The art of acting dates back thousands of years, so there’s a lot of different ideas and theories about it. However, you and/or your director will need to prep the actors for their roles, so you at least need to talk the talk. Don’t worry if you can’t tell the difference between the Stanislavski or Strasberg methods. Instead, concentrate on what you should be familiar with – the characters and their, well, characteristics. In fact, you can think of this as finding common ground with the actors. They should be just as interested as you are! And let them ask questions. If a character is supposed to be angry in a scene, be sure to explain why. “Because” works about as well as it did when your parents used it, except you have way less authority and control in this situation. Not to mention the fact that it makes you look like you don’t know, which will cause them to lose whatever respect they had for you on their way to leading the entire cast and crew in an on set mutiny. Of course, because you don’t want any of that stuff to happen, you’ll either admit you don’t know or discuss what’s driving that character’s anger while patiently suppressing any of your own.
Ok, if you must know Strasberg here’s an awesome video…
…and since you now know of Constantin Stanislavski and Lee Strasberg, you might as well learn about Michael Chekov.
