the shoot. The directors trust that the actors are professional and do not need coaching. Film shoots are pressed for time. Time is money. A location is rented for a set amount of hours on a particular day and a director has to get as much filming done as possible within that set amount of time.
